| 摘 要： | 为了了解呼伦贝尔沙地植被的沙漠化演变规律及其机制,于2009年在呼伦贝尔沙地陈巴尔虎旗设置样地,调查不同类型沙地植被差异和变化特征,分析植被变化与土壤理化特性的关系,得到如下结果：①随着沙漠化的发展,草地的植被盖度、高度、地上地下生物量和凋落物量急剧下降,物种丰富度、多样性指数、均匀度指数和植物密度呈波动式下降;②沙漠...

| Abstract: | A field investigation on vegetation difference and change properties among different kinds of sand lands was conducted in the Qingbarhu Banner,Hulunbeir Sandy Land of Inner Mongolia in 2009 to understand desertification process and its mechanism of steppe vegetation.The results are as follows:(1) With development of desertification,the vegetation coverage,height,aboveground and underground biomass and litter yield of the steppe were sharply decreased,and the species richness,Shannon-Wiener index,Pielou even... |
