摘　　要：利用遥感技术监测生态环境质量对预防生态环境恶化具有重要作用。精确衡量地区的生态信息,认清当地生态环境质量现状和保护生态环境具有指导性意义。文中在遥感生态指数(RSEI)基础上结合人口密度、土地利用数据和2013年、2018年和2023年高分辨率Landsat影像数据建立改进型遥感生态指数(IRSEI)作为生态环境质量评价指标,结果表明:该指标与GDP、人口密度呈较强的负相关性,2013—2023年烟台生态环境质量持续下降,2013年、2018年、2023年IRSEI均值分别为0.2735、0.269、0.231。2013—2023年大部分区域生态环境质量基本保持不变;生态环境质量略微变差的土地面积占总面积约34%。生态环境质量变差与城市扩张、人口增长等人为因素具有密切联系,且呈现相关性,可见人为活动对生态环境质量影响较大。The use of remote sensing technology to monitor ecological environment quality plays an important role in preventing ecological environment deterioration.Accurately measuring the ecological information of a region,recognizing the current status of local ecological environment quality,and protecting the ecological environment have guiding significance.Based on the Remote Sensing Ecological Index(RSEI)and combined with population density,land use data,and high-resolution Landsat image data from 2013,2018,and 2023,an improved Remote Sensing Ecological Index(IRSEI)was established as an ecological environment quality evaluation index.The results showed that this index had a strong negative correlation with GDP and population density.From 2013 to 2023,the ecological environment quality in Yantai continued to decline,with average IRSEI values of 0.2735,0.269,and 0.231 in 2013,2018,and 2023,respectively.The ecological quality of most regions will remain basically unchanged from 2013 to 2023;The land area with slightly worse ecological quality level accounts for about 34%of the total area.The deterioration of ecological quality is closely related to human factors such as urban expansion and population growth,and shows a correlation,indicating that human activities have a significant impact on the quality of the ecological environment.
