摘要

内蒙古砒砂岩地区是黄河重要的粗沙来源区

具有水蚀、风蚀及重力侵蚀交互的特点。利用 3个试验流域1983～ 1997年的天然观测资料

分析得到了砒砂岩侵蚀交互作用的时空分布规律 ;通过对砒砂岩的理化性质及侵蚀产沙特性的分析表明

砒砂岩的产流和产沙能力均高于当地的黄土和风沙土。建立了砒砂岩地区的水蚀模型

并对水力侵蚀过程进行了模拟

Abstract

The region of sediment rock in Inner Mongolia is the main source of the coarse sediment for the Yellow River

which has the character of the interaction of wind erosion

hydraulic erosion and gravity erosion.Using the natural observation data

we analyzed and got the rules of spatial and temporal distribution of the interaction of wind erosion

hydraulic erosion and gravity erosion. According to the study on the chemical and physical features and the rules of soil erosion and sediment yield for the sediment rock

we got the result: the capabilities of runoff yield and sediment yield are higher than the loess soil and aeolian sandy soil. We built up the hydraulic erosion model and simulated the erosion process of the study region.
