基于RWEQ的20世纪90年代以来内蒙古锡林郭勒盟土壤风蚀研究

, 2014
土壤风蚀是中国北方地区重要的生态环境问题。锡林郭勒盟位于中国干旱、半干旱地区,是中国北方典型风蚀区,其特殊的地理位置又使得本区成为华北重要的生态屏障,为此锡林郭勒盟全区均划入了京津风沙源治理工程区。为了更好地阐明锡林郭勒盟的土壤风力侵蚀过程,指导区域的荒漠化防治,,基于气象、遥感数据,利用RWEQ模型定量分析了20世纪90年代以来锡林郭勒盟的土壤风蚀时空格局,揭示土壤风蚀的主要影响因素。研究表明:锡林郭勒盟多年平均土壤风蚀量为3.39亿t。土壤风蚀强度以微度和轻度为主,主要集中在植被较好,风蚀力较低 ...

A pan-European quantitative assessment of soil loss by wind

, 2016
Soil erosion by wind is a serious environmental problem often low perceived but resulting in severe soil degradation forms. On the long-term a considerable part of topsoil — rich in nutrient and organic matters — could be removed compromising the ...

Study on the relationship between topological characteristics of vegetation ecospatial network and sand fixation function in the Mongolian Plateau

Kuwait Journal of Science
The spatial structure of vegetation plays a pivotal role in determining the sand fixation function of ecosystems. However, the interaction between vegetation spatial structure at the regional scale and its sand fixation function remains insufficiently ...
