| 摘 要： | 以塔里木河下游为研究区,以区域内9个固定监测断面为基础,依据断面内各个地下水监测井,收集了输水前和第15次输水后的地下水位数据,结合土壤饱和差计算方法,分析了第15次输水后的地下水补给量,并联系植被生长所需的合理水位探讨了地下水到达合理水位所需的水量,以期评价生态输水的阶段性效果,为调整生态输水方案提供理论参考。结果表明:(1)生态输水前地下水埋深在6~13 m之间,第15次生态输水后,地下水最大升高幅度达到8.26 m;(2)第15次生态输水后,塔里木河下游地下水补给量约为20.44亿m3;(3)为使地下水达到植被生长所需适宜水位,塔里木河下游地下水的合理需求量约为24.08亿m3。

| Abstract: | The lower reaches of the Tarim River was selected as the study area. First, the data of groundwater level were collected before water transport and after the water transport was carried out 15 times, based on the locations of groundwater monitoring wells at nine sections. Then, the groundwater recharge amount after the 15th time of water transport was analyzed using the calculation method of saturation deficit of soil. Finally, the suitable demand amount of groundwater that enables the groundwater level to reach a water level suitable for plant growth was determined. This study aimed to evaluate the effects of ecological water transport at different stages and provide theoretical references for the adjustment of water transport. The results are as follows: (1)the depth to water table ranged from 6 m to 13 m before ecological water transport, and its maximum increment reached 8. 26 m after the 15th time of water transport; (2)the recharge amount of groundwater was about 20. 44 × 108 m3 in the lower reaches of the Tarim River after the 15th time of water transport; and(3)the suitable amount of groundwater in the lower reaches of the Tarim River should be about 24. 08 × 108 m3, in order to guarantee the suitable water level for plant growth. |
