- Abstract:
- On basis of field investigation and experimental research, impact of factors of climate of precipitation, runoff, temperature and wind etc and surface component material on soil erosion and sediment yield in the Liudaogou watershed and neighouring watersheds is analysed. It is considered that the key reason that soil erosion and sediment yield is severe intensity is big rainfall intensity, gale, few vegetation cover, loose component material of surface and bad physi-chemical properties. Soil erosion has characters of different types, and temporal and spacial distribution is not uniform. Coarse material of surface and big sediment yield is main source area of coarse sand. With the results, key control measures is that while soil erosion characteristics is mastered,pretecting wind sand directs into gully and river, sloping farmland is remaked, gully head andgully-wall slides, is prevented vegetation cover is increased, comprehensive agricultuer is developed.
