Research Of Marine Ecological Environment And Ecosystem Services In Shuangtaizi Estuary

Shuangtaizi estuary receives great impact from human activities, and sustainable development of the bay ecosystem has become a major concern of both scientists and the local government. Thus,a systematic investigation of the ecological factors and analysis of the data is obviously necessary for a better understanding of the ecosystem and subsequent measures.Through 2008 investigating status, such as the Shuangtaizi estuary and environmental quality status, the water quality, living resources, dreariness, biological quality in the sea area, etc., has found the main ocean ecological problems. This paper not only established Shuangtaizi estuary ecological monitoring of ecosystem health assessment index system through the application of AHP, but also calculated health index. At last, it analyzed the marine ecology services functional status in this case.chooses a lot of appraisal factors from the three respects of environment, biology community and ecosystem function, adopts the analytic approach to confirm the weight of each appraisal factor, sets up the estuary ecosystem health composite index of the Shuangtaizi estuary, analyses the environmental health degree of the Shuangtaizi estuary and near sea area synthetically, and has anaslysed the main factor that may exert an influence on this sea area marine ecological environment.This paper includes 4-point:1,The general situation of Shuangtaizi estuary ecological monitor area was introduced, including natural resources, ecosystem characters ect.2,This paper established Shuangtaizi estuary ecological monitoring of ecosystem health assessment index system by the data of 2007 and 2008.3,Shuangtaizi estuary ecological monitoring of ecosystem health assessment index were 1.054 and 1.016 in 2007 and 2008 through the application of AHP.4,This study recommend some suggestions about the management and protection of the monitor area.
