摘要
Abstract
Taking the Yanshui River Basin as the research object,based on the Landsat8 OLI remote sensing images in 2013,2017 and 2021,the NDVI(normalized difference vegetation index)and pixel dichotomy method were used to calculate and analyze the FVC(vegetation coverage)of the study area from 2013 to 2021.The results show that the average NDVI values of the Yanshui River Basin in 2013,2017 and 2021 were 0.3076,0.7517 and 0.8343,respectively,and the FVC was mainly high coverage,accounting for 54.62％,75.50％and 86.13％.The FVC in the upper,middle and lower reaches of the basin showed different trends.The upper and middle reaches were mainly high coverage and continued to increase,while the lower reaches were mainly medium,low and very low coverage,and the increase in very low coverage was the most significant.The change in vegetation coverage in the basin conforms to its development law.关键词
