Measures Study And Benefit Analysis on Comprehensive Management in Small Watershed in Seriously eroded Purple Sand-earth Rock Region Case study in tielugou watershed of Fengdu County of Chongqing

Tielugou small watershed, which is the implementary small watershed of the "948" project of Ministry of Water Resources, gives prominence to the project of terracing on slope which places stress on basic farmland building and the developmental comprehensive control which is characteristic of ecological landscape of soil and water conservation in the comprehensive control of which. Through the comprehensive control, Tielugou small watershed has achieved the industrialization of measures of soil and water conservation and the obvious society benefits, meanwhile, the nicer ecological benefits. This paper researches the technology of the comprehensive control of soil erosion of Tielugou small watershed, and the ecology, economic and society benefits of which are analyzed. At the end, the paper summarizes the successful experience of the comprehensive control of Tielugou small watershed and the referenced significance to the small water control of sand-earth rock region.
