摘要

The ecological environment construction is an important part in the Development of West China. The loess plateau, especially the loess hilly and gully region, is closely linked with the permanent control of the Yellow River because of its serious soil and water loss, so it occupies a peculiar position in the ecological environment construction of West China. People from government officials to scientific researchers are always concerned about finding a road that could conform to reality, have the function of demonstration and extension, and make the society-economy-ecology to be coordinately developed. The national key project from 1996 to 2000, the topic of which was sustainable development of conservational eco-agriculture in the loess hilly and gully region of North Shaanxi (Ansai), was carried out in Zhifanggou watershed with an area of 8.27 km~2 and gully density 8.06km/km~2, located in the middle part of the loess plateau, Ansai County, Yanan Municipality, Shaanxi Province. The watershed of Zhifanggou is in the juncture of semi-arid and semi-humid climates. Its annual precipitation was 504.3mm and annual mean temperature 8.8℃ in 1970—2000. Its population density was 64 persons per square kilometer in 1996—2000. It represents No.2 sub-section of the loess hilly and gully region, located in Yanan Municipality mainly. The non-rational land utilization, the sparse trees and grass, the serious loss of soil and water, the degenerated ecological system, the lower grain yield per unit area, and the poor living standards of the masses are major problems in No.2 subsection of the loess hilly and gully region.
