摘要 生态系统服务功能是实施区域生态补偿最直接的依据。基于修正后的生态系统服务价值核算方法,对重庆市生态系统服务价值、生态补偿优先级及生态补偿额进行了核算,结果表明:1)重庆市2019年生态系统服务总价值8898.99亿元,水文调节和气候调节是最主要的生态系统服务价值类型;空间上,渝东北三峡库区城镇群生态系统服务价值占比达到42.72%,高于渝东南武陵山城镇群(33.96%)和主城都市区(23.32%),生态系统服务价值较低区县均位于中心城区。2)渝东北、渝东南地区为主要“生态服务输出”区域,应获得生态补偿,主城都市区为主要“生态服务消费”区域,应支付生态补偿。3)全市优先和次级生态补偿区主要包括城口、巫溪、丰都、奉节、开州、南川、彭水、石柱、巫山、武隆、秀山、酉阳、云阳共13个区县,应获得生态补偿额485.04亿元,其中酉阳、巫溪、城口占总补偿额度的35.1%。 Ecosystem service function is the most direct basis for regional ecological compensation.Based on the improved ESV estimation method,this paper estimated the ESV,ecological compensation priority and ecological compensation amount of Chongqing in 2019.The results are follows:1)The total value of ecosystem services in Chongqing was 8898.99 billion CNY in 2019,and the value of forest ecosystem accounts for the highest proportion(73.3%).Hydrological regulation and climate regulation are the main service types in the ecosystem.Spatially,the ESV of the urban clusters of Three Gorges Reservoir in northeast Chongqing is the highest,accounting for 42.72%,while that of the central urban area is relatively low.2)The northeast and southeast of Chongqing which have higher priority of ecological compensation correspond to the region of ecosystem service outputting,and thus should first get compensation,while the main urban area of Chongqing with lower priority of ecological compensation is ecological service consumption areas and should provide compensation.3)The priority and secondary ecological compensation area mainly includes Chengkou,Wuxi,Fengdu,Fengjie,Kaizhou,Nanchuan,Pengshui,Shizhu,Wushan,Wulong,Xiushan,Youyang,Yunyang.The ecological compensation amount should be 485.04 billion CNY,of which Youyang,Wuxi and Chengkou account for 35.1%.
