摘　　要：水土保持生态补偿是生态补偿在水土保持领域的具体实践,是预防和治理水土流失的重要举措。为有效识别水土保持生态补偿费支付的优先区域,优化专项资金使用,选取洞庭湖生态经济区为研究对象,运用InVEST模型,结合市场价值法、机会成本法和影子工程法,对水土保持价值进行评估;根据水土保持价值、经济发展水平和生态系统脆弱性的综合状况,从县(市、区)角度划分水土保持生态补偿的空间区域。研究结果表明:(1)2015年洞庭湖生态经济区水土保持价值高达641.9887亿元,其空间分布差异明显,表现为东西部价值高,中部低;(2)以生态补偿优先级划分的1级和2级区多属于生态输出与经济受损区,而3级区则属于生态消费和经济受益区;(3)在生态补偿优先级基础上考虑生态系统脆弱性,可将洞庭湖生态经济区划分为优先补偿区、次级补偿区、一般补偿区和潜在补偿区。优先补偿区和次级补偿区是生态补偿的主要区域,应把有限的补偿资金优先或更多地分配到上述区域,这对提高区域水土保持服务和经济发展水平以及防治水土流失有重要意义。Being important to prevent and control soil erosion,ecological compensation for soil and water conservation is a specific practice of ecological compensation in this field.In order to effectively identify the priority areas for the payment of soil and water conservation compensation and optimize the use of special funds,the Dongting Lake Eco-economic Zone was taken as the research object,and the InVEST Model combined with the market value method,opportunity cost method and shadow engineering method were used to evaluate the value of soil and water conservation.According to the comprehensive status of soil and water conservation value,economic development level and ecological system vulnerability,the spatial area of soil and water conservation ecological compensation was divided on the scale of counties(cities,districts).The research results show that:(1)In 2015,the value of soil and water conservation in the Dongting Lake Eco-economic Zone was as high as 64.19887 billion yuan.The spatial distribution of soil and water conservation value were significantly different,characterized by high value in the east and west and low in the middle;(2)The level 1 and level 2 areas classified by the Ecological Compensation Priority Sequence are mostly with ecological output and economic damage,while the level 3 areas are with ecological consumption and economic benefit;(3)Based on the Ecological Compensation Priority Sequence,considering the fragility of the ecosystem,the Dongting Lake Eco-economic Zone can be divided into priority compensation area,secondary compensation area,general compensation area and potential compensation area.The limited compensation funds should be mainly allocated to the priority compensation areas and secondary compensation areas,which is of great significance for improving regional water and soil conservation services and economic development,as well as preventing soil erosion.
