胡杨、灰叶胡杨种群分布及地理关系的研究

Study on the distribution and geographic correlation of Populus euphratica Olivv & Populus Pruinosa Schrenk

研究了胡杨和灰叶胡杨种群的地理分布,阐述了胡杨和灰叶胡杨种群的地理位置变化,探究了它们的扩布机制和种群的进化关系.结果表明:胡杨和灰叶胡杨种群成集中分布型,分布走向与当地河流变化密切,种群具有从南向北的分布趋势.

Studied on the distribution pattern of Populus euphratica Oliv ＆amp; Populus Pruinosa Schrenk community,discussed on the location of the community changes of Populus euphratica Oliv ＆amp; Populus Pruinosa Schrenk,and deduced their spreading mechanism and the populus evolution.The results showed that their populus are mostly concentrated,which is closely to rivers,their trend is from south to north.
