摘要
中国是世界上水土流失最严重的国家之一,水土流失是我国的头号环境问题.以典型岩溶区贵阳市为研究对象,用2010年ASTER影像为信息源,开展适合喀斯特山区水土流失遥感监测的技术方法研究.研究表明,利用遥感技术和地理信息系统获取岩溶区水土流失因子能实现区域水土流失快速监测,可有效地促进水土保持工作的顺利开展.贵阳市2010年水土流失面积为3 234.1km2,占总面积的40.3%,水土流失面积呈逐步下降的趋势,但水土保持形势依然十分严峻.
China is one of the most serious soil erosion countries in the world, water and soil loss is our country＇s environmental problems. Using typical karst area of guiyang as the re- search object, and using 2010 ASTER images, to find suitable methods of soil erosion monito- ring by remote sensing in Karst district. Research shows that. using remote sensing technology and geographic information system extract soil erosion factor can realize rapid monitoring of soil and water loss, can effectively promote the soil and water conservation work. Guiyang 2010 soil erosion area is 3 234. 1 km2, accounting for 40.3% of the total area, Guiyang＇s soil and water loss area had been gradually declining, but the situation remains very serious.
