Study On Biodiversity Investigation And Protection In The Panjin Shuangtaizi Estuary Wetland Nature Reserve

In recent years, with the whole liaohe basin accelerated of urbanization pace, serious shortage of the development land of Industry and urban, modern marine development makes many industries in the land migrate to coastal zone. Along with the large-scale development and utilization of coastal economic zone in the Liaodong bay area and upstream basin industrial park, the sea flux of various discharge of sewage surge, the load of pollutant quantity increase, make the ecological environment seriously threatened, cause the safety and risk of the ecosystem in the Shuangtaizi estuary increasingly worsening, the protection of biodiversity in the Panjin Shuangtaizi estuary nature reserve has been a new hotspot for environmentalists and the public.Coastal estuary wetland is an unique ecosystem, has the circulatory system of element, is the essence of the ocean biological life and growth in nature. Since wetlands have a good ecological regulation, especially in the regulation of river runoff, improve the environment, maintain the ecological balance and migratory habitat of migratory birds plays an important role.So this thesis is based on the survey data and the collected data in Shuangtaizi Estuary wetland, using analytic hierarchy process, selecting the system, practicality and operability evaluation index, depth studying in habitat status and the protection survey of biodiversity of the wetland ecosystem in the sea area.Based on this, I selected the index which taking into account both the direct and indirect of wetland ecosystems, making comprehensive evaluation of the biodiversity status quo in the nature reserve. According to the study on the biodiversity assessment in Shuangtaizi Estuary nature reserve, understanding the status of the wetland ecosystem function in this region, knowing the possible future trends, accordingly providing strong support for the comprehensive renovation work in the nature reserve. This paper is based on the habitat status in the wetland of nature reserve, The research contents of biodiversity protection are as follows:(1)According to field survey data and collected data, analyzed the biodiversity status in Panjin Shuangtaizi Estuary nature reserve(2)Based on the biodiversity status in Panjin Shuangtaizi Estuary nature reserve, selected six index which taking into account both the direct and indirect of ecosystems and landscape diversity, established the evaluation index system of biodiversity in Panjin Shuangtaizi Estuary nature reserve.(3)Evaluated the biodiversity of nature reserve by using analytic hierarchy process, analysis the causes of biodiversity degradation and put forward the corresponding protective measures.In a word, in view of the protection angle of biodiversity in Panjin Shuangtaizi Estuary nature reserve, the author puts forward the countermeasures of marine wetland protection and the formulation of marine environment, strictly controlling the upstream pollutant discharge into the sea, providing a new basis for the marine and wetland administrative department.
