【摘要】 文章推荐了确定侵蚀、输移量的方法，指出坡耕地侵蚀过程中的＂填洼＂作用是引起输移比变化的原因，并分析了其变化规律。通过不同坡长的输移变化试验，发现单宽最小径流率ｑｍｉｎ和最大含沙量ρｍａｘ可判别其侵蚀输移变化，并划分出＂侵蚀─输移区＂、＂侵蚀─堆积─输移区＂和＂侵蚀─输移挠动区＂。对小集水区回归出输移比与坡长、面积的幂函数关系式。更多还原

【Abstract】 A method for determining the quantity of erosion and moving was discussed in the paper. Duriny erosion the main cause of the variation of moving ratio was the "filling of low-lying lands" in the sloping fields. Contral experiments were conducted on moving of different lengths of slope. It was found that the maximum of runoff ratio Per unit width and the maximum of sand carrying Per unit width sand could be used to discriminate the variation of erosion and moving.Areas of "erosion-moving" erosion-heaping - moving" and " erosion - moving interference"were divided. An exponent function equation for small water sheds was regressed according to the data of moving ratio, length of slope and size of slope.更多还原
