摘要
通过试验研究得出了黄土区土壤抗蚀性强弱的最佳指标——大于0.25mm风干土水稳性团粒含量的预测方程y=0.42+14.6x,在此基础上将土壤抗蚀性强弱定量地分为极弱、弱、中、强、极强五个等级,据此对黄土区土壤抗蚀性强弱进行了分类评价。
This paper describles a equation(y=0.42+14.6x)for predicting more than 0.25mm water-stable aggregate content, and the optimum index for soil anti-erodibility in air-dried soil. Based on this equation, the soil anti-erodibility is divided into five grades, and the classification and evaluation of soil anti-erodibility in Loess Region was made.
