Optimization Strategy of Landscape Ecological Planning in Urban Green Space System

In recent years, China’s urbanization process has increased year by year, and the environmental problems brought by it have become increasingly prominent. The urban ecological environment and urban green space are closely connected. The improvement and reconstruction of the ecological environment need to be realized through the urban green space system planning. Therefore, it is imperative to apply landscape ecology in the urban green space system planning. This paper first outlines the important role of urban green space systems in restoring ecological and environmental problems. Second, based on the research on the landscape ecological progress of urban green space systems at home and abroad, through in-depth investigation of some representative urban green space systems in China, the current domestic Problems existing in urban green space system planning. Finally, based on the principles of landscape ecology, an optimization strategy for landscape ecological planning in urban green space systems was proposed. The results show that the use of landscape ecology can rationally plan the landscape space, green space corridors, green space patches and other factors in the green space system, thereby achieving the purpose of improving the urban environment and promoting ecological balance.

Research on Urban Green Space System Evaluation Index System

“Green space” is the lung of the city. The rational planning and protection of green space is crucial to the construction and development of the city. This paper mainly analyzes the problems existing in China’s current urban green space system planning indicators, discusses the principles and index system for establishing the urban green space system index system, and proposes a new concept of ecological and three-dimensional greening represented by the green quantity rate. It analyzes the relationship between urban green space system and urban planning, the impact factors of resource reserve and environmental pressure in green space system planning and their effects, and controls and localizes from urban spatial structure, shape, urban land use, environmental quality and population size demand. From the perspective of detailed control, a resource-saving and environment-friendly urban green space system planning evaluation index system is constructed to provide operational decision guidance for urban planning.

Spatial Equity Measure on Urban Ecological Space Layout Based on Accessibility of Socially Vulnerable Groups—A Case Study of Changting, China

The improper layout of urban public parks leads to the difference between citizens sharing or not sharing this kind of public resource, particularly in the historical districts of mountainous cities in China. The purpose of this study is to explore the spatial equity and quantitative measures of urban public parks’ layouts by building a demand index of socially vulnerable groups sharing public parks based on the accessibility evaluation model. In this paper, Changting—a famous national historical and cultural city—is taken as the empirical object, then the accessibility and social equity of public parks is quantitatively measured with the aid of the field investigation method, the spatial analysis model of geographic information system (GIS) and the SPSS statistical analysis method. The results indicate that it is feasible to measure the spatial equity of urban public parks with the accessibility and demand index of socially vulnerable groups, and it can effectively characterize the rationality and social equity of urban ecological space. It shows that a degree of spatial mismatch exists between the distribution of urban public parks and that of residents, that is to say the spatial distribution of public parks is not equitable in terms of accessibility or residents’ demands. Therefore, the data suggest that the spatial patterns and accessibility levels of parks in Changting County—especially the historical districts—should be further improved and perfected to achieve high levels of accessibility and equity through urban green space system planning. The paper may be used as a scientific reference for the planning and construction of ecological urban spaces. It can also provide useful decision-making guidance for urban planners in investigating, analyzing, and adjusting the distribution of public service facilities to achieve equitable outcomes, while promoting the harmonious and sustainable development of mountainous cities.

An Evaluation on Urban Green Space System Planning Based on Thermal Environmental Impact

From the ecological effect of urban green space system, this paper illustrates the necessity and importance of inter-disciplinary evaluation of the urban green space system from the ecological perspective and analyzes the mechanism of action of urban green space in relieving the heat island effect. The quantitative evaluation approach for the thermal environmental impact of urban green space system is proposed utilizing GIS technology. Zhuzhou is taken as an example for practical application of the approach. Lastly, priority issues in relation to urban green space system planning and quantitative evaluation are discussed.

A MSPA-Based Approach of Urban Green Space System Planning

Urban green spaces are considered as the life support system in a city, if systematically planned, developed, and maintained, they may provide various ecosystem services in a sustainable way. By integrating the morphological spatial pattern analysis (MSPA) and the green infrastructure (GI) network based on GIS, this study provided an urban green space planning method to guide urban sustainable spatial development and land use decisions in the Longgang District of Shenzhen in China. The approach has a robust performance in identifying the vital hubs and linkages in the urban green space system. It is hoped that this plan model based on MSPA, the function connectivity of urban green spaces could be farther strengthened so that some key zones in landscape pattern could be protected in the future development.

Study on Urban Green Space System Planning Based on Ecological Suitability Evaluation: A Case of Luancheng City in China

For a long time, planners get used to apply qualitative analysis and subjective knowledge to define urban green space system. Lacking support of quantitative analysis, the incomplete inventory will result in subjective evaluation, low pertinence. And the required depth and level for planning will not be strong enough. This study strives for introduce ecological suitability evaluation to urban green space system, derives the supporting theory, framework, and evaluation model. By using GIS, Luancheng green space system is generated based on the ecological suitability analysis. Also, this study shows that green space system planning is more operational and reliable based on ecological suitability evaluation.

Analysis of problems in urban green space system planning in China

This paper discusses the major problems in urban green space system (UGSS) planning at both general and special planning levels in China. At general planning level, the problems of the UGSS are mainly from the ignorance in the characteristics of urban nature spaces and the limitation factors of the urban planning system. Great importance is attached to the green spaces in the built area of city, but the green spaces in surrounding areas of the city is unnoticed. Furthermore, because the area of UGSS planning is strictly limited by the administrative zoning, the green space system loses its integrity and rationality in spatial patterns. The schedules of urban development planning mismatched the paces and progresses of the ecological restoration cycles. At special plan level, the problem of the UGSS in China is that the green spaces quantity was over emphasized but the rationality of their layouts is neglected.. Meanwhile, the requirement of the spatial structures and the green spaces layouts to balance between the urban development and the natural ecological environments is often ignored. With regard to the layouts in the UGSS planning practices, the existing problems are the compromising to the existing land-uses, the ‘filling in’ approach to plan green spaces and an over-emphasis on the layout patterns.
