中文摘要	本文通过2000、2008年及2018年3期Landsat系列数据,利用主成分分析绿度、湿度、干度、热度构建遥感生态指数(RSEI),同时采用标准差椭圆及不同生态等级的重心,对干旱区城镇哈密市伊州区的生态质量进行遥感动态监测,并分析生态质量的空间扩展。结果表明:哈密市伊州区遥感生态指数均值从0.22、0.31上升到0.40,呈现出上升趋势,生态质量总体转好,但生态质量水平较低;生态环境变好的区域集中在伊州区城区的周围,呈环形分布 ,生态变差的区域主要在北部的东天山南坡地带以及城区的西南部未开发的戈壁;根据标准差椭圆及不同生态等级重心的变化得到,伊州区生态质量较好的区域在空间上呈现出由北向南扩展,总体生态较好区域从2000 2018年均呈东南―西北走向。
英文摘要	Based on Landsat series data from 2000,2008,and 2018,this paper constructs a remote sensing ecological index using principal component analysis of green degree,humidity,dryness,and heat degree.At the same time,it uses the standard deviation ellipse and the center of gravity of different ecological levels to carry out monitoring by dynamic remote sensing of the ecological quality of Yizhou District,Hami City,an arid area,and analyzes the spatial expansion of the ecological quality.The results show that the average value of the remote sensing ecological index in Yizhou District of Hami City rose from 0.22 and 0.31 to 0.40,showing an upward trend.The overall ecological quality was better,but the level of ecological quality was lower.Areas with a better ecological environment are concentrated around the urban area of Yizhou District in a circular distribution.Areas with a worse ecological environment are mainly on the southern slope of East Tianshan Mountain in the north and the undeveloped area in the southwest of the urban area.According to the standard deviation ellipse and the change in the center of gravity at different ecological levels,the area with better ecological quality in Yizhou District is expanding from north to south,and the area with better overall ecological quality expanded from 2000 to 2018 with a southeast-northwest trend.
