A dynamic eco-compensation standard for Hani Rice Terraces System in southwest China

Mastering the regional spatial differences of ecosystem service supply and ecosystem service demand is of great significance to scientifically planning the development and utilization of national land and maintaining healthy development of ecosystems. Based on the relationship analysis of ecosystem service supply and ecosystem service demand, this study explored the regional ecosystem service supply by ecosystem service value based on grid data and constructed an ecosystem service demand evaluation model that integrated the construction land ecosystem service demand equivalent for static aspects and the point of interest (POI) kernel density estimation for dynamic aspects on the basis of land use and POI data. In the end, it put forward a region division method for ecosystem service supply and ecosystem service demand and conducted an empirical analysis of Haidian District, Beijing. The following results were concluded: (1) the ecosystem service value of different grids in Haidian District was between RMB (Chinese monetary unit, Yuan) 0 and RMB 2.4787 million. In terms of spatial distribution, the ecosystem service supply took on an obvious trend of gradual decrease from the northwest to the southeast, with major ecosystem service supply coming from the northwest. (2) The construction land ecosystem service demand equivalent of Haidian District was characterized by a multicenter cluster: the high equivalent area was in the southeast, while the equivalent of the northwest was relatively low. POI kernel density estimation demonstrated cluster distribution, with a high kernel density estimation in the southeast, a lower kernel density estimation in the central part, and the lowest kernel density estimation in the northwest. The ecosystem service demand index also showed cluster distribution: high index in the southeast, low index in the northwest, and prominent sudden changes from the central part to the south. (3) The bivariate local spatial autocorrelation cluster diagram method was used to divide five types of ecosystem service supply and ecosystem service demand, namely non-significant correlation region, high ecosystem service supply and high ecosystem service demand region, high ecosystem service supply and low ecosystem service demand region, low ecosystem service supply and high ecosystem service demand region, low ecosystem service supply and low ecosystem service demand region. Grids with the highest ratio belonged to the non-significant correlation region; the distribution of low ecosystem service supply and high ecosystem service demand region had the greatest concentration, mainly in the southeast; the grids of high ecosystem service supply and low ecosystem service demand region were mainly present in the northwest and in a continuous way; the grids of low ecosystem service supply and low ecosystem service demand region, and high ecosystem service supply and high ecosystem service demand region were extremely few, with sporadic distribution in the central part. The research results could provide a basis for the adjustment and fine management of regional land use structure.

Discussing the spatial relationship between supply and demand of UGI ecosystem services is of great scientific significance for urban ecological construction and green space planning. Based on population, GDP, and land use data, this paper explored the spatial pattern between supply and demand of UGI ecosystem services in built-up area of Xi'an, and the spatial relationship between supply and demand of UGI ecosystem services in four urban functional areas were also analyzed. The results showed that the total UGI ecosystem service supply in Xi'an built-up area was 423 million yuan. The supply of ecosystem service gradually decreased from the edge of the study area to the central area, while the demand of ecosystem service showed the opposite change. The supply and demand of UGI ecosystem services in Xi'an had a significant negative spatial correlation, and there were significant differences among different functional areas of the city. The supply of UGI ecosystem services in built-up areas did not match the spatial distribution of urban demand of ecosystem services. It is urgent to coordinate the supply and demand of ecosystem services through rational UGI construction. 参考文献 相似文献 引证文献

Spatial patterns in ecosystem services supply and demand in the Jing-Jin-Ji region, China

Evaluating the ecological benefits of plantations in arid areas from the perspective of ecosystem service supply and demand-based on emergy analysis

Governments and non-governmental organizations have widely recognized tidal wetland restoration as a sustainable instrument to lessen the threat of climate change, which is reflected by the expansion of the spatial scale of coastal restoration projects. However, approaches to large-scale spatial planning of tidal wetland restoration remain sparse. Previous studies on site selection for restoration planning have focused on the potential supply of ecosystem services (ES) or restoration feasibility with less emphasis on the mitigation of the status of regional ES supply and demand mismatches. We developed a five-step workflow based on systematic conservation planning to identify priority areas for tidal wetland restoration and applied it to the coastal reclaimed areas of Shanghai, China. With this workflow, we analyzed the changes in spatial distribution and the potential ecosystem services supply and restoration costs of priority areas between the two different scenarios of ES demand ignored and ES demand considered. Results showed that the potential restorable areas only accounted for 31.4% (425.2 km²) of the original reclaimed area because of other land use demands (e.g., permanent basic farmland conservation). We extracted 50% of the potential restorable areas as priority areas based on Aichi Target 15. Compared with the ES demand-ignored scenario, the ES demand scenario resulted in a substantial increase in the priority areas of Baoshan District (~177%) and Pudong New Area (~15%) and a small decrease in Chongming District (~4%). No significant change in the potential ES supply for all priority areas was observed between the two scenarios. However, the total restoration cost of the ES demand scenario is 10% higher than that of the ES demand-ignored scenario. Our study highlights the importance of considering the status of regional ES supply and demand (mis)matches in large-scale spatial planning for tidal wetland restoration.

