Strategies of Critical Areas of Ecological Space in High-density Urban Areas from the Perspective of Ecosystem Supply and Demand-A Case Study of Guilin
Integrated management of ecosystem services is an important way to ensure urban ecological security and optimize the spatial pattern of national territory.With scarce ecological space,high pressure on ecological environment,and diverse needs of residents,the central urban area was confronted with a strong spatial differentiation between the supply and demand of ecosystem services and complicated ecological management.Therefore,the quantification of urban ecosystem service supply and demand,and identification of spatial distribution differences between ecological supply and residents'demand,is an important way to enhance the efficiency of ecosystem service supply,and also a key to supporting scientific planning and management of urban land use.In this study,based on ecosystem services supply-demand ratio,the supply and demand of seven ecosystem services,namely water conservation,cooling effect,rainfall regulation,carbon sequestration,soil conservation,biodiversity protection,and recreation,in the central urban area of Guilin were measured as an example.The supply-demand bundles of ecosystem services were identified by cluster analysis.Coupling supply-demand matching and imbalance zones and ecological protection zones,and three levels of ecological conservation zones and two types of restoration zones are delineated.Based on the zones of ecological characteristics and the supply-demand of ecosystem services,the grading and classification management and control guidelines were proposed This study can provide a reference for urban planning and management of ecological space.
