| 摘 要： | 以1979年的MSS和2002年的ETM遥感影像为依据,运用遥感和GIS技术,开展了吉林省磐石市土壤侵蚀动态监测研究.利用亚像元分解法提取植被覆盖信息,结合土地利用和坡度信息进行了区域土壤侵蚀强度的动态监测研究.监测结果表明,磐石市1979-2002年土壤侵蚀状况呈现加重趋势,土壤侵蚀集中分布区不断扩展,侵蚀面积增大.该监测方法省时省力,极大地提高了土壤侵蚀动态监测的速度和效率,为大范围的土壤侵蚀动态监测研究提供了有效途径.

| Abstract: | Based on the MSS images in 1979 and ETM data in 2002,soil erosion change in Panshi City isstudied with the aid of RS and GIS. The sub-pixel models are used to estimate vegetation coverage and then landuse and slope information is combined to study regional soil erosion change. Results show that from 1979 to 2002, soil erosion became more serious and the main soil erosion region was gradually expanded and its ar-ea was increased. This method is highly efficient and can improve the speed and efficiency of regional soil ero-sion monitoring. It is an effective way to study regional soil erosion. |
