黄麻土工布控制红壤坡面侵蚀的研究

采用长期室外径流观测和人工模拟降雨的方法，在第四纪红色粘土母质发育的红壤上进行黄麻土工布保持水土的研究，结果表明：黄麻土工布具有很好的水土保持效果，能推迟初始产流时间，减少径流，防止沟蚀产生，与裸地相比，保水效益高达７５％，保土效益达９９％。黄麻土工布覆盖并结合营造植物，可更提高水土保持的持续效果。

Study on Slope Erosion Control with Jute Geotextile on the Red Soil

The jute geotextile was covered on the surface of Quaternary red soil in the test plots. By the aid of rainfall simulation, the soil loss amount and its process was measured. The result shows that jute geotextile can conserve soil and water efficiently on the slope land, which delays the start of runoff, increases infiltration, reduces the amount of runoff and avoids rill erosion. The plot of jute geotextile keeps 99% more soil and 75% more water than bare land. Combining with biological measures, jute geotextile can achieve sustained benefits.
