| 摘 要： | 以毛乌素沙地巴图塔沙柳基地为研究区域，采用野外调查和统计分析相结合的方法，对沙障设置前后的植被动态变化、物种多样性进行研究，进而分析沙柳沙障对植被恢复的影响。研究结果表明:随着沙障设置年限的增加，群落的物种数增加；群落类型由沙障设置前的沙米+沙竹群落发展成沙柳人工植被群落，在演替过程中无物种消失，物种多样性与沙障设置年限基本呈正相关关系。证明流动沙丘上植被恢复过程中沙柳沙障起着重要促进作用。

| Abstract: | Vegetation dynamic change and species diversity in Batuta were studied with field investigation and statistical analysis. Analyze vegetation restoration under the influence of Salix sandy barrier deeply. The result shows species gradually increase. Agrioph yllum squrrosum and Psammochloa villosa community change Salix Cheilophila Schntid artifactitious vegetation community. No species was disappeared in succession. Between the species diversity and the time sandy barrier was positive correlation. So, sandy barrier is key to vegetation restoration. |
