Abstract: Based on GIS, the information on land use and soil erosion was interpreted from TM Remote Sensed Images. And by overlapping the respective map layers, the analysis was made on the relation between land use and soil erosion in the middle of Jilin Province. Results show the decreasing trend of soil erosion in the middle area of Jilin Province, mainly result from the decrease in erosion area of cultivated land which takes a large proportion in the middle of Jilin. But for other types of land use, the results show the increasing trend in soil erosion is in accordance with the increased intensity of land use. The transformation form water erosion to wind erosion indicates that the trend of climate change towards arid. The unreasonable land utilizeation causes the land in middle of Jilin Province to degradate further, which forms the vicious circle. So, it is imperative to out the optical utilization and reasonable development of water and land resources.

Key words: the middle of Jilin Province, land use, soil erosion, remote sense, GIS
