Study On Ecosystem Services Value Assessment And Eco-compensation In Dashanbao Black-necked Crane Nature Reserve

The construction of nature reserve is faced with the conflicts between protection and development.Based on the support of spatial information technology,based on the remote sensing data,field survey,and literature research,the ecosystem service value of Yunnan Dashanbao Black-necked Crane Nature Reserve wasinclusively assessed.The value of ecosystem services were analysed by market value method and substitute market value method,result reference method and shadow engineering method categorized as production,soil conservation,water protection,air clearance,carbon fixation,wildlife habitat,entertainment,and cultural and scientific value.The total value of the ecosystem services in the nature reserve was 59.20 million yuan per year,and it was taken as as the scientific basis for ecological compensation.We analyzed the factors that influenced the ecological compensation standard,such as the actual economic loss of the local residents,compensatory willingness of the residents,the national policy,and the population size of black-necked cranes.The ecosystem service value of unit area was set as the maximum of ecological compensation,and the actual loss of local residents as the minimum of ecological compensation.The current ecological compensation standard of the protected area was estimated as 1428 yuan/mu.
