摘　　要：针对生态保护红线区域生态变化质量问题,以盐城湿地珍禽国家级自然保护区核心区为例,采用2010年、2015年、2019年的Landsat TM/OLI影像为数据源,利用主成分分析法构建包含绿度、湿度、热度、干度等多指标的遥感生态指数RSEI,监测和评价其生态环境质量。研究表明(1)RSEI获取方便,可综合反映研究区的生态环境质量变化;(2)2010年、2015年和2019年的RSEI分别为0.7137、0.7526和0.7684,研究区生态环境质量逐步提升;(3)区域生态环境质量总体保持优等不变,RSEI变好、不变、变差区域分别占21.37%、66.61%、12.02%。In order to study the quality of ecological change in ecological protection red line area,the core area of Yancheng wetland rare birds national nature reserve was taken as an example,the Landsat TM/OLI images of 2010,2015 and 2019 as data sources,used principal component analysis construct the remote sensing ecological index,which contained many indexes such as the greenness、wetness、dryness、heat,and the ecological environment quality of the protected area was monitored and evaluated.The results show that:(1)RSEI is easy to obtain and can comprehensively reflect the change of ecological environment quality in the research area;(2)The RSEI in 2010,2015 and 2019 were 0.7137,0.7526 and 0.7684,and the ecological environment quality of the research area is gradually improved;(3)The overall ecological environment quality of the region remain excellent,with the RSEI improving,unchanged and deteriorating regions accounting for 21.37%,66.61%and 12.02%,respectively.
