In order to explore through comprehensive improvement, improve the ecological environment, summarize the experience of Qingshi mountain area to get rid of poverty and prosperity, we conducted a pilot study on the development and utilization of small watershed in Nan Yan village in 1985, and achieved initial results. For the following introduction, for reference. First, the pilot area Survey The experimental area is located in Wulan Town, Qingzhou City, South Yan Village, where three sides of the mountain side of the ditch, is a hydro-rock mountain. Is a natural gourd-shaped small watershed, an area of 1.6 square kilometers, of which 2,100 acres of barren hills, 495 acres of farmland. Whole village
