Study Of Wetland Ecosystem Protection And Management Policies In Beijing

Wetland ecosystem and resources in Beijing have huge service function,and are very important in maintain balance of ecosystem and urban ecological security.Because of change of globe climate and increasing of population,area of Beijing wetlands is decreasing sharply,and water is polluted heavily.Service function of wetland ecosystem is degrading by a large margin. The objective of this study is change the state that wetland ecosystem has degreaded in Beijing, and abate decrease of the area of natural wetland,maintain health and integrity for wetland ecosystem in Beijing,and achieve the goals along with＜The Beijing Action Plan for Wetland Protection.Analyse for the cause of the wetland ecosystem degreaded in Beijing,which are the basis and starting point for this study.Literature Research,Ecosystem Approach,Analytic Hi-erarchy Process are adopted in this study.The main focus of this study is to the value assessment of wetland ecosystem service function in Beijing,economic analysis of degeneration reason of wetland ecosystem in Beijing,study on regime of wetland ecosystem management in Beijing,study on legislation supporting system of wetland ecosystem management,study on ethical supporting system of wetland ecosystem management and study on countermeasure of wetland ecosystem protection and management.The main results are as following:1.The area and quality of Beijing wetland ecosystem are suffering from serious damage, and wetland ecosystem functions are weaken in Beijing,the risk degreed for ecosystem safe is inceaseing.2.Because of temperature rising,precipitation decreasing,market and government failure, population increasing and land use changing,wetland ecosystems have degreaded in Beijing.3.Wetland has lots of important service function,like production supply,regulation function, cultural function and supporting function,which are valued￥100 billions.4.The value of wetland ecosystem service function is decreasing in Beijing.Disturbance has overed the capacity that wetland ecosystem can support nearby ten years. 5.At preaset,it is necessary that perfect and optimize the management system in Beijing because there are the problems,which the responsibility can not consistant with the benefit, management institution is not right,management measure is lacking in wetland management sector Beijing.6.It is necessary and feasible those establish the special rule of law for wetland in Beijing bases on the study on the requirement for national environmental protect policys and government sector,standing policys and law basis and citizen awareness.7.Tt is importment that set corrective ethic view.8.Beijing wetland ecosystem protection and sustainable management may be implemented by the follow measures:(1) Value assessment of wetland ecosystem service function should be more exact and comprehensive.(2) Regime of wetland protection should be optimized.(3) Legislation system of wetland protection and management should be established.(4) Ethnics system of wetland ecosystem management should be established.(5) Capability of wetland ecological water use should be enhanced.(6) Establishment of wetland nature reserves should be enhanced.(7) Wetland resources should be used wisely.(8) Science research of wetland should be developed deeply.
