The Environment Background and Administration Way of Wind—water Erosion Crisscross Region and Shenmu Experimental Area on the Loess Plateau

Tang Keli Hou Qingchun Wang Binke Zhang Pingcang (Northwestern Institute of Soil and Water Conservation, Academia Sinica and Ministry of Water Resources, 1Yangling, Shaanxi, 712100)  
The most serious soil erosion in the loess plateau exists in the wind—water erosion crisscross region where the annual precipitaton is about 400mm. It is the typic fragile ecologic environment region showing that the climate change is very violent, the vegetation is very scattered and the soil erosion occurs in the whole year. In spring the wind erosion is very serious and in the summer and autumn the storm erosion is very frequent, wind erosion and water erosion occur alternatively and accelerate, which makes the erosion modulus above 10000t/km~2·a. The area connecting the Shanxi, Shaanxi, Inner Mongolia and including the Shenmu experimental area is the most serious erosion centre of this region and main source of the coarse sediments of the Yellow River. In view of the urgency of the controlling Yellow River and the coal field development the Shenmu experimental area establishment for envionmental administration experimentdemonstration research has the extensive practical directing significance. By the comprehensive analyzing the superiority and inferiority and taking the small watershed as the unit it is discussed that new way of industry—subsidiary and agriculture combination, simultaneous development, of ecological and economic benefit agriculture forestry and animal husbandry are going forward to the commercialized and marketed
