新疆地区水土保持功能价值评估方法及生态服务价值估算

Evaluating Functions of Soil and Water Conservation and Ecosystem Service in Xinjiang Uygur Autonomous Region

随着新疆维吾尔自治区经济社会的不断发展及资源开发力度的加大,一些生态补偿标准已不适应新的形势和需要。迫切需要重新制定新疆维吾尔自治区能源开发水土流失补偿费征收标准和使用管理办法,促进经济社会发展同水土保持生态环境相协调。结合新疆维吾尔自治区水土保持行政监督部门的实际工作,简要叙述了水土保持补偿的内涵与外延,分析了新疆维吾尔自治区水土流失现状及危害,比较了生态服务价值各种评估方法,并对新疆维吾尔自治区水土保持功能生态服务价值进行了估算,得出新疆维吾尔自治区水土保持功能生态服务价值为1 231亿元/a,也可据此为煤炭、石油和天然气的水土流失补偿费制定提供参考。

With rapid development of the resources and social economy in Xinjiang Uygur Autonomous Region,some provisions,especially the compensation standard,are not suitable for the new situation and needs.Therefore,we should explore further in practice and establish new collecting standards of soil and water compensation in Xinjiang region to promote the harmonization between economic and social development and ecological environment associated with soil and water conservation.Incorporating the practices of soil and water conservation administrative divisions,this study described the connotation and denotation of soil and water conservation compensation,analyzed the present status and risks of soil erosion in the region,compared the approaches to estimating the values of ecological service function,and especially assessed the soil and water conservation function values of Xinjiang region.By calculation,the soil and water conservation function value in Xinjiang region was approximately 123.1 billion/a.The result could be used as reference to determine soil and water loss compensation in coal,oil and natural gas development projects.
