塔里木河下游应急输水植被响应效果调查与初步分析

Investigation on the Vegetation Recovery Responding to the Urgent Water Transportation to the Lower Reaches of Tarim River

本文根据塔里木河下游四次应急输水后不同断面、离河岸不同距离植被恢复的现地调查数据 ,结合输水河道两侧相应地下水位空间变化规律 ,分析塔河下游输水河道两侧不同地下水埋深梯度地表相应植物的生态恢复指征 ,以此为输水的生态有效范围和输水周期提供科学依据 ,为科学的指导和调度塔河下游生态输水提供依据。

According to the data of spot survey to different cross-sections and the recovery of vegetation with different distances from the river bank after the four times' urgent water transporting to the lower reach of Talimu River ,and linked with the responding space regular variation of water-table by both sides of the watercourse, this article analyses the indicative characters of ecological recovery of vegetatuion responding to different levels of ground water by both side of the transporting watercourse ,which is the scientific basis of the ecological effective range and periods of the transporting ,and basis of scientifically guiding and dispatching the ecological water transportation to the lower reach of Talimu River.
