| 摘 要： | 以内蒙古四于王旗南部为例，研究了半干旱区农牧交错带风水交互侵蚀的特点．结果表明，该地区低山丘陵与宽谷相间分布，坡地上有大量疏松的沉积物；夏季降水以暴雨为主，春秋季多大风，形成风水复合侵蚀发育．每年夏秋季节的水蚀为风蚀提供了大量的沙物质，第2年春季的大风将沙物质进一步吹扬扩散，为水蚀的搬运提供了物质基础，如此反复．使水系的上游形成沟谷，中下游沙化迅速．

| Abstract: | Taking the south of Siziwang county as example, the characters of wind-water erosion of agro pasture zigzag zone in semi-arid region were studied. The results indicate that alternate there are ; In lternate erosions develops very much. in every summer and autumn,the water erosion provides much sand for the wind erosion. In the next spring, the strong wind blows and diffuses the sand everywhere, which provides with material elements for the water to carry. Repeating so and on,the gouge develops quickly in the upriver and sand spreads fast in the middle-downriver. |
