The dynamic response of groundwater level is examined in traverse and lengthways directions. Take the Yinsu section for an example, we have simulated groundwater levels before and after water-conveyance every time and calculated the incidence of groundwater on the both sides of the river. It is noted that the effect keeps growing with the water-delivery times increasing, from 570 m after the first times to 3,334 m after the eighth times. In addition, this paper involves the temporal response of the natural vegetation to water conveyance, vegetation coverage, planted-species number, dominant position and species diversity from 2002 to 2006. The findings indicate that the positive influence of ecological water conveyance project (EWCP) on the ecosystem in the Lower Tarim River is a long-term process. In this paper, we try to calculate water required for recovery of damaged ecosystem by using data available. This project is likely the base of research on water demand and the reference of measures for research on ecological water conveyance effect.
研究了地下水位在横向和纵向的动态响应。以音苏断面为例，每次模拟了输水前后的地下水位，并计算了河道两侧地下水的影响范围。结果表明，随着输水次数的增加，影响范围不断扩大，从第一次输水后的570米增加到第八次输水后的3340米。此外，本文还涉及了2002年至2006年天然植被对输水的时间响应、植被覆盖度、种植物种数量、优势地位和物种多样性。研究结果表明，生态输水工程对塔里木河下游生态系统的积极影响是一个长期过程。本文尝试利用现有数据计算受损生态系统恢复所需的水量。该项目可能是需水量研究的基础，也是生态输水效果研究措施的参考。
