基于生态系统服务价值的区域生态补偿研究——以辽宁省为例

对辽宁省各地级市和典型城市县(市)的生态系统服务价值和生态补偿优先级(ECPS)进行了计算,从市和县两个空间尺度分析了辽宁省开展区域生态补偿的优先领域和补偿机制。结果表明:在辽宁省14个地级市中朝阳市应该率先获得生态补偿;对沈阳、大连、抚顺、朝阳4个典型城市中的各县区进行生态补偿优先级核算,4个城市中市区的补偿优先级均为最低,说明市区是生态系统服务的输入和受益地区,而周围县市的补偿优先级较高,是"生态输出"地区,其中新宾县的生态补偿优先级最高,应优先享受生态补偿。

Regional eco-compensation based on ecosystem service assessment---a case study of Liaoning Province

The ecosystem service value and the ECPS of different cities and counties of Liaoning Province were calculated, and the priority areas and mechanism of regional ecological compensation in Liaoning Province were analyzed at two spatial scales： the prefecture-level city spatial scale and the county spatial scale . The results showed that on the prefecture-level city scale, among all the 14 cities of Liaoning Province, Chaoyang should first get compensation. For the county scale, the ECPS of all the counties in the four typical cities （Shenyang, Dalian, Fushun and Chaoyang）of Liaoning Province was calculated. Of the four cities, a common result was that the urban area of a city had the lowest priority level among all the counties of that city, indicating that the urban area benefited from the ecosystem service value of the counties around it and should provide compensation . As a typical area, the Xinbin county of Fushun city had the highest priority level and should get the first compensation .
