摘要
由于研究的视角及方法、手段的不同 ,水土流失研究中的植被因子指标表现出十分丰富的内容。本文集中分析了现有的各种植被覆盖指标 ,对其进行了大致的分类和比较 ,界定其内涵 ,以便为水土流失研究中对植被因素的理解提供一个较系统的视窗 ,避免指标的误用和错用。
There are many vegetation indexs in soil and water loss studies because of different study aims and practice ways. In this paper, all the existing vegetation indexs are analyzed to make a classification and comparison roughly; and their definitions are identified respectively. This would offer a good understanding and browse on vegetation factor in soil and water loss.
