摘　　要：气候灾害易影响生态环境,传统的遥感生态指数(RSEI)缺乏气候因素影响生态质量的研究,本研究引入气象因子并优化了生态因子的选择,更加综合全面评价区域内的生态环境质量。使用主成分分析法构建新遥感生态指数(NRSEI),对各因子及多因子交互分析。结果表明,NRSEI较RSEI各因子在第1主成分贡献率均值提升12.53%,并且NRSEI与各因子相关性为高度相关,3 a均值为0.853。分析了2013-2020年阜新市生态环境的变化特点和原因,并利用NRSEI对研究区域的生态环境质量进行动态监测和评估,总体来看,2013-2020年阜新市生态环境状况变好,对于阜新市与NRSEI相关性最高的单个因子是湿度因子,因此阜新市相关部门应注重对河流、湖泊和湿地的保护,减少建筑开发,以改善城市的环境质量。Climate disaster can easily affect biological environment.The traditional remote sensing ecological index(RSEI)lacks considering the influence of climatic factors on ecological quality.Taking Fuxin City as an example,this study introduced meteorological factors and optimized the selection of ecological factors to more comprehensively evaluate the ecological quality in the region.The new remote sensing ecological index(NRSEI)was constructed using principal component analysis,and the factors and multi-factor interactions were analyzed.The results showed that the NRSEI improved the mean value of 12.53%compared to the first principal component contribution of each factor of the RSEI,and the correlation between the NRSEI and each factor was highly correlated,with a three-year mean value of 0.853.This study also analyzed the characteristics and causes of the changes in the ecological environment of Fuxin City from^(2)013 to 2020,and used the NRSEI to dynamically monitor and assess the ecological environment quality in the study area.In general,the ecological environment of Fuxin City became better from^(2)013-2020.The single factor with the highest correlation with NRSEI was the humidity factor.It is suggested that the relevant departments of the municipality should focus on the protections of rivers,lakes and wetlands and reduce the building development in order to improve the environmental quality of the city.
