摘要

地方经济的快速发展与“西部大开发”实施中的开发建设项目的水土保持日益重要。紫色丘陵区开发项目的工程侵蚀严重

松散堆积物侵蚀模数为13895~52400t/(km2.a)

远高于相应对照草坡的侵蚀强度

其侵蚀产沙量与堆积物的形态与位置、坡度与坡长及植被覆盖度有关

其侵蚀也具有明显的时间特点。松散堆积物侵蚀的控制应选用土生藤本和草本植物。

Abstract

Soil and water conservation in construction programs becomes more and more important in local economic development and "China western development". Soil erosion from construction in the hilly area of purple soil is very serious with erosion modulus from 13 895 to 52 400 t/(km~2a) for loose construction deposits

which is much higher than that in contrast grassland. Soil erosion of loose construction deposit has special time dependant effects. Native-born liana and herbaceousplant should be chosen for soil and water conservation in loose construction deposit land.