However, there are also numerous negative impacts of paddy production on the environment. Thus, to encourage farmers to engage in ecological or organic agriculture to provide more ecosystem services, it is necessary to pay farmers for their losses when they alter their cultivation practices. However, most current standards of ecological compensation for paddy cultivation are calculated by separate factors, such as the cost of ecosystem conservation, value of ecosystem services, or willingness to accept eco-compensation. As such, a standard is difficult to achieve for all the stakeholders and there is a lack of operability due to neglected factors. Thus, this study was conducted in the Hani Terrace, which was designated as a Globally Important Agricultural Heritage Systems (GIAHS) in 2010 and World Heritage in 2013, and we calculated the standard of paddy eco-compensation based on the subjective decision-making characteristics of individuals and paddy ecosystem characteristics. This study is based on the opportunity cost that ecosystem services supply with a goal of determining the supply curve for ecosystem services. First, through observation and sample testing, we compared the differences in the value of ecosystem services supplied by two production modes:conventional mono-cropping (use of chemical fertilizers and pesticides) and fish cultivation in rice fields (using half amount of fertilizers and no pesticides). Second, from the perspective of the microeconomic decision-making of individual farmers, we investigated the space distribution of opportunity costs for supplying paddy ecosystem services. Third, from the perspective of the macroeconomic behaviors of farmers, we investigated the relationship between the compensation standard and the eco-environment benefits willingly provided by the farmers. Finally, we combined famer willingness and the opportunity cost of ecosystem services, and the capacity of the majority to build an ecological-restoration oriented eco-compensation standard for the paddy system. The results indicated that the proportion of farmers converting their mode of production increased with the increase in the compensation payment. When the compensation payment amounted to 3000 yuan/hm2, the conversion ratio of cultivation practices reached 35.74%, the added value of ecosystem services was 80.77×104 yuan hm-2 a-1, and the required compensation funds was 91.04×104 yuan/a. When the compensation payment was as high as 9000 yuan/hm2, almost all farmers (97.12%) were willing to convert their mode of production; the added value of ecosystem services was 219.49×104 yuan hm-2 a-1 and the required compensation funds were 273.13×104 yuan/a. 参考文献 相似文献 引证文献

Ecosystems supply goods and services to humans and are the basis for sustainable development of human society. The study of the supply of ecosystem services and the demand and consumption of ecosystem services by human society, and the analysis of the supply and demand characteristics and flow relationships of ecosystem service flows are of great significance for the management of regional ecosystems and the development of ecological compensation. Taking the Yangtze River Economic Belt as an example, this paper calculates the supply and demand indices of ecosystem services in 2015 and 2020, and determines the ecosystem spatial flow paths and flow volumes from the ecosystem supply area to the demand area based on various methods and models such as the minimum cumulative resistance (MCR) model and distance decay model. The results indicate that 1). In 2015 and 2020, the supply and demand of ecosystem services in the Yangtze River Economic Zone show an increasing trend numerically, and there is spatial heterogeneity in the spatial distribution. In terms of ecosystem service supply per unit area, the midstream region is higher than the upstream and downstream regions. In terms of the demand for ecosystem services per unit area, the downstream is higher than the midstream and upstream. 2). From the supply-demand balance of ecosystem services in the Yangtze River Economic Zone, the midstream region is mainly the area of surplus supply of ecosystem services, and the downstream region is mainly the area of deficit supply. From 2015 to 2020, the number of areas with balanced supply and demand of ecosystem services in the Yangtze River Economic Belt decreases and the number of areas with unbalanced supply and demand increases, which is related to the changes in the level of economic development and land use patterns. 3). The flow of ecosystem services in the Yangtze River Economic Belt shows an increasing trend, from 726.59 billion yuan in 2015 to 1,450.54 billion yuan in 2020, with Jiangxi Province being the main ecosystem service supply area and Zhejiang Province being the main ecosystem service demand area in the Yangtze River Economic Belt.

