- Abstract:
-
Comprehensive management of small watershed is a kind of relatively mature technology which was extensively applied to regional soil erosion governance. In order to investigate its effect on the change of soil erosion intensity,based on eCognition, ArcGIS and two period remote sensing images of pre-and post-governance, the change of soil loss in the north of Jianshanhe valley was studied. The results indicated that soil loss showed a strong to weak trend between 2002 to 2006 in the north of Jianshanhe valley, before implementing comprehensive management of small watershed, the erosion intensity over serious erosion occupied 46.89% of the total land area, after implementing, the proportion decreased to 31.03%, moreover, the area of erosion intensity over middle intensity erosion has decreased with different degree, however, micro-degree erosion area significantly increased. So, comprehensive management of small watershed has achieved the significant effect.
