土壤风蚀影响因子与治理措施总结
首发时间:2009-08-28
摘要:土壤风蚀是制约世界各国农业可持续发展和环境质量的主要因素。本文通过对前人所作研究工作的总结,详细的介绍了土壤质地、风速、植被、作物残茬、土壤湿度、地形、人为因素等影响土壤风蚀的因子,并阐述了各相关因素与风蚀量之间的数量关系;同时总结了当前几种能够有效防治风蚀的措施及其各自的优缺点,旨在为今后开展相关土壤风蚀影响因子的实验研究和提出合理的治理措施提供一定的参考作用。

Summary of affecting factors and controlling measures of wind erosion of soil
Abstract:Wind erosion of soil is an important factor which limits the world agricultural sustainable development and environmental quality. Based on the existing work, we give the detailed introduction of factors, such as soil texture, wind velocity, vegetation, crop stubble mulch, soil moisture, terrain, artificial factors and so on. We also elaborate the quantitative relation between all related factors and wind erosion amount. At last, we summarize the exiting wind erosion controlling measures. The main purpose of this paper is to provide some references for experiment studys on wind erosion of soil and putting forward feasible controlling measures.
Keywords: wind erosion of soil affecting factors wind erosion amount controlling measures
