摘要

抗蚀性是与抗冲性既有联系，又有区别的一个衡量土壤抗侵蚀能力的重要指标。在黄土高原的两大侵蚀类型区--高塬沟壑区、丘陵沟壑区，分布着数百万公顷沙棘人工林，其抗侵蚀能力愈来愈受关注。要正确评价沙棘人工林的抗蚀功能，一个科学、有效、便利的评价体系是不可缺少的。在反映土壤抗蚀性的纷杂繁多的指标中，经过主成分分析，筛选出了符合不同精度要求的“最佳指标”、“最佳2指标”、“最佳3指标”等评价体系。

Abstract

Anti-erodibility is one important index to estimate soil anti-erosio n capacity which has relation and difference with anti-scouring ability.There are tho usands of hundreds hectare Hippophaer hamnoides forest in loess plateau region

and its anti-erosion capacity has been paid more and more attention.One scientific

effective and advantage evaluation system is essential to evaluate anti-erosion capacity of Hippophae rhamnoides forest.Using principal component analysis

different evaluation system—“Optimum 1 Index”

“Optimum 2 Indexes”

and“Optimum 3 Indexes”are chosen among many indexes.
