摘要: 汉江生态经济带是我国南水北调中线工程水源区,加强其生态系统服务价值空间流转及生态补偿研究,对于推进区域生态文明建设,促进生态产品价值转化具有重要意义。采用生态系统服务价值当量因子法、生态补偿优先级指数和空间自相关分析法等,在测算生态系统服务价值的基础上,评估了汉江经济带生态补偿优先级、生态补偿额度和比较生态辐射力大小,揭示了区域生态系统服务供给状况及空间流转特征。结果表明:(1)1990~2020年汉江生态经济带各县区单位面积生态系统服务价值多年平均值在82.64~491.19万元/km2,内部空间差异大。(2)从县域尺度来看,单位面积生态系统服务价值空间集聚性呈微下降倾向,局部集聚显著。(3)研究区生态补偿总额度理论值为235.34亿元,占汉江经济带国内生产总值的0.97%,上游汉中市、安康市、商洛市、十堰市和神农架林区生态补偿总额占总补偿额度的80.97%。(4)十堰市比较生态辐射力较大,对研究区中下游城市的生态贡献度高,应建立横向生态补偿机制,推进上下游形成流域协同治理与统筹发展。总体来看,汉江生态经济带生态系统服务价值内部差异大,从生态补偿优先级角度,进行生态补偿空间识别及生态补偿额度确定是指导流域生态补偿可资借鉴的方法,也为建立横向生态补偿机制提供了理论基础和实践指导。

Abstract: Hanjiang Eco-economic Belt is the water source of the Middle Route Project of South-to-North Water Transfer in China. It is helpful for promoting the construction of regional ecological civilization and the value transformation of ecological products to strengthen the research on the spatial transfer of ecosystem service value and ecological compensation in the economic belt. The methods of ecosystem service equivalent, ecological compensation priority index and spatial autocorrelation analysis were used to evaluate ecosystem service value, the priority of ecological compensation, ecological compensation amount and comparative ecological radiation in Hanjiang Eco-economic belt. The results showed: (1) the multi-year average value of ecosystem service value per unit area of counties and districts was 826.4-4 911.9 thousand yuan/km2, with large internal spatial differences. (2) At the county level, the spatial agglomeration of ecosystem service value per unit area showed a slight downward trend, while local agglomeration was significant. (3) The theoretical value of the total ecological compensation amount was 23.534 billion yuan, accounting for 0.97% of the gross domestic product in the Hanjiang Economic Belt. In the areas of Hanzhong, Ankang, Shangluo, Shiyan, and Shennongjia Forest Area, the total ecological compensation amount accounted for 80.97% of the total compensation amount. (4) Shiyan city had a relatively large ecological radiation force and a high ecological contribution to the middle and lower reaches of the research area. Therefore, a horizontal ecological compensation mechanism should be established to promote the formation of collaborative governance and coordinated development in the upstream and downstream. Overall, there were significant internal differences in the ecosystem service value of Hanjiang Eco-economic Belt. The model of ecological compensation priority was used to identify the ecological compensation space and the determination of ecological compensation amount. The method could be used as a reference to guide the ecological compensation of the watershed, and provided theoretical basis and practical guidance for establishing a horizontal ecological compensation mechanism.