Quantification and driving force analysis of ecosystem services supply, demand and balance in China

生态系统服务作为生态系统评估的核心领域,是生态学的研究热点。生态系统提供服务的形式与能力受人类活动强烈影响,反之,生态系统服务的变化又影响着人类相关决策的制定。不同生态系统服务之间很难甚至不可能同时达到利益最大化,即存在着不同程度此消彼长的竞争关系。此外,不同生态系统服务之间也可能形成相互促进或抑制的协同作用。探讨不同生态系统服务的相互关系(竞争与协同作用),有利于揭示不同尺度利益相关方与生态系统服务之间的作用与反馈机制,避免生态系统服务的重复估算;同时可为制定与实施生态补偿、提高人类福祉提供科学依据,优化生态系统服务管理。综合研究了近期国外生态系统服务竞争关系与协同作用的相关文献,在简述当前生态系统服务研究若干问题的基础上,以生态系统服务竞争与协同为视角,厘清了生态系统服务竞争与协同的基本内涵,总结了生态系统服务竞争与协同的主要类型,探讨了生态系统服务竞争与协同的空间与时间尺度效应;介绍并总结了生态系统服务竞争与协同两种主要研究方法(生态-经济综合模型方法、基于土地利用的情景分析法)的特点与适应范围。;Being the core of ecosystem assessment, studies on ecosystem services have been becoming a focus in the field of ecology. The formation and provisioning capacity of ecosystem services are tremendously affected by human activities. Conversely, the magnitudes of ecosystem service changes also influence the preferences of human being's daily decision-making. Investigation into the dynamics of the trade-offs and synergistic relationships of regional ecosystem services will shed light on interactions and feedbacks between ecosystem services and the stakeholders at different spatial and temporal scales, and avoid double-counting issue in ecosystem services assessment. In addition, information and progress on trade-offs and synergies in the delivery of ecosystem services will provide scientific basis for designing and implementing eco-compensation schemes and optimize the management behavior of ecosystem services, and finally improve human well-being associated with trade-offs and synergies among different ecosystem services.<br>It is revealed from this review that in the last decades, the valuation of ecosystem services has been received lots of attentions in the decision-making and scientific research communities. However, the double-counting issue during the valuation process usually leads to insufficient or biased guidance in the management of ecosystem services. Since ecosystem service is benefit that human receives from the natural ecosystems, the stakeholders' demand for ecosystem services from different spatial and temporal scales often causes competitions and conflicts among ecosystem's various goods and services. The interactions between human being and ecosystem services often give rise to trade-offs and synergies which in turn directly affect human welfare.<br>With regard to the terminologies, trade-offs between ecosystem services refers to the enhancement of one ecosystem service locally in a short term is at the cost of other ecosystem services locally or at a large spatial scale (e.g., globally) in the future. It can be simplified as the win-lose mode. The term synergies means the synchronous changes between two or among many different ecosystem services, including the win-win mode and the lose-lose mode. The trade-offs and synergistic relationships exist not only within different categories of provisioning services, but also among different ecosystem services and like provision services, regulation services, cultural services, and supporting services. Findings from about 12 literatures has shown specific examples of such kind of trade-offs and synergistic relations, for instance, among provisioning services, between regulating services and cultural services, between provisioning services and supporting services, among regulating services, and between provisioning services and regulating services. The spatial scale of trade-offs and synergies contain various scales, for instance, from ecological scale to institutional scale. The temporal scale could be short-term to long-term based.<br>This paper indicates that so far, trade-offs and synergies analysis of ecosystem services is still at its early stage. However, we identified and summarized two research approaches which have already been commonly used for the analysis of ecosystem services' trade-offs: (1) the Integrated Ecological-Economic Model: it is a traditional approach which is often used to quantify trade-offs. The Model consists of several ecological and economic models. The ecological models are mostly used to analyze the magnitudes of the changes of ecosystem services, while the economic models to evaluate the impacts of the change on human welfare. Since land use and land cover change serves as a direct driving factor of the ecosystem services' trade-offs and synergies, it will become even more extensive due to intensification of interactions between the two in the future. (2) Scenarios Analysis based on Landuse is attracting more and more attention in scientific literature. Remote sensing data and management policies of ecosystem services provide strong data basis for the scenarios formulation and analysis. It could provide more objective and spatially-explicit information on the trade-offs and synergies for optimizing ecosystem services management.

