Temporal-spatial evolution of the integrated landscape patterns in the Zhengzhou Metropolitan Area based on nighttime light data

Metropolitan integration development refers to the interconnection between cities and the coordinated development of various aspects such as economy, society, culture, and nature, which is the goal of metropolitan area development. With the Zhengzhou metropolitan area as the research area and based on nighttime light data from 2012 to 2021, we comprehensively used landscape index and landscape morphology spatial pattern analysis methods, systematically evaluated the integration process of the metropolitan area from the perspective of spatial expansion and spatial connection, analyzed the spatiotemporal variations of the landscape pattern of the metropolitan area, and revealed the spatiotemporal expansion and connection patterns of the metropolitan area. The results showed that the area of the Zhengzhou metropolitan area expanded year by year from 2012 to 2021, with the number of landscape patches continuously increasing, showing an agglomeration phenomenon. In the metropolitan area, there was a trend towards stability and multi-directional coordinated growth. The contribution of non-central cities to expansion increased annually, while the expansion patterns of various constituent cities gradually shifted from internal filling to external expansion. The connection scale within the metropolitan area had been expanding annually, with enhanced intercity connections. Intercity connection belts and channels for material and information exchange were emerging, and the integrated network of urban agglomeration connections was gradually forming. Metropolitan integration planning provided positive guidance for the development of metropolitan areas. We should fully leverage the driving effects of metropolitan areas, pay attention to the integration of Zhengzhou-Kaifeng and Zhengzhou-Xuchang, promote the formation of emerging growth poles in Xinxiang and Jiaozuo, as well as regional coordinated development, strengthen the network of policies, economy, transportation, information, etc., and form a diversified and integrated development situation.

Assessing the Feasibility of Establishing special Economic Zones: Geo-economic Mapping Method

The purpose of the study is to systematize factors of successful and sustainable functioning of special economic zones, as well as to develop tools to map of zones on a map of a country with the competitive advantages of individual territories identified therein in order to make recommendations for improving the zonal policy. The relevance of the study is due to the fact that in the context of global shocks, a special preferential regime, flexible governance models of special economic zones are not determinants of their successful application in order to promote national investment strategies. The geo-economic advantages of the territories within which the special economic zones operate come to the fore. Such advantages are the basis for the formation of poles of economic, commercial, industrial and innovative growth. The use of methods of theoretical (analysis, synthesis, generalization) and empirical (comparison, measurement) research allowed the authors to reveal the content of effects associated with the functioning of special zones, to highlight the problems of their measurement; to generalize the features of preferential regimes of Russia; to systematize the geo-economic factors of successful and sustainable operation of special zones. The method of geo-economic mapping was used to identify the correspondence between the competitive advantages of territories and special zones created within their borders. As a result, it is proposed to classify key geo-economic factors that determine the potential successful functioning of special zones into three groups: spatial, economic and organizational. These groups of factors, according to the authors, should be considered in terms of formation and retention of geo-economic advantages: general, caused by public management and specialized. The method of geo-economic mapping identifies regions whose special zones correspond to the level of development of the identified geo-economic advantages, as well as those whose conditions are most likely not to maximize the effect of the special zones localized in their territory. It is recommended to establish a system for monitoring the conformity of specialization of regions with the profile of special economic zones established within their borders.

Study of Urban Growth Center Development Factors and Simulation The Mamminasata Urban Area

Urban growth starts from a center and affects the surrounding areas, this is due to the emergence of additional centers that will each function as growth poles, to study the dynamics related to urban growth center information, several data and extraction and analysis methods are needed. This study examines several methods of extracting information on urban growth centers from Landsat 8 OLI/TIRS in 2013 and 2023 by utilizing the spectral resolution of Landsat imagery in the Mamminasata area, and integrating spatial modeling to simulate the growth centers of the Mamminasata area in the next 10 years (2043). The results of this research classification method show an accuracy rate of 71.48%. The results of the determinant factor test show that the most influential factors are the distance from the center of shops, slope, then the distance from the university, and the distance from the main road in 2013-2023 Mamminasata Urban Area. The results of this variable drive test are then used in spatial simulations using the markov chain simulation method in the LCM module and show an increase in the area of the growth center in the Mamminasata region, for the entire scope of the Mamminasata region, the Makassar City area shows the highest intensity of regional growth centers and becomes the center of growth in the Mamminasata urban area. The planning concept applied to the results of this study is based on resources, geographic location, and factors affecting the growth center.

