Second, main achievements in the freeze-thaw research are introduced and the changes of the property of soil and the soil erodibility affected by freeze-thaw are analyzed .
介绍并简要分析冻融作用对土壤性质的改变及对土壤可蚀性影响的主要研究成果;
Classical statistical analyses show significant spatial variability of soil erodibility K values at a scale of small watershed, the variance coefficient of which is 39.94%.
经典统计学方法分析表明,在小流域尺度下土壤可蚀性K值存在很强的空间变异性,其变异系数达39.94%。
The research on soil erodibility is a crucial tache in understanding the mechanism of soil erosion.
对土壤可蚀性的研究是认识土壤侵蚀机理的一个重要环节。
The percentage table of rainfall erosivity for a half month period was used to calculate soil erodibility and vegetation coverage factors.
半月降雨侵蚀力占年侵蚀力的累积频率表,为估算土壤侵蚀方程中土壤可蚀性因子和植被覆盖—管理因子提供了基础。
The influences made soil aggregation decreased, clay content increased and finally soil erodibility enhanced.
其结果是团聚作用降低而黏粒含量增加,最终导致土壤的可蚀性加大。
