摘要:
 以阜新市为研究区域,利用主成分分析法对影响生态环境的因素进行单因素分析和多重因素的交互作用分析。选取阜新市2007、2013年和2019年的Landsat遥感影像对湿度、绿度、干度和热度4个生态环境影响因素进行提取,并结合主成分分析将多重影响因素耦合为遥感生态指数RSEI,从而对阜新地区进行生态环境质量评价。结果表明,2007-2019年,阜新市RSEI指数总体呈上升趋势,由2007年的0.671增加到2019年的0.687,生态环境指数上升2.32%;研究区域内大部分RSEI等级为中和良的地区,面积占比提高到90.58%;总体来看,生态环境整体向好发展。对于阜新市与RSEI指数相关度最高的是干度分量,因此应重点关注干度分量中建筑指数和土壤指数协同作用对生态环境的影响。
Abstract:
 Taking Fuxin City as the research area,principal component analysis was used to analyze the single factor and multi-factor interaction which affect the ecological environment.Landsat remote sensing images of Fuxin City in 2007,2013 and 2019 were selected to extract the four ecological environment influencing factors,including humidity,greenness,dryness and heat,which were coupled into remote sensing ecological index (RSEI) by principal component analysis method to evaluate the ecological environment quality of Fuxin area.The results showed that from 2007 to 2019,the RSEI index of Fuxin City was on the rise,from 0.671 to 0.687,and the ecological environment index rose by 2.32%.The area with good and medium RSEI level increased to 90.58%.Overall,the ecological environment is becoming better.The highest correlation with RSEI index is the dryness component for Fuxin City.Therefore,more attention should be paid on the synergistic effect of building index and soil index of dryness component on ecological environment.
