皖江城市带是长三角区域的腹地和生态屏障,在长三角区域生态环境保护中起着关键作用。本文基于长三角生态绿色一体化的背景,运用生态系统服务价值评价方法,测算2015~2020年长三角区域的生态服务价值,确定皖江城市带8个城市的生态补偿优先级和生态补偿标准。结果显示,2020年长三角区域的生态服务价值为28150.21亿元,比2015年下降5.14%。其中,皖江城市带降幅最小,为3.04%。在长三角区域中,池州市、宣城市、安庆市、铜陵市和滁州市的生态优先级和生态补偿金额最高。马鞍山市和芜湖市的位次也排在前列,只有合肥市处在中等水平。最后,提出在长三角区域生态环境保护协作小组的指导下,从产业协作、科技协作和金融协作三方面开展对口协作式生态补偿,推动皖江城市带的生态环境保护工作。The urban belt of Wanjiang River is the hinterland and ecological barrier of the Yangtze River Delta region, playing a crucial role in the ecological environment protection of the Yangtze River Delta. Based on the background of the ecological and green integration of the Yangtze River Delta and the ecosystem service value evaluation method, this paper calculates the ecological service value of the Yangtze River Delta region from 2015 to 2020 and determines the priority and standards of ecological compensation for the eight cities in the urban belt of Wanjiang River. The results show that the ecological service value of the Yangtze River Delta region in 2020 was 28150.21 billion yuan, a decrease of 5.14% compared with 2015. Among them, the Wanjiang River urban belt had the smallest decline, at 3.04%. In the Yangtze River Delta region, Chizhou City, Xuancheng City, Anqing City, Tongling City and Chuzhou City had the highest ecological priority and ecological compensation amount. Ma’anshan City and Wuhu City also ranked among the top, while Hefei City was at a medium level. Finally, under the guidance of the Yangtze River Delta regional ecological and environmental protection cooperation group, it is proposed to carry out the matching cooperative ecological compensation from the three aspects of industrial cooperation, scientific and technological cooperation and financial cooperation, so as to promote the ecological and environmental protection work in the urban belt of Wanjiang River.
