| 摘 要： | 土壤可蚀性是土壤侵蚀预报和土地利用规划的重要参数,国外已有物理意义明确、可操作性强、应用方便的土壤可蚀性定义和指标。国外的指标在我国不适用,而我国又没有这样的指标。在系统全面查阅和分析６０多年来已有研究成果的基础上,根据我国具体情况,提出我国土壤可蚀性指标的定义和测定方法,即在１５°坡度、２０ｍ坡长、清耕休闲地上,单位降雨侵蚀力所引起的土壤流失量。这一标准的确定对规范土壤可蚀性实验研究,促进我国土壤侵蚀预报模型的建立有重要意义

| Abstract: | Soil erodibility serves as a major parameter for soil erosion prediction and land use planning.Olson and Wischmeier gave it a very clear definition which has been used in many soil erosion models.However,it is not suitable for China.Based on the review of the 70 years research achievements on soil erodibility,and in light with China's actual conditions on land use as well as the available erosion data,the definition on soil erodibility index and its measurement in China was developed The soil erodibility for China might be defined as the average soil loss per unit of the erosion index from the clear tilled fallow on a plot 20 meters long on a slope of 15° This defi nition may help us for field measurement and Chinese soil erosion prediction model deve lopment. |
