Change of Land Use in Shendong Mining Area Based on Remote Sensing

Abstract

In order to understand the impact of mining activities on the local environment, taking Shendong mining area as the research area, the three phases of Landsat remote sensing images in 2000, 2010 and 2020 were classified and processed by using the supervised classification method, and the land use data of the three phases were obtained.Through the dynamic degree of land use and the transition matrix of land use, the changes of various land use types in Shendong mining area were studied.The results show that :grassland is the main land use type in Shendong mining area, accounting for more than 80% of the average during the study period.Construction land increased most significantly, with a growth rate of 53.37%.The grassland in the Shendong mining area is mainly transferred out, and a total of 196.74km² has been transferred out in the past 20 years, mainly to cultivated land and construction land.More grassland is occupied in urbanization development and mining activities.
