Paper Abstract

In this paper, by use of multitemporal satellite remote sensing, the dynamic change of land use about Xuzhou coal mining area in the east of China was monitored and analyzed. Firstly, with the use of TM images of Xuzhou in 1987, 1994 and 2000, the change maps of land use structure of their relevant periods of its West coal mining area were compiled. Secondly, the conversion matrix of land use structure about the different temporal classified TM images was interpreted. Finally, the status of the dynamic change of land use was analyzed comprehensively. The results indicate: (1) The area of subsided land due to coal mining was increasing, its extent was all bigger in 1987-1994 and 1994-2000, the increase rate of subsided land change every year was 6.33%, and which was the biggest rate of all land use change. (2) The cultivated land was the main land subsided due to coal mining, but the main use direction after subsidence land reclaimed was not cultivated land, and the cultivated land subsided due to coal mining was far exceed to that reclaimed. (3) Although the rapid speed of subsided land reclamation, and the reclamation rate all over 50% in 1987-1994 and 1994-2000, yet the speed of land subsided was also quick, the speed of land reclamation did not catch up with that of land subsidence. Therefore, it is necessary to accelerate the land reclamation, and adopt the effective measures to raise the ratio of cultivated land reclaimed from subsided land.
