干旱区荒漠植被的特点及恢复问题的研究--以塔里木河流域胡杨林生态系统为例

干旱区除存在唯一的真正森林-胡杨(Populuseuphratica)林外,植被普遍极其稀疏,以降水稀少,蒸发显著为特点的干旱区,荒漠植被的存在对于生态环境的保护和良性发展起到极大的作用,干旱区的荒漠植被表现出特有的生理特征,本文研究塔里木河流域胡杨林的特征及对生态环境的适应规律,进一步提出了扩展荒漠植被的可能性及其措施。

Characters of Desert Vegetation in Arid and Research of Its Recovery--Take Tarim River Populus Euphratica Ecosystem for Example

In arid area, Populus euphratica is the only genuine forest ,vegetation is sparse at large ,since the water is rarely seen while evaporating significant as the dry area of the characteristics,existence of desert plants count for much to the conservation of ecosystem ,desert plants show specific characteristic ,In this article we study the feature of Populus euphratica in Tarim River and its regulation adapt to environment. Further come up with the possibility and measures to extend desert plants.
