摘　　要：为了探究中小城市不透水面演变对城市生态环境质量的影响,基于2000-2020年Landsat遥感影影像,采用不透水面指数(NDISI)和遥感生态评价指数(RSEI)监测与分析淮安市不透水面对生态环境的影响.结果表明,2000-2020年淮安市不透水面面积显著增加,以蔓延式、跨越式发展模式由城市中心逐渐向周边扩张,年均增长率为8.5%,2008-2012年期间增长最快.不透水面丰度空间上由城市中心向周边逐渐递减,年均值从2000年的0.261增加至2020年的0.330.研究期生态环境质量有所改善,生态环境质量等级中较差和一般的面积减少,而良好和优等级分别增加了1677.01 km^(2)和672.1 km^(2).NDISI丰度与城市生态环境质量负相关,研究期内不透水面与生态环境质量的联系越来越密切.In order to investigate the impact of impervious surface evolution on urban ecological environment quality in small and medium-sized cities.Based on Landsat images from 2000 to 2020,this paper monitors and analyzes the impact of impervious surface on the ecological environment in Huai'an City using the impervious surface index(NDISI)and remote sensing ecological evaluation index(RSEI).The results showed that:(1)the area of impervious surface in Huai'an City increased significantly from 2000 to 2020,gradually expanding from the city center to the periphery in a spreading and leapfrog development pattern,with an average annual growth rate of 8.5%,and the fastest growth during the period of 2008-2012.The abundance of impervious surface spatially decreased gradually from the urban center to the periphery,with the average annual value increasing from 0.261 in 2000 to 0.330 in 2020.(2)The ecological environment quality improved during the study period,with the area of poor and average ecological environment quality grades decreasing,while the good and excellent grades increased by 1,677.01 km2 and 672.1 km2,respectively.(3)NDISI abundance was negatively correlated with urban ecological environment quality,and impervious surfaces were increasingly associated with ecological environment quality during the study period.