Reform of Decentralization of Power in Ukraine under Conditions of War: Legal Regulation, Management Features and Directions for Improvement

The purpose of the article is to reveal the reform of the decentralization of power in Ukraine under conditions of war. In the concept of the territorial community of Ukraine, ancient European traditions of Ukrainian local self-government and modern standards of the European Union have been successfully embodied. The productive interaction of citizens, the state, and international organizations contributed to formation of Ukrainian territorial communities. It has been proven that the personal income tax is one of the main sources of filling community budgets. For 9 months of 2022 local budgets of the Dnipropetrovsk region of Ukraine received 16,364,124 Ukrainian hryvnias (UAH) as personal income tax, which is 34% more than for the same period in 2021. Methodology: The specifics of the research subject, as well as its purpose and tasks determined the use of general scientific and special methods of scientific cognition. Stabilization and restoration of territorial communities in Ukraine require the introduction of a new three-level effective and transparent system of strategic planning: state strategy — regional strategies — community strategies. For restoration and stimulation of regional development strategizing should contain definition of the following four functional types of territories: territories of recovery, poles of economic growth, territories with special conditions for development, territories of sustainable development.

Development, Informal Sector and Policy Making: An Assessment of the Role of Policy Formulation in the Operationalization of Informal Groups in Harare Urban

The major thrust of this paper is to understand an interaction between development and its major irreducible determinants; that is public participation and policy formulation. Development is a term that has a multifaceted forms and definitions (Rodney 1982; Saul 2006). It is a process of bringing about desirable change and citizenry participation is critical in such processes that bring positive changes in the socio-economic lives. From an Interactionist perspective, it can be argued that, human relations from a micro-view point are characterized by multidimensional interactions imbedded in various symbiosis. Such explains the interaction between citizens and institutions of power and ideology. Conventionally, disparities in terms of development are due to natural distribution of resources (Weiss 2007; Okupu et al 2018), but this paper conceptualizes it largely as a neglection on the part of institutions, dearth of unity among the citizens and also limited interaction between the development agencies and the people. Development remains a peculiarity within boundaries of the propulsive growth poles while some parts are lagging behind due to lack of positive symbiosis between citizens and institutions. Contemporary researches demonstrate largely that policy formulation and implementation lack correlation and the intended development is jeopardized to the detriment of the welfare of the people. Saliently, there is need for the prioritization of the citizen participation in policy making so that implementation would be feasible and easier. The reciprocity between the infrastructure, (physical enablers and population) and the superstructure (decision makers, intellectuals and researches) must be explored with much consistence and coordination. In Zimbabwe, particularly in the Harare’s informal sector and in deed in many African countries such is missing, thus, making poverty levels cyclical, structural and endemic.

Study of The Impact of The Establishment of A National-level Airside Economic Zone on The Regional Economy

In recent years, many governments have cultivated the airside economy as a new growth pole in their regions, and the construction of national airside economic zones has played an essential role in promoting economic development, enhancing international competitiveness, and facilitating industrial transformation and upgrading. The development is still in the primary stage, and there are some problems, such as uneconomical scale and the gradual weakness of driving regional economic growth. This paper analyzes the policy effects and transmission mechanism of national-level airside economic zones and regional economic development based on the panel data of national-level airside economic demonstration zones from 2012 to 2022, using the propensity score matching-multiple-period double-difference method. The study shows that establishing national-level airside economic zones significantly improves regional economic development. However, there are problems such as irrational industrial structure, and local governments and airport authorities should plan the construction of airside economic zones in a coordinated manner and accelerate the construction of industrial clusters.

Evaluating future flood risk mitigation capacities in major cities across China

Rapid urbanization and climate change have significantly altered urban hydrological processes. Previous research has highlighted their adverse effects on escalating risk of urban flood. Nevertheless, few assessments have quantified how future urban flood risk mitigation capacities evolve under various urban expansion and climate change scenarios. This study simulates urban expansion of major cities across China using future urban-regional environment simulation model at 30-m resolution under shared socioeconomic pathways scenarios (SSP). Concurrently, future precipitation intensity changes are assessed based on climate projection data. Finally, the urban flood risk mitigation capacity impacted by urban expansion and climate change is evaluated using the soil conservation service model. The results reveal: (1) The sizes of major cities are projected to expand 30% by 2050, and the north and east China are primary urban growth poles. (2) Major cities' precipitation intensity increase 0.4% in SSP126, but decline 5.4% and 2.3% in SSP245 and SSP585. (3) The flood risk mitigation capacities of major cities decrease 2.7% in SSP126 and 2.1% in SSP585, but increase 0.2% in SSP245. Most cities experiencing capacity decrease are located in the north and east China. These results provide valuable insights for the formulation of future urban flood adaptation and mitigation strategies.

