土壤风蚀机理的研究

Research on Soil Wind-erosion Mechanism

阐述了土壤风蚀研究的历程及产生风蚀的根源是来自于农田和退化草地,论述了风蚀产生的原因、过程及影响风蚀的主要因子。由风蚀的研究历程可知:风蚀研究经历了定性描述、动力学试验分析及定量模型研究3个阶段。目前,风蚀科学的研究体系已初步形成,研究内容包括风蚀动力学、风蚀因子、风蚀模型、风蚀防治、风蚀环境效应、风蚀评价及研究方法论等。

This paper states the research course of soil wind-erosion and the main root of creating wind-erosion which generates from farmland and deteriorated grassland. This paper also discusses its generated reason and process, and its main influential factors. According to its research course, its research has experienced three periods, such as qualitative description, kinetic experimental analysis, and. quantitative model research. At present, it has been initially formed wind-erosion scientific research system. Its research contents include wind-erosion kinetics, wind-erosion factors, Wind-erosion model, wind-erosion prevention and cure, wind-erosion environmental effect, wind-erosion valuation, and its research methodology.
