摘　　要：本文选取绿度(NDMVI)、湿度(Wet)、石漠化(RDI)和热度(LST)4个指数,构建了改进型遥感生态指数(IRSEI),以实现县域岩溶地区的生态环境质量评价。基于2003与2023年的县域尺度遥感影像与其他地理信息数据,通过若干方面定量对比IRSEI与RSEI指数。结果表明,IRSEI包含了更丰富的山地植被与石漠化状况信息,能够更好地表征和评价岩溶地区生态环境质量,适合作为岩溶地区生态环境质量评价的定量指标。研究区在2003—2023年间,生态环境质量改善和退化情况均有发生,但生态环境质量总体下降了7.46%,生态等级由良变为中等。从空间分布来看,罗平县研究区生态质量差的区域主要分布在北部,生态环境质量优的区域主要分布在中部。This paper selects four indices,including greenness(NDMVI),wetness(Wet),rocky desertification(RDI),and heat(LST),to construct an improved remote sensing ecological index(IRSEI)to evaluate the ecological environment quality of county karst areas.Based on county-scale remote sensing images and other geographical information data from^(2)003 and 2023,IRSEI and RSEI are quantitatively compared in several aspects.The results show that IRSEI contains richer information on mountain vegetation and rocky desertification conditions and can better characterize and evaluate the ecological environment quality of karst areas.And IRSEI is suitable as a quantitative indicator for the ecological environment quality evaluation of karst areas.In the study area of Luoping County,both improvement and degradation of ecological environment quality occurred between 2003 and 2023,but the overall ecological environment quality dropped by 7.46%,and the ecological grade changed from good to medium.From the perspective of spatial distribution,the areas with poor ecological quality in karst areas of Luoping County are mainly distributed in the north,and the areas with excellent ecological environment quality are mainly distributed in the central part.
