摘要
文章基于2005—2020年长江干流11个省份的土地利用数据,采用水足迹法引入自身生态消费价值系数,结合生态系统服务价值法,通过考量生态价值的供给与消费,探究了不同省份的生态系统服务外溢价值;并在确定流域横向生态补偿标准的基础上,引入比较生态辐射力模型,从生态系统服务流的角度优化了长江干流各省份横向生态补偿资金分配方案。结果表明:①2005—2020年长江干流的生态系统服务价值先缓慢下降后陡增,总体上涨幅为3.16%。②长江干流的自身生态消费价值呈倒“U”型变化,但总体上略有增长,且呈现从西向东逐渐递增的趋势。③研究期间长江干流整体生态系统服务处于外溢状态,补偿标准从高到低依次为西藏、青海、四川、云南、江西、湖南、重庆、湖北、安徽、上海和江苏。④江苏需支付占比超过总额的60%,是长江干流横向生态补偿资金的主要来源;安徽与上海分别在2005和2015年、2010和2020年承担的生态补偿责任最少。⑤西藏获得的补偿资金占比超过总额的50%,是长江干流横向生态补偿的主要受偿对象;安徽在2010和2020年获得补偿最少;2005和2015年受偿最低的是湖北和重庆,占比均不足0.7%。
Based on the land use data of 11 provincial-level regions of the Yangtze River mainstream from 2005 to 2020,this study adopts the water footprint method to introduce self eco-consumption value coefficient,combines with the ecosystem services value method,and considers the supply and consumption of ecological value to explore the spillover value of ecosystem services in different provinces.Based on the determination of horizontal ecological compensation(HEC for short)standards,a comparative ecological radiation force model is introduced to optimize HEC funds allocation scheme for Il provinces in the Yangtze River mainstream from the perspective of ecosystem services flow.The results show that:1)The ecosystem service value of the Yangtze River mainstream declines slowly at first and then increases steeply from 2005 to 2020,with an overall increase of 3.16%.2)The value of ecological consumption in the Yangtze River mainstream shows an inverted-U shape,but increases slightly in general,and shows a trend of gradual growth from the west of the Yangtze River mainstream to the east of the Yangtze River mainstream.3)The overall ecosystem services of the Yangtze River mainstream are in a spillover state during the study period.The compensation standards,in descending order,are Xizang,Qinghai,Sichuan,Yunnan,Jiangxi,Hunan,Chongqing,Hubei,Anhui,Shanghai and Jiangsu.4)Jiangsu is required to pay more than 60%of the total,and is the main source of HEC funds in the Yangtze River mainstream.Anhui and Shanghai were the least responsible for compensation in 2005 and 2015,2010 and 2020,respectively.5)Xizang receives more than 50%of the total compensation funds,and is the main recipient of HEC.Anhui receives the least compensation in 2010 and 2020.Hubei and Chongqing receive the least compensation in 2005 and 2015,accounting for less than 0.7%.
