| 摘 要： | 通过对湘中丘陵缓坡梯土的定位研究，对６个试验迳流小区和一个对比迳流小区的迳流系数、输沙率在未间种作物时进行探讨，揭示了７个迳流小区的保土保水能力，对林下间种的花生、油菜覆盖度与输沙率的关系进行了深入研究，找出了花生与油菜的覆盖度的动态变化对输送率的影响。并对时间模式与年迳流量、泥沙量的关系进行了探讨。

| Abstract: | After location investigating on the slow-up hill terrace at central Hunan, the runoff coefficient, sediment discharge from six experimental runoff plots and one control plot without companion crops was analyzed, which found out the capacity of soil conservation of those plots Also the correlation between the sediment discharge and cover intense of groundnuts and rape was studied, which found out the effects of dynamic variety of cover intense on the sediment discharge Meanwhile the companion cropping, annual runoff volume and amount of sediment were discussed in this paper |