Exploring the influence of natural and cultural environments on tourism demand: a spatial analysis

ABSTRACT This study integrates natural and cultural environmental factors within a unified framework, exploring their specific effects on tourism demand in China. To more effectively account for spatial dependence and variable heterogeneity in tourism demand, we utilize the spatial Durbin model in analyzing provincial-level data spanning from 2007 to 2019. Research findings reveal: (1) Both domestic and inbound tourism display significant spatial association. (2) Natural and cultural factors exhibit spatial spillover effects on domestic tourism demand, exemplified by sulfur dioxide generation and intangible cultural heritage quantity. (3) The impact factors or mechanisms of natural and cultural environment on domestic and inbound tourism share some similarities, but differences still exist. For instance, intangible cultural heritage prosperity stimulates regional domestic tourism but only affects local inbound tourism. This study, using China as a case, offers a practical approach and theoretical perspective for probing into the emergent growth poles in tourism demand.

Mapping material stocks in buildings and infrastructures across the Beijing–Tianjin–Hebei urban agglomeration at high-resolution using multi-source geographical data

Spatial patterns of material stocks in buildings and infrastructures are crucial for understanding resource use, spatial planning and environmental management. So far, spatially explicit stock-driven approaches face substantial data limitations, requiring costly and time-intensive efforts to map stocks at urban micro-scales. Herein, we developed a volume-based framework for material stocks mapping in buildings and infrastructures at a 10 m resolution, applied across the entire Beijing–Tianjin–Hebei urban agglomeration (BTH-UA) in China, a key growth pole for regional economic development. We integrated multi-source remote sensing data, GIS products, crowdsourced data, and material intensity databases, covering ten bulk materials. The findings reveal that the total mass of buildings and infrastructures in BTH-UA amounts to 195,000 Mt, equivalent to 182 t/cap, 2.43 Mt/km2. Material stocks are spatially clustered and correlate with the population size and economic activity of the secondary industry. This research contributes to the quantitative description and detailed mapping of material stocks in built environment.

The dominant three-element model of oil and gas accumulation in basement buried hills: A discussion on new exploration frontiers in the deepwater area of the northern South China Sea

Basement buried hill reservoirs represent significant emerging prospects among the newly discovered growth poles in the deepwater areas of the northern South China Sea. Addressing the unclear key factors contributing to their formation, this study dissects successful global exploration cases of basement buried hill reservoirs and analyzes the common characteristics of basement reservoir accumulation under different basin types, structural backgrounds, basement lithologies, and oil and gas geological conditions. A three-element coupling relationship, termed “source-reservoir-cap”, is proposed as the dominant mechanism controlling basement buried hill reservoir formation. The genesis of these reservoirs requires adequate oil and gas supply, appropriately sized accumulation bodies, and effective sealing layers. The optimal configuration of the “source-reservoir-cap” relationship directly influences the efficient charging and preservation of oil and gas within basement buried hill reservoirs. Four configurations are identified, including circumstances such as the source-underlying low-positioned basement buried hill with a “source-reservoir cover docking migration type”, the source-border middle-positioned basement buried hill with a “source-reservoir lateral window docking migration type”, and the source-outside high-positioned basement buried hill with both “source-reservoir short-distance transport and migration type” and “source-reservoir long-distance transport and migration type”. The first to three models present favorable accumulation conditions. Based on the “source-reservoir-cap” three-element coupled model, this study identifies the Yunkai basement buried hill in the Pearl River Mouth Basin, the central depression in the Qiongdongnan Basin, and the northern and southern basement buried hills belts as crucial exploration targets in the deepwater areas of the northern South China Sea.

Internal Causes, Challenges and Realization Paths of Regional Coordinated Development to Promote Common Prosperity

Realizing regional coordinated development is not only conducive to implementing the new development concept, but also conducive to building a new development pattern and realizing the goal of common prosperity. However, at present, there are some problems, such as the gap between the northeast and the east, middle and west, the gap between the north and the south and the internal gap of the "the belt and road initiative", the spatial layout of metropolitan areas and urban agglomerations is dense in the east and sparse in the west, and the cooperation process between regions is slow. During the "Tenth Five-Year Plan" period and in the future, we should focus on cultivating economic growth points, taking county towns and central villages (towns) as important nodes of urban-rural integration and development, and metropolitan areas and urban agglomerations as growth poles to promote the construction of cross-regional economic belts; Focus on the construction of major economic belts and build a criss-crossing regional coordinated development network; Take "the belt and road initiative" as the guide and accelerate the construction of a new development pattern.

