| 摘 要： | 塔里木河下游大西海子水库以下河道,自2000年5月至2004年10月,共进行了六次间歇性的生态输水。本文通过对胡杨样枝生长量的分析,表明输水对胡杨林的恢复具有显著的作用;同时依据历史期间的生态水量与胡杨林的对应关系,预测了在现状输水条件下大西海子水库以下可以恢复的胡杨林面积。

| Abstract: | The Tarim River is the longest inland river in China.It is located at the north of the Tarim Basin.However,the river flow in lower reaches had been cut to 357km since 1972.Along with ecological water transportation from the May 2000 to the Oct.2004 again,water transportations had achieved 6 times.Based on the growth increment data of Populus euphratica branch the effection of water transportation was discussed.As a whole,the water transportation had the significant role to the restoration of Populus euphratica.Then the relationship between volume of water transportation and the area of Populus euphratica in historical times was analyzed.In the end,the restorable area of Populus euphratica below the Daxaihai Reservoir was forecasted on the condition of intermittent water transportation. |
