Closed mine functional zoning planning based on remote sensing image data
In order to explore the functional zoning planning method of closed mines,Xinxie mining area was taken as the re-search object.Based on the multi-period satellite remote sensing image,the land use status of the study area was obtained.The hot spot spatial clustering method and PLUS prediction model were used to predict the hot spot area and land use spatial distribution in the study area in 2025.It is found that the expansion and change of water body in Xinxie mining area is sig-nificant.The hot spot area is water body type,the cultivated land is unchanged area,and the cold spot area is scattered patchy distribution of forest land and grassland type.Based on the prediction results,the survey results of land use status and the distribution characteristics of mine geological environment problems,the Xinxie mining area is divided into five function-al zoning areas,which are water body and forest land function improvement area in area Ⅰ,subsidence water area and agri-cultural land function improvement area in area Ⅱ,water body and cultivated land and wetland landscape land function im-provement area in area Ⅲ,water body and agricultural land function improvement area in area Ⅳ,water body and agricultural land function improvement area in area V.The governance improvement plan and land use suggestions for each functional partition are put forward.
