Abstract
AbstractWith the acceleration of urbanization, the increase of urban population has led to earth-shaking changes in urban structure. The structure and function of urban ecosystem have changed, which has affected the service function of urban ecosystem. Urban ecosystem services are closely related to human well-being. Therefore, quantifying urban ecosystem services can better guide urban planning and optimize urban structure. In this chapter, we take China as case study to assess the urban ecosystem services from multiple scales, take Chongqing of China as case study to assess ecosystem service flow, and analyze the entropy value and entropy flow of ecosystem. Firstly, the ecosystem service cluster model was constructed to analyze the changes of ecosystem services in different provinces of China. Secondly, a cluster analysis model was established to group different provinces based on the national scale. Finally, an integrated analysis with the assessment matrix and entropy flow method was used to spatially identify and effectively quantify the ecosystem services flow of Chongqing, China. Our methods and findings can provide theoretical guidance for urban landscape planning, management, and policymaking by considering the ecosystem services and ecosystem health of urban scale.KeywordsUrban ecosystem servicesEcosystem service flowAssessment matrixEntropy flow
