Analysis of Land Use Dynamic in Genhe City Based on GIS and RS

Abstract:

The paper chooses Genhe, Inner Mongolia as the research area. Based on ArcGIS 9.2 and ENVI 4.8 software, the TM images of 2000、2004 and 2010, the decision tree classification was applied to interpret the images, and the land use data of 2000、2004 and 2010 were obtained. The land use transformation matrix and land use dynamic degree were analyzed further. Results are shown as follows. (1) Decision tree classification can be used in the study area and classification accuracy is high. (2) Land use change underwent a process of obvious change from 2000 to 2010. The areas of forest and residential land underwent substantial increase, while the areas of sparse forest and grassland got a huge decrease.
