【摘要】 对中国北方农牧交错区风蚀变化最为明显的地区进行定点研究 ,并选取一个小流域作为研究对象 ,测量了农村交通用地的土壤风蚀状况 ,计算结果表明 :交通工具对土壤作用加速了土壤风蚀过程 ,扣除车轮挤压地面下降外 ,交通工具引起的土壤风蚀速率在 2 .9～ 3.8cm /a之间。由此可见 ,在减缓农牧交错区土壤风蚀方面 ,农村交通道路风蚀问题必须予以考虑。根据社会经济的发展 ,对交通道路进行固化可减缓这类用地的风蚀状况。更多还原

【Abstract】 Wind erosion is one of nature disaster in the world. With the development of society and population increasing, human being’s activity play an important role in this disaster process. The way of wind erosion rate is decided by regional land use. The patterns of land use are multiplicity. Traffic land use is one way of them. In this paper, wind erosion is studied in its obvious region in agriculture and animal husbandry intercrossed zone of north China. Small drainage basin is chosen as study object. Wind erosion condition of traffic land use is measured in countryside. The results show that vehicles act on roads and accelerate the soil erosion process and vehicle’s extrusion and drop to the road ground is subtracted and then vehicles caused wind erosion rates between 2.9～3.8 cm /a. Thus it can be seen, in the aspect of wind erosion in agriculture and animal husbandry intercrossed zone of north China, wind erosion of countryside road must be taken into account. According to the development of society and economy in this region, solidified country roads could reduce wind erosion of this kind land use.更多还原
