Evaluation of the ecological service of Ebinur Lake Wetland Nature Reserve

The study on value of ecosystem services is a new scientific hotspot,on the point of ecology and environmental problems,and is the major content of the sustainable development study.The social sustainable development depends radically on the sustainable development of ecosystem and ties services.So,the evaluation of the ecological service is an important measure to improve the realization that the environment is valuable.As a significant and typical inner lake in arid land,Ebinur Lake wetland is located in Bortala Prefecture of the Northwest of Xingjiang.In the past 50 years,the deteriorating ecological environment of the Ebinur Lake drainage has severely affected the local environmental qualities and economic development.Taking the Ebinur Lake Wetland Nature Reserve as a study area,this paper uses several ecological service evaluation methods,including shadow engineering,substitute expense and carbon tax law,etc,to calculate seven values of the ecosystem service function of Ebinur Lake Wetland Nature Reserve.The results show that the annual valuation of ecosystem service of research area amounts to RMB 68.65×108 Yuan,which is 0.890 6 times as more as 2007 local GDP.The paper also concludes that in order to reduce the hurt caused by the degradation of Ebinur Lake Wetland ecological system,the issue of Ebinur Lake wetland protection is not only the regional environmental issue but also the regional economic issue.
