摘要生态文明示范区是推进区域环境保护和社会发展协同共赢的重要平台和有效载体,包括国家生态文明建设示范区和“绿水青山就是金山银山”实践创新基地(简称“两山”实践创新基地),分别着力于构建以产业生态化和生态产业化为主体的生态经济体系、探索生态产品价值实现路径和模式,特别是在快速城市化地区。以长江三角洲(简称长三角)区域77个生态文明建设示范区和22个“两山”实践创新基地为对象,综合利用土地利用、夜间灯光和MODIS数据,分别构建遥感生态指数(remote sensing ecological index,RSEI)和综合夜间灯光指数(compoun-ded night light index,CNLI)代表生态环境质量和城市化水平,并采用空间叠加分析方法和耦合协调度模型探析长三角生态文明示范区建设水平和时空差异性。结果表明:(1)生态文明示范区在长三角区域分布具有不均衡性,生态文明建设示范区分布较为集中且以平原地形为主,“两山”实践创新基地分布较分散,以山地地形为主。(2)生态文明示范区生态用地面积占比超70%,具有较好的生态环境基础,“两山”实践创新基地RSEI指数高于生态文明建设示范区,生态环境质量优越,但更具脆弱性。(3)生态文明建设示范区CNLI指数及其增速均大于“两山”实践创新基地,具有更高的城市化水平和发展速度。(4)2017—2021年,生态文明建设示范区和“两山”实践创新基地RSEI和CNLI指数的耦合协调度呈现不断增加趋势,平均增幅分别为1055%和890%,生态文明建设取得一定成效,其中江浙两省交界处耦合协调度最高。 The ecological civilization demonstration area includes the national ecological civilization construction demon-stration area and the“Lucid Waters and Lush Mountains Are Invaluable Assets(as Two Mountains)”practice and innova-tion base,which focuses on the developing of an ecological economic system with industrial ecology and ecological industri-alization as the mainstay,explores the path and model of realization of ecological product value,especially in rapidly ur-banized areas.Taking 77 ecological civilization construction demonstration areas and 22“Two Mountains”practice and in-novation bases in the Yangtze River Delta(YRD)as the objects,the author utilized land use products,VIIRS,and MO-DIS data to construct remote sensing ecological index(RSEI)and compounded night light index(CNLI)to represent the ecological environment quality and urbanization level,respectively,and explored the level and spatiotemporal variability of ecological civilization demonstration construction in the YRD by using spatial superposition analysis and coupling coordina-tion degree model.The results show as follow:(1)The distribution of ecological civilization demonstration area in the YRD is uneven,among which,the distribution of ecological civilization construction demonstration areas is more concen-trated and dominated by plain terrain,while the“Two Mountains”practice and innovation bases are more dispersed and dominated by mountainous terrain.(2)The ecological land area of the ecological civilization demonstration area exceeds 70%and has a good environment foundation,among which the RSEI index of the“Two Mountains”practice and innova-tion base is higher than that of the ecological civilization construction demonstration area,and the ecological environment quality is superior,but it is more fragile.(3)The CNLI and its growth rate of the ecological civilization construction dem-onstration areas are higher than those of the“Two Mountains”practice and innovation bases,which has a higher urbaniza-tion level and develo
