中文摘要抗蚀性指标是表示土壤抗蚀性能的特征值。本文通过对黄土丘陵区五(省区)7个点不同类型土壤抗蚀性指标的测定,用典型相关法和主成分分析法,将这些指标分为水稳性团粒类、原因类和分散类等三类。最佳土壤抗蚀性指标以>0.25mm 水稳性团粒的含量为最好;其余指标,特别是分散类中的各指标不宜在本区推广使用。
英文摘要Soil anti-erosibility is an important part of soil erosion re- search.The samples of different soils and land uses were collected from seven countres in five provinces.based on determination of 18 indices of soil erodibility,Canonical Correlation Analysis and Principal Component Analysis the following results are obtained. 1)All of indices of soil anti-erosibility are classified three groups. The first is water stable aggregate content group.The second is reason group,in which concluded 4 indices.The remains of indicess belongs to the third group. 2)The best is the first group,in which the best indite is>0.25mm water stable aggregate content of air-dried soil samples,the remain groups,especially those which based on microaggregate content are not adapted to the region
