| 摘 要： | 短命植物是早春多雨、夏季干热环境而形成的特殊植物类型,古尔班通古特沙漠南部是短命植物集中分布区,对保持沙漠稳定、防风固沙起到重要作用.目前对短命植物群落多样性、生态功能以及空间分布等研究较少.本研究采用分层抽样方法,调查分析了古尔班通古特沙漠南部35个样点3.86×104m2的短命植物多样性特征.共发现93个物种,分属...

| Abstract: | Ephemeral plants are a special type of plants living in an environment which is rainy in early spring and xerothermic in summer. In Gurbantunggut Desert,they are mainly distributed in the southern part,playing an important role in the maintenance of desert ecosystem stability and in sand-fixation. However,few studies have been done on their community diversity,ecological function,and spatial distribution. By adopting stratification sampling,this paper investigated the diversity feature of ephemeral plants a... |
