中文摘要1980年10月—1989年8月,用大比例尺制图和粒度分析法,观测研究蒋家沟内杨家坡和滑脚坡的坡麓堆积,两者堆积速度分别为5411,3046(立方米/年),侵蚀模量分别为22735,5382[立方米/(平方公里·年)]。两者平均为14058立方米/(平方公里·年)。蒋家沟流域内岩石剥落和切沟-冲沟泥石流的坡地面积13.3平方公里,泥沙流失量186978立方米/年。此值约为全流域泥沙流失量总值的1/10。
英文摘要From October, 1980 to August, 1989,the large-scale survering and grain-size analysis were applied to research on pediment deposit volumes of Jiangjia Basin. In Yangjiapo and Huajiapo,the deposit velocities are 5,411 and 3, 046(m3/a), the erosional modulus are 22,735 and 5,382 [m3/(km2·a)] respectively. The average value of them is 14,058m3/(km2·a).Here, there are tow types of pediment deposit- debris flow cone and talus, front made of debris flow body in rill and gully, after made of rock disintegrative body. With slope, degree is slowed down,with slope length and area of erosion slope increase,debris flow cone insteads of talus, with bank erosion is strengthen gradually, pediment deposit may apply to debris flow of main channel.The area of erosion slope is 13. 3km2 in Jiangjia Basin. Its pediment deposit velocity is 186,97 8m3/a, which is 1/10 of lost total volume of mud sand in Jiangjia Basin.
