Study On Supervision And Management Technology System Of Uninhabited Island Eco-development

As the development of marine economics and implementation of marine powerful nationstrategy, the utilization of uninhabited island has been gradually put on the strategy.Coordinating the relationship between utilization, ecological environment, economics, andsociety, and exploring sustainable development measurement are the aims of island scienceresearch. Also, it is one of the research directions in The12th Five-Year National MarineScience and Technology Development Plan.This study comprehensively applies the theories and methods of ecology, eco-economics,environmental science, resource management and so on, combined with theoretical researchand case analysis, to study the supervision and management technology system of uninhabitedisland eco-development from the directions of island ecological system vulnerability,comprehensive evaluation of eco-development, organizational system and legal liabilitysystem. Then, it is applied to three islands in Tangshan Bay. The mainly results are:(1) The analyses of advantages, disadvantages and problems in the development ofuninhabited islands show that an efficient way for uninhabited islands sustainabledevelopment is to implement eco-development.In addition, the feasibility of eco-developmentfor uninhabited islands is investigated and methods from direct and indirect means are furtherdiscussed.(2) The connotation of uninhabited island eco-development from the direction of ecosystemis analyzed. the difference between natural ecosystem and complex ecosystem of uninhabitedisland is a compared. Detailed analyses of the threat from development to ecosystem, theinteraction between ecosystem and economic system, and the function of uninhabited islandcomplex ecosystem are conducted. Industrialization and industrial structure adjustment,mineral resources, investment and policy are the driving forces of uninhabited islands. Thebraking forces of uninhabited island include water resources, land resources, topography and ecological environment.(3) We analyze supervision and management technology system of uninhabited islandeco-development from the directions of organizational system, legal liability system andtechnical framework, combe organizational system, clarify the legal responsibilities and builda single uninhabited island supervision technology framework. The framework of islandsupervision consits of subject, content, methods and information feedback system.(4) Resilience and disturbance are determining factors in the concept and connotation ofuninhabited island ecosystem vulnerability. A two-level assessment method for uninhabitedisland ecosystem vulnerability is constructed with first-level and second-level assessmentsbased on elastic force and disturbing forces of uninhabited island ecosystem vulnerability,respectively.(5) An uninhabited island eco-development assessment index system and evaluation modelis built, consisting of ecological disruption, eco-development, development efficiency andintensive and economical aspects. It also includes status assessment, tendency assessment andstability assessment of uninhabited island eco-development.(6) Tangshan Bay Three Islands (Yuetuo Island, Dawanggang Island and Shijiutuo Island)eco-development supervision system has been built, and The eco-development level isassessed. Yuetuo Island, Dawanggang Island and Shijiutuo Island eco-development score are0.300,0.303and0.440, these show Tangshan Bay Three Islands eco-development level isRelatively high.
