【摘要】 采用野外定点观测法,主要研究植被各个特征对风力作用及土壤风蚀的影响。实验结果表明:植被对风速轮廓线的影响取决于植物总体的生态性和其本身的结构形态。植被盖度和高度均对风速轮廓线有明显影响,植被分布形式对其影响相对较小。在相同地风力条件下,植被的盖度是影响土壤风蚀的关键因子。植被高度和分布形式对土壤风蚀影响相对较小。更多还原

【Abstract】 Through field investigation,the influences of vegetation characteristics on wind profile and soil erosion were main studied.The result indicated that the effects of vegetation on wind profile lie in the ecological characteristic,both vegetation coverage and height have an obvious effect on wind profile,the influence of distribution type is little.If the wind condition is same or similar,the vegetation coverage is the key factor to the influence of the soil erosion;the effect of vegetation height and distribution type is relatively small.更多还原