Rethinking Afriruralization for fiscal policy of economic sustainability of Nigeria: Interrogating François Perroux’s growth poles theory.

Migration today occurs because of urbanisation and industrialization at varied degrees in every country for a better life. This paper thus focuses on the process of implementing fiscal policy of economic ruralisation development through the pragmatism of glocal contents for an economic sustainability. Thus, using the concept of Glocalization or Glocalization (a portmanteau of globalization and localism) in the simultaneous universalizing and particularizing Afriruralization tendencies in contemporary social, political, and economic systems. The question how Afriruralization can influence its realisation in countries like Nigeria require urgent interrogation. In interrogating François Perroux’s growth poles theory, this work presents arguments in support of the proposition that Afriruralization is an inevitable component of the development process, through diversification which necessarily could result in propitious stimulus. This wave of analysis could bring about what we termed glocal afriruralization theory. With value-laden policies, this process can occur at a socially acceptable level. However, given the distortion of opportunities in favour of cities in most developing countries, Nigeria not excluded, the costs of livelihood associated with urbanisation often offset the benefits, leading to disproportionate ruralisation. To this end, glocal Afriruralization theory which is back to baseruralisation is the option for reinventive, creative and resourceful diversification development culture needed for growth.

Spatial-temporal characteristics and influencing factors of carbon emission in Chengdu-Chongqing area: an urban transportation perspective.

The Chengdu-Chongqing twin-city economic circle is a vital growth pole and a new power source for Chinese high-quality development. Studying the spatial-temporal characteristics of carbon emissions and the role of factors affecting them under the transportation perspective is of great significance for this region to realize the carbon peak and carbon neutrality and to formulate carbon emission reduction policies. We use the exploring spatial data analysis (ESDA) and spatial regression model combined with the STIRPAT model, and research finding: (1) The total carbon emissions in the research area gradually increased from 2014 to 2020, but the growth rate showed a significant decline in 2019. (2) There is significant spatial heterogeneity of carbon emissions in the study area; the hotspot areas of total carbon emissions are in Chongqing and Chengdu, forming a high-low aggregation of carbon emissions. Per capita carbon emissions show a high trend in the southwest and a low in the northeast. (3) From the factors of transportation perspective, highway density and private vehicles have a positive impact on carbon emissions, and urban road areas and public transportation have a very significant inhibition of carbon emissions and a spatial spillover effect. (4) Other factors, such as population size, national economic development, urbanization level, and industrial structure, all have a positive effect on carbon emissions, and disposable income has a negative effect on carbon emissions.

Study on multi-scenarios regulating strategy of land use conflict in urban agglomerations under the perspective of “three-zone space”: a case study of Harbin-Changchun urban agglomerations, China

Introduction: Against the background of rapid global urbanization, the urban space expansion has led to increasingly acute land-use conflicts. Accurately understanding the spatial and temporal evolution characteristics of land-use conflict patterns and measuring the level of spatial conflicts are crucial for intensifying sustainable use and management of land resources. Existing research focuses on analyzing the current status of land-use conflicts, while there is limited discussion on tracking spatial-temporal dynamic patterns and simulating future conflict trends.Method: In this paper, the level of spatial conflict was measured by constructing a spatial comprehensive conflict index (SCCI) model, and the spatio-temporal evolution characteristics of land use conflict in Harbin-Changchun urban agglomeration from 2000 to 2020 are discussed. In addition, the PLUS model is used to simulate and predict the pattern of land use conflict in 2030, finally put forward the control strategy.Results: Result shows that: (1) Over the past 20 years, urban space has expanded rapidly with two provincial capitals as growth poles. Land-use conflicts generally exhibit a distribution pattern of “high in the west and low in the east, high in the core and low in the periphery.” (2) During the past 20 years, conflicts have intensified initially and then eased. Severe uncontrolled conflicts are concentrated in the transition zone between urban and rural areas of urban agglomerations. (3) Agricultural space is the core resource and key area contested by different interest subjects in the process of land development and utilization.Discussion: The agricultural space priority scenario proves to be the most effective in controlling spatial conflicts. However, a single space priority scenario cannot adequately address multiple spatial rights and interests. Therefore, different spatial management modes should be implemented in different areas. The purpose of this paper is to provide scientific strategies and suggestions for controlling land-use conflicts in urban agglomerations and achieving sustainable development of regional land use.

