摘要

采取路线考察和典型样地调查方法对内蒙古自治区杭锦旗穿沙公路段周边区域的植被群落进行了研究，分析了不同植被群落特征和物种多样性。结果表明，该区域共有16种植被群落，植物37种，分别隶属于14科30属。主要由沙地植物、盐碱化植物和低湿地植物组成。草灌类群落占优势地位，黑沙蒿等群落有较高优势度，但是在演替中处于退化趋势。沙柳、沙棘、柽柳等灌木群落虽然频度较低，但是优势度较高，说明在演替中处于进化趋势。

Abstract

Typical communities and species diversity on the different types of vegetation surrounding the region along the desert-crossing highway in Hangjin County of Inner Mongolia were analyzed by using the method of road inspection and typical investigation.Results showed that there were 16 communities and 37 kinds of plants in the region

which belongs to 14 families and 30 genera

respectively.They mainly included sand plants

salinization plants

and low-wetland plants.Shrub)grass communities were dominant and had a tendency of evolutionin succession

such asSalix psammophila

Hippophaer hamnoides

andTamarix chinensis.
