摘要: 应用修正风蚀模型(RWEQ)对四川省甘孜藏族自治州石渠县进行土壤风蚀模数估算, 分析土壤风蚀在石渠县的空间分布特征及各个因素对石渠县土壤风蚀作用的影响。结果表明, 石渠县北部抗土壤风蚀能力优于南部, 西南部受土壤风蚀影响最大;气象因子为土壤风蚀最主要的影响因子, 在6月汛期时土壤风蚀模数达到最大;植被指数的空间分布特征与土壤风蚀模数空间分布特征契合, 对其影响较深。

Abstract: The modified wind erosion model (RWEQ) was used to estimate the soil wind erosion modulus of Shiqu county, Ganzi prefecture, Sichuan province, and the spatial distribution characteristics of soil wind erosion and the effects of various factors on the soil wind erosion in Shiqu county were analyzed. The results showed that, the resistance to soil wind erosion in northern Shiqu county was better than that in southern, and the southwest was the most affected by soil wind erosion. Meteorological factors were the most important factors affecting soil wind erosion. The soil wind erosion modulus reached the maximum in the flood season in June. The spatial distribution of vegetation index was consistent with the spatial distribution characteristics of soil wind erosion modulus, and its influence was deep.

Key words: REWQ model, wind erosion, sand-fixing, Shiqu county
