集流梯田工程水土保持效益试验浅析——以黄前流域为例

Analysis on Soil and Water Conservation Benefit Experiment of Runoff Collecting Terrace Project——Take Huangqian Basin as an Example

集流梯田工程是水平梯田和自然坡地沿山坡相间布置的一种水土保持工程措施,较水平梯田更能提高土壤含水率,改善土壤理化性状,针对这一特点,在黄前流域进行集流梯田与水平梯田、坡耕地对比试验,研究与分析结果表明集流梯田具有显著的保持水土和提高作物产量的效果。本试验研究为有效治理水土流失和增加农民收入提供科学依据。

The runoff collecting terrace project is a kind of soil and water conservation measure, which is the alternate arrangement of level terrace and natural land on hillside. Compared with level terrace,it can improve soil moisture and soil physical and chemical properties. In view of this characteristic, a comparison experiment about runoff collecting terrace, level terrace and sloping farmland was carried out in Huangqian watershed. The result indicates that the runoff collecting terrace has remarkable effect of conserving soil and water and raising crop yield. This research provides scientific basis for controlling soil and water loss and raising peasant＇s income.
