Other Abstract
The rainfall experiments were made in Wanzhou region, Chongqing. The experiments included four experiment plots: winter wheat(Triticum aestivum Lin.),rape(Brassica campestris L.), spring maize (Zea mays L.) and bare land. Effects of different crops on the runoff and sediment were studied. The results showed : The rates of runoff and sediment of different simulation experiment plots had significant differences. The rates of runoff and sediment had a logarithmic positive correlation with the rainfall time. Under the same rainfall intensity, compared the rates of runoff and sediment, runoff volumes and erosion sediment yields of the four experimental plots showed bare land >winter wheat>rape >spring maize. The functions of soil and water conservation of fours crops were mainly controlled by aboveground parts and underground parts(roots). Compared the functions of soil and water conservation of three crops: Spring maize was the best, rape was the second,winter wheat was the worst.
