土壤水蚀影响因子与土壤退化研究进展

A review of soil degradation and affecting factors of water erosion

系统地综述了水蚀影响因子及其作用特性,包括土壤可蚀性、植被因子与降雨侵蚀性,概括了由水蚀引起的土壤物理(土壤薄层化、粘化、持水力下降等)退化特征,以及土壤养分流失、地力衰退的明显性,也概述了防治侵蚀退化的有效措施。

This paper presented a detailed review upon the impacting factors and degradation characteristics of water erosionas well as countermeasures of preventing degradation caused by water erosion. The influencing factors included soil erodibilityvegetation coverage and rainfall features.Soil physical degradationincluding soil loss clay-enrichingand field capacity declining and etc.as well as soil nutrient loss and productivity decay were summarized.
