Assessing Ecological Quality Based on Remote Sensing Images in Wugong Mountain

Earth and Space Science, Volume 9, Issue 3, March 2022., 2022
Abstract This study takes multitemporal Landsat images as data source to explore the changes of Fractional Vegetation Cover (FVC) and ecological quality (EQ) of the Wugong Mountain (WGM). The regression model obtained from MODIS NDVI data was used to correct the temporal difference of Landsat normalized difference vegetation index (NDVI) data in 2019 ...

LONG-TERM ECOLOGICAL ENVIRONMENT CHANGE MONITORING IN SCALE OF CITY ALONG CHINA-EUROPE RAILWAY EXPRESS WITH A REMOTE SENSING-BASED ECOLOGICAL INDEX (RSEI): A CASE STUDY IN WARSAW, POLAND

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Abstract. The China-Europe Railway Express (CER-Express) has developed rapidly since its opening, but little attention has been paid to the long-term ecological environment changes along its route, especially in scale of city. This paper studies the long-term changes of cities along the route before and after the opening of CER-Express.
