Abstract:Comprehensive use of multi-source remote sensing data, the method of combining object-oriented image analysis and visual interpretation was used to interpret the land use or cover of Huainan mining area in 2007, 2010, 2013, 2016 and 2019. Through the calculation of statistics, dynamic degree, diversity index, utilization degree index and transfer matrix for each land use or cover type area and its proportion, the spatial and temporal change characteristics of land use or cover in Huainan mining area between 2007 and 2019 were analyzed. The results illustrated that: (1) The area and proportion of cultivated land in Huainan mining area has been declining continuously, a large number of cultivated land were destroyed, resulting in soil erosion, followed by urban and industrial land, and occupied by solid waste. (2) The order of dynamic degree of all land use or cover types was waterlogging subsidence area > lake reservoir > solid waste > industrial and mining land > forest land > bare land > urban land > road > cultivated land > rural residential land, indicating that coal mining activities have a great impact on land use in mining areas. (3) All mine land use or cover types were disturbed by human activities, and the land use diversity index and land use degree index increased.
