合理测算生态补偿资金数量及其分配方式是生态补偿研究的重点与难点。以南水北调中线工程水源区为例,在全面评估水源区生态服务价值的基础上,综合考虑区域经济发展水平和调入水量等因素,估算生态系统服务价值调节系数,尝试性地研究了水源区生态补偿资金数量及分配方式。结果表明:2014年水源区生态服务价值总量为3 225.97亿元,比2006年增加159.45亿元;中央政府承担水源区生态补偿资金量为18.8亿元,河南、河北、天津和北京等省市承担生态补偿资金量分别为11.28亿元、10.43亿元、3.1亿元和3.38亿元;陕西、湖北、河南和四川等4省水源地分配到的生态补偿资金数量分别为30.4亿元、9.15亿元、5.86亿元和1.56亿元。
Reasonable calculation of ecological compensation funds and their distribution is the focus of ecological compensation research and difficulties. Taking the water source area of the middle route of South-to-North Water Diversion Project as an example, on the basis of comprehensively evaluating the ecological service value of the water source area and considering factors such as regional economic development level and water transfer, the ecosystem service value adjustment coefficient is estimated, Compensation funds and distribution methods. The results showed that in 2014, the total value of ecological services in the water source area was 322.57 billion yuan, an increase of 15.945 billion yuan over 2006. The central government undertook the ecological compensation fund of water sources area at 1.88 billion yuan, including Henan, Hebei, Tianjin and Beijing The amount of funds for ecological compensation allocated to the four water sources in Shaanxi, Hubei, Henan and Sichuan was 3.04 billion yuan, respectively, and the number of funds for ecological compensation was 1.128 billion yuan, 1.043 billion yuan, 3.1 billion yuan and 3.38 billion yuan respectively, Yuan, 586 million yuan and 156 million yuan.
