| 摘 要： | 以塔里木河下游10次生态输水的效果为背景,根据近5a在塔里木河下游阿拉干断面的大量野外调查数据,分析了胡杨冠幅对应急生态输水的响应.结果显示:随着输水次数的增加,胡杨冠幅呈梯度变化的趋势,输水对增加胡杨叶量和活枝有一定的促进作用,不同冠幅级的胡杨主要分布在距河道200 m的范围,且其分布都与离河道距离呈显著负相关关系,...

| Abstract: | A study was performed to analyze the positive response of crown diameter(CD) of Populus euphratica to ecological water transfer based on a large number of data obtained from field investigation in the past five years along the Argan section in the lower reaches of Tarim River.Results show that the CD of P.euphratica has a tendency of gradient change with increasing number of water transfer,and the man-made ecological water transfer has played a significant role in increasing foliage mass and live branches of P.euphratica.P.euphratica with different levels of CD are mainly distributed within a distance of 200m from the riverbank,and there is an obvious negative correlation between the distribution of P.euphratica and the distance from the riverbank.The CD of P.euphratuica in different distances from the riverbank has a various response to the water transfer.The general trend is that the CD of P.euphratica does not change obviously with the increasing distance from the riverbank. |
