Abstract
通过在重庆万州区对冬小麦、油菜、春玉米和裸地4种试验小区进行5种雨强的人工模拟降雨试验,研究不同农作物对降雨侵蚀的影响。结果表明:不同作物小区的产流产沙速率存在显著差异,产流产沙速率均与降雨历时呈对数正相关关系;相同雨强下,4个模拟试验小区的产流产沙速率、总径流量、侵蚀产沙量大小均为裸地>冬小麦>油菜>春玉米。作物的蓄水保土功能是地上部分和地下部分(根系)共同作用的结果,3种作物水土保持功能由高到低依次为春玉米最佳,油菜次之,小麦最差。
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.