With the acceleration of urbanization, the ecological environment has gradually deteriorated, the supply and demand relationship of ecosystem services has gradually become unbalanced, and human well-being has been seriously threatened. In particular, coal-using cities are facing the dual pressure of the ecological environment and resource depletion due to the concentration of population and resources, and environmental contradictions. Thus, exploring the relationship between the supply and demand of ecosystem services and their evolution help promote scientific ecological management. By using multi-source data from Huainan City in 2010 and 2020 and the ecosystem service supply and demand matrix and ArcGIS quantitative measurement of the supply, the demand and supply of ecosystem services in Huainan City were investigated. The result implies the following. (1) During 2010‒2020, the supply of ecosystem services in Huainan has decreased year by year. In terms of spatial distribution, the ecosystem service supply in Huainan City was high in the south and low in the north, and there is a significant regional differentiation, (2) Between 2010 and 2020, the demand for ecosystem services in Huainan City increased year by year, and its spatial distribution was similar to the distribution of ecosystem service supply. (3) Due to the decline in the supply of ecosystem services between 2010 and 2020, the demand for ecosystem services has increased, which leads to changes in the matching degree of supply and demand of ecosystem services in Huainan City.

Evolution and coupled matching of ecosystem service supply and demand at different spatial scales in the Shandong Peninsula urban agglomeration, China

Most finance to halt desertification also benefits multiple ecosystem services: A key to unlock investments in Land Degradation Neutrality?

Ecosystem services (ES) mapping is attracting growing interest from landscape and urban planning, but its operationalization in actual decision-making is still limited. A clear distinction between ES capacity, flow and demand can improve the usefulness of ES mapping as a decision-support tool by informing planners and policy-makers where ES are used unsustainably and where ES flow is failing to meet societal demand. This paper advances a framework for mapping and assessing the relationships between ES capacity, flow and demand with a focus on the identification of unsatisfied demand. The framework was tested in the Barcelona metropolitan region, Spain, considering two ES of critical relevance for the urban population: air purification and outdoor recreation. For both ES, spatial indicators of capacity, flow, demand and unsatisfied demand were developed using proxy- and process-based models. The results show a consistent spatial pattern of all these components along the urban-rural gradient for the two ES assessed. The flow of both ES mainly takes place in the periurban green areas whereas the highest capacity values are mostly found in the protected areas located on the outskirts of the metropolitan region. As expected, ES demand and particularly unsatisfied demand are mostly situated in the main urban core (i.e., Barcelona and adjacent cities). Our assessment also reveals that the current landscape planning instrument for the metropolitan region mostly protects areas with high capacity to provide ES, but might lead to declining ES flows in periurban areas due to future urban developments. We contend that the mapping of ES capacity, flow and demand can contribute to the successful integration of the ES approach in landscape and urban planning because it provides a comprehensive picture of the ES delivery process, considering both ecological and social underlying factors. However, we identify three main issues that should be better addressed in future research: (1) improvement of ES demand indicators using participatory methods; (2) integration of ecological thresholds into the analysis; and (3) use of a multi-scale approach that covers both the local and regional planning levels and cross-scale interactions between them.

People require multiple ecosystem services (ES) to meet their basic needs and improve or maintain their quality of life. In order to meet these needs, natural resources are exploited, threatening biodiversity and increasing the pressure on the Earth's ecosystems. Spatial-structural approaches are used to explain and visualise the spatial relationships and connections between areas that provide and benefit from ES. However, areas where the demand for these ES occurs are rarely considered in existing spatial approaches or equated with areas where people can use the benefits. In order to highlight the differences between these two areas, we would like to introduce the 'Service Demanding Area' (SDA) in an adapted spatial-structural approach. This approach relates SDA to already familiar ES provision and use units, namely Service Providing Areas (SPA), Service Connecting Areas (SCA) and Service Benefitting Areas (SBA) and can be used to schematically illustrate, understand and analyse the different forms of demand that can emerge. A literature review was conducted to provide an overview of the spatial mapping of ES demand. Three issues arose that should be addressed to improve the assessment of ES demand: 1) The term ES demand is not used consistently. To avoid confusion, it is important to clarify how ES demand is understood and how it differs from the other components of the ES concept (e.g. ES supply, ES potential, ES flow); 2) It is important to consider that ES demand is multi-faceted and is generated on different geographical scales, including the full range of stakeholders' perceptions, needs and desires which broadens the picture of societal demand for ES; 3) Meaningful interpretations between ES supply and demand need to be available to inform decision-makers about interventions for reducing ES trade-offs and mismatches.
