摘要
随着社会的不断发展,人们对自然生态环境质量越来越重视。本文主要利用遥感技术手段,以哈尔滨市延寿县为研究区,选取2019年的Sentinel-2A影像和Landsat-8影像,利用绿度、湿度、干度、温度等生态因子指标构建遥感生态指数(RSEI)模型,对延寿县生态环境状况进行综合评价。研究结果表明:延寿县RSEI空间分布的总体特征表现为中间差、周围好的地域特征,其东北和东南部RSEI值较高,中部RSEI值较低。
With the continuous development of society,people pay more and more attention to the quality of natural ecological environment.In this paper,remote sensing technology is mainly used to select Sentinel-2A image and Landsat-8 image of 2019 in Yanshou County as the research area,and use ecological factors such as green degree,humidity,dryness and temperature to build a remote sensing ecological index(RSEI)model to comprehensively evaluate the ecological environment of Yanshou County price.The results show that the overall characteristics of the spatial distribution of RSEI in Yanshou County are poor in the middle and good in the surrounding areas,with higher values in the northeast and southeast,and lower values in the middle.
