摘要
以哈尔滨市区为研究区,基于2013年、2017年及2021年3期Landsat-8遥感数据,选取干度、热度、湿度和绿度四个指标作为体现生态环境质量的指标,利用RSEI,并结合生态质量等级差值运算法,对哈尔滨市区"十二五"至"十四五"期间生态环境的时空变化情况进行分析评价.结果表明:2013—2021年哈尔滨市区生态环境质量在逐渐上升,西部和南部整体的生态环境质量相对较差,北部的RSEI指数相对其他地区较高.
Abstract
Taking Harbin urban area as the study area,based on the Landsat-8 remote sensing data in 2013,2017 and 2021,four in-dicators of dryness,heat,humidity and greenness were selected as the indicators reflecting the ecological environment quality,and the new remote sensing ecological index (RSEI) and the ecological quality grade difference algorithm were used to analyze and evaluate the temporal and spatial changes of the ecological environment of the urban area of Harbin from the 12th Five-Year Plan to the 14th Five-Year Plan. The results showed that from 2013 to 2021,the ecological environment quality of Harbin urban area was gradually improving,the overall ecological environment quality in the western and southern parts,while the RSEI index in the northern part of Harbin is higher than that in other areas.
