摘要: 通过对小金沃日河干旱河谷流域内维管植物的调查研究,得出区内维管植物具有如下区系特征:常见维管植物共计84科,181属,262种。种子植物占绝对优势。采用《四川植被》分类系统,将植被类型共分为4个植被型、4个群系纲、11个群系。植物种类较少,区系成分较为简单,该区种子植物区系具明显温带性质,植被类型较为简单,体现了较为明显的干旱河谷特点。

Abstract: Based on the research and analysis of vascular plants in Worihe drought valley in Xiaojin county,its floristic characteristics are as follows:there are 262 species in vascular plants,which belong to 163 genera and 73 families,thereinto seed plants are dominant.To introduce the system of "The vegetation in Sichuan",we can divide it into 4 vegetation forms,4 formation classes and 11 formations.It is not rich in floristics and simple in flora components.The seed plant flora is characteristic of temperate zone and simple vegetation embodies obvious features of drought valley.

Key words: Worihe drought valley, plant-diversity, study