Research on the Innovation Strategy of Regional Logistics Supply Chain System Under the Background of Digital Economy

Based on the continuous application and development of digital information technology, the digital economy has gradually become an important growth pole of China's economic development. Digital development has also provided new opportunities for the transformation and upgrading of logistics and supply chains, and the coordinated development of the digital economy and regional logistics supply chains has achieved remarkable results. However, in the process of promoting the development of the logistics supply chain, the digital economy has problems such as the imbalance in the digitization of the logistics supply chain system, the lag in the global response speed, and the lack of trust mechanism, so it is necessary to optimize the logistics supply chain management process, strengthen the information interaction and integration between the upstream and downstream node enterprises of the logistics supply chain, and connect up and down, strengthen the elasticity and resilience of the logistics supply chain, and establish and improve the trust mechanism of the logistics supply chain system, so as to accelerate the development of the digital economy and the logistics supply chain.

Multi-decadal coastal change detection using remote sensing: the Mediterranean coast of Egypt between El-Dabaa and Ras El-Hekma

A key source of information for many decision support systems is identifying land use and land cover (LULC) based on remote sensing data. Land conservation, sustainable development, and water resource management all benefit from the knowledge obtained from detecting changes in land use and land cover. The present study aims to investigate the multi-decadal coastal change detection for Ras El-Hekma and El-Dabaa area along the Mediterranean coast of Egypt, a multi-sectoral development area. Besides, the superiority of the area is highly dependent on its proximity to three development projects: the tourism and urban growth pole at Ras El-Hekma, the beachfront Alamain New Mega City, and the Nuclear Power Plant at El Dabaa. This study utilized multi-spectral Landsat satellite images covering 1990, 2010, and 2020 to perceive the post-classification change detection analysis of the land use and land cover changes (LULCC) over 30 years. The results of the supervised classification from 1990 to 2020 showed a 47.33 km2 (4.13%) expansion of the agricultural land area, whereas the bare soil land area shrunk to 73.13 km2 (6.24%). On the other hand, the built-up activities in the area launched in 2010 and escalated to 20.51 km2(1.77%) in 2020. The change in land use reveals the shift in the economic growth pattern in the last decade toward tourism and urban development. Meanwhile, it indicates that no conflict has yet arisen regarding the land use between the expanded socioeconomic main sectors (i.e., agriculture, and tourism). Therefore, the best practices of land use management and active participation of the stakeholders and the local community should be enhanced to achieve sustainability and avoid future conflicts. An area-specific plan including resource conservation measures and the provision of livelihood alternatives should be formulated within the National Integrated Coastal Zone Management (ICZM) plan with the participation of the main stakeholders and beneficiaries. The findings of the present work may be considered useful for sustainable management and supportive to the decision-making process for the sustainable development of this area.

How changes in landscape patterns affect the carbon emission: a case study in the Chengdu-Chongqing Economic Circle, China.

The construction of low-carbon cities is an optimal means to balance the competing interests of economic growth and carbon emission reduction. This study focuses on the optimization of land use patterns with a low carbon orientation, taking the Chengdu-Chongqing Economic Circle (CCEC), the fourth-largest economic growth pole in China, as an example. The panel data regression analysis is carried out to identify the dynamic correlations between the landscape changes and the carbon emission induced by land use and land cover change (LICE) of each city, each year, for the last 20 years. The results show that the CCEC has witnessed a 142.85% increase in carbon emissions during the period studied, with the growth of built-up land contributing 94% of total carbon emissions from 2000 to 2020. By constructing the panel regression model, this study finds that the intensity of carbon emissions increases significantly as the urban built-up land area and the agglomeration of artificial structures increase. The conversion of cropland, which dominates the landscape pattern, to built-up land has led to further fragmentation of the landscape pattern and a reduction in LPI, thus increasing carbon emissions. And a more complex regional landscape pattern will have a positive impact on carbon emission reduction. Based on the above findings, suggestions are articulated for carbon emission reduction.

Analysis of the Competitiveness of Coastal Space Using Taxonomic Methods

Valorization of space in the investment aspect is the main direction of verification of areas that can be differentiated or show emerging poles of economic growth in the local, regional context, and even with an impact on the functioning of the country’s economy. For this purpose, this study attempts to show the competitiveness of the seaside space and the impact of port functions on all changes in the environment, showing the determinants that differentiate municipal areas.
