Study On Spatial Control Of Jiaozhou Bay Coastal Zone Based On Ecosystem Services

Coastal zone,as an important area connecting land and coastal zone,has abundant resources and high ecological value.It has become a research hotspot in recent years.With the increasing frequency of human activities in coastal zone,space control,as an important means of protecting coastal zone ecology and resources and promoting sustainable development,is attracting the attention of scholars from all walks of life.In this paper,Jiaozhou Bay coastal zone is taken as the research area.From the perspective of land and sea co-ordination,through a large number of literature research and field survey data collection and collation,based on the concept of ecosystem services,through the analysis and comparison of domestic and foreign coastal zone planning and management cases,drawing on its experience and combining the characteristics of resources and environment and social and economic development needs of Qingdao City,using GIS and In VEST model,Quantitative analysis and qualitative analysis are used to divide the coastal zone of Jiaozhou Bay into space control areas,and land space control and optimization policies are put forward to provide reference for the coastal zone space control of other coastal areas in China.The main body of the article can be divided into three parts:The first part is the collation and integration of the related theories of ecosystem services and coastal space control.It expounds the relationship between ecosystem services and coastal space control,and puts forward the principles of coastal space control based on ecosystem services,which are the principles of land-sea integration,coexistence of compulsion and guidance,and ecological priority.The second part is the construction of the index system.The quantitative assessment methods and evaluation indicators of ecosystem services are selected,and the evaluation system of coastal space control based on In VEST model is constructed.Finally,the index system of coastal space control based on ecosystem services is formed.The third part takes Jiaozhou Bay Coastal Zone as the support of specific cases.Based on the analysis of the general situation of Jiaozhou Bay Coastal Zone and the present situation of land use,the index system of the preceding part is applied in practice,and the planning of Jiaozhou Bay Coastal Zone Space Control is divided,and compared with the existing relevant planning,the policy of Coastal Zone Space Control is further put forward.
