| 摘 要： | 利用1989，1999年的TM和2007年SPOT5遥感影像，运用RS和GIS技术对四川省甘孜州道孚县甲斯孔林场土壤侵蚀状况进行了动态监测研究。结果表明，天然林保护工程实施前(1989-1999年)，研究区轻度侵蚀区和强度侵蚀区面积不断增加，说明土壤状况整体上处于恶化趋势；实施天然林保护工程后(1998-2007年)，强度侵蚀区面积下降，中度侵蚀区面积上升，表明水土保持状况趋于好转，土壤状况恶化趋势得到反转，但改善幅度不够明显。天然林保护工程在促进植被恢复和提高水土保持功能等方面有着积极的作用。

| Abstract: | Based on the TM images<1989 and 1999)and the SPOT 5 images(2007),the dynamics of soil erolion in the Jiasikong forest farm of Daofu County,Tibetan Autonomous Prefecture of Uarze,Sichuan Province,was monitored using remote sensing(RS) and geographical information system(UIS).Results show that the area of moderate erosion and severe erosion increased from 1989 to 1999,before the implementation of the natural forest protection project(NFPP).After the implementation of the NFPP,the area of severe erosion deceased as accompanied with the increase of moderate erosion area,indicating a better situation of soil and water loss control.The deteriorating tendency of soil erosion has been inversed,but the inversed degree is not significant.This suggests that the NFPP has an important effect on promoting the vegetation restoration and improving the functions of soil and water conservation. |
