关于土壤可蚀性指标的讨论

A Review on the Indexes of Soil Erodibility

该文对主要土壤可蚀性指标进行了评述，指出土壤的可蚀性是一个相对概念，同一土壤在不同侵蚀动力条件下，其抗侵蚀能力是不同的。每一土壤均具有抗蚀性和抗冲性，在土壤侵蚀过程中，何者居主导地位，主要取决于侵蚀动力的方式和强度。建议加强利用人工降雨等手段对不同土地利用和土壤类型的土壤可蚀性进行系统研究，并使其标准化、定量化，为土壤侵蚀量预测和坡地治理开发服务。

The main indexes of soil erodibility have beeii discussed.Soil erodibility is a relativeconcept,it is sugguested that the soil anti-erodibility and soil scourability should be separated inthe study of soil erodibilitv,Soil has different erodibilities under the various forms and intensitiesof erosive force,so the condition of erosive force should be considered for selecting the indexes ofsoil erodibility.
