利用新型遥感生态指数的南宁市环境质量动态变化分析
Analysis of Dynamic Change of Environmental Quality in Nanning City Using New Remote Sensing Ecological Index
摘要
Abstract
With the rapid development of remote sensing technology,the use of Remote Sensing Ecological Index(RSEI)to monitor regional ecological environment quality has made some progress,but the impact of air quality on local ecological environment is rarely considered in the application of RSEI in different regions.In view of this limitation,Nanning city is taken as an example.Based on RSEI,the Difference Haze Index(DHI),which can accurately monitor urban air quality with high resolution,is added to build a new Remote Sensing Ecological Index(RSEInew).Then,the average correlation between RSEI and RSEInew and PC1 are compared and analyzed.It is verified that the constructed RSElnew model is more representative of regional ecological environment.Finally,RSEInew model is used to analyze the dynamic change of ecological environment quality in Nanning city.The results show that from 2013 to 2021,the ecological environment quality of Nanning city was optimized,the RSEInew was increased by 15％,and the overall ecological environment level was above medium(0.4～0.6).关键词
