资源简介:
As part of the evaluation process, the K-factor is used for the first estimation of the erodability depending on the soil type. The K-factor contains soil properties such as permeability, infiltration, grain size, humus content and aggregate stability. The estimation by means of the K-factor provides rough statements regarding the erodability of the soil. In carrying out the assessment, the soil type of the uppermost soil horizon shall be taken into account. The Eb_Was_stage describes the erosion of the soil by water. Floor areas with strong slope inclinations (=18 %) receive a step surcharge.

作为评估流程的组成部分,K因子(K-factor)被用于基于土壤类型对土壤可蚀性开展初步估算。K因子涵盖渗透性、入渗能力、颗粒粒径、腐殖质含量与团聚体稳定性等土壤属性。借助K因子开展的估算可对土壤可蚀性作出粗略判断。开展该评估时,需将最上层土壤发生层(soil horizon)的土壤类型纳入考量范畴。Eb_Was_stage用于表征土壤的水蚀情况。坡度≥18%的地表区域将被施加阶梯式附加分值。
