摘要
文章以滁州市自然生态环境监测为例,利用10 m的哨兵2A数据和Landsat 8数据,计算出植被指数、湿度分量、地表温度和土壤指数来作为绿度、湿度、温度和干度指标,并进行归一化处理。采用主成分变换法集成各个生态指标,构建遥感生态指数,指数数值越大代表生态环境越好。滁州市自然生态环境RSEI指数主要集中在0.2~0.8之间,且在0.6~0.8区间居多,认为该指数可客观合理地反映研究区域生态环境质量。
Taking the monitoring of natural ecological environment in Chuzhou City as an example,the article used 10 m Sentinel 2A data and Landsat 8 data to calculate vegetation index,humidity component,surface temperature and soil index as indicators of greenness,humidity,temperature and dryness,and normalize them.The method of principal component transformation was used to integrate various ecological indicators to construct the Remote Sensing Ecological Index(RSEI).The larger the RSEI index value,the better the ecological environment.It was believed that the RSEI index of the natural ecological environment in Chuzhou was mainly concentrated in the range of 0.2 to 0.8,with a large proportion in the range of 0.6 to 0.8,which objectively and reasonably represented the quality of the ecological environment in the study area.
