| 摘 要： | 土壤风蚀与风、土壤粒径组成和地表植被覆盖度有关,在农牧交错带缓坡丘陵区,风蚀是很严重的自然灾害。通过在有风的天气对丘陵不同坡向和坡位的风速和风蚀量以及土壤粒径进行测定和分析,得出丘陵不同部位受侵蚀大小是坡顶大于北坡、北坡大于南坡。该项研究为控制缓坡丘陵土壤风蚀提供了理论支持。

| Abstract: | Soil wind erosion is related with wind, composition of soil particles and degree of land surface vegetation. Wind erosion is a serious natural disaster in hilly land with gentle slopes in crisscross area of agriculture and pasture. The paper measures and analyzes wind velocity, quantity of wind erosion and soil particles of different slope directions and locations under the windy condition. The results are shown that the erosion at slope top is greater than that of north slope and north slope greater than that of south slope. The study has provided theoretical support for controlling soil wind erosion of hilly land with gentle slopes. |
