硬地面侵蚀产沙模拟试验研究

硬地面由于具有容重大、地表完全裸露、易受人为干扰等特性 ,因而其产沙特性有其自身的规律。在人工降雨实验模拟的基础上 ,对硬地面次降雨侵蚀产沙过程和影响硬地面侵蚀产沙的因素进行了初步探讨 ,为硬地面的侵蚀防治提供了科学依据

Because of hard ground surface characters of big bulk densities, bare surface and be disturbed easily,the hard ground surface has its laws about sediment yield. Based on artificial rainfall,the courses of sediment yield were studied, at the same time, analyze influence of rainfall intensity, gradient and bulk densities to sediment yield amount.
