- Abstract:

Using methods of cluster analysis, correlation analysis, relationship and classification of soil and water conservation measures and soil erosion of sub-watersheds involved by ‘Changzhi five-phase project’ was studied in Sichuan Province. The objective of this research is to provide primal data for assessment of small watershed comprehensive management and effect of water and soil conservation measures on soil erosion. Region plan is to be worked out. The results showed that soil and water conservation measures could be divided into four categories, the area of the third types dominated by Grazing Ban and cultivation by conserving soil had 146 sub-watersheds and accounted for 68.9 percent of the total area. Soil erosion could also be divided into four categories, the area of the first and the fourth types dominated by insignificant erosion, slight erosion had 158 sub-watersheds and accounted for 74.6 percent of the total area. Relationship between soil and water conservation measures and soil erosion was that the area that dominated by Grazing Ban and cultivation by conserving soil were eroded insignificantly or slightly, Grazing Ban and cultivation by conserving soil had obvious effect on preventing soil erosion.
