摘要

[目的] 针对塔里木河下游现状间歇性河道输水中存在补给不均衡，无效蒸发过大，补水范围有限等问题，从空间和时间维度上提出生育期汊河输水、非生育期输水的方式，研究输水模式的改进对地下水位的影响，进一步完善轮渗灌溉生态修复体系，为塔里木河下游生态恢复提供理论依据。[方法] 以塔里木河下游英苏监测断面为例，以2012—2021年10次生态输水期间地下水埋深监测资料为依据，运用Modflow模型建立英苏断面地下水剖面二维流运动的数值模拟，并分析英苏断面10次间歇性生态输水的响应过程，并预测和分析了生育期汊河、非生育期以及非生育期汊河输水的地下水位演变及水量变化的过程。[结果] ①生育期汊河、非生育期、非生育期汊河方案下人工汊河两侧地下水位较现状输水分别抬升了2.5，0.7，3.2 m。②3种改进方案较现状输水研究区小于8 m的埋深面积分别增加了10.89%，19.33%，26.17%。③地下水存储量较现状输水分别增加了10.97%，11.88%，14.39%。[结论] 非生育期汊河输水结合了生育期汊河和非生育期输水两者的优势，提高了下泄水量的利用率，解决了现状主河道输水模式下河间地下水位难以恢复的问题，为河间地块生态系统的恢复并使其成为下游生物多样性的安全带创造了条件。

Abstract

[Objective] In view of problems such as unbalanced recharge

excessive ineffective evaporation

and limited water supply range in the current intermittent channel water transport exist in the lower reaches of the Tarim River

the spatial and temporal water transport modes during the growth and non-growth periods and the influence of improvements of water transport mode on the groundwater level were analyzed in order to further improve the ecological restoration system of rotary infiltration irrigation and to provide a theoretical basis for ecological restoration in the lower reaches of the Tarim River. [Methods] The study was conducted in Yingsu monitoring section of the lower reaches of the Tarim River. Groundwater depth was monitored during ten ecological water conveyances from 2012 to 2021. The Modflow model was used to numerically simulate two-dimensional flow movement of the groundwater profile in Yingsu section. The response data of ten intermittent ecological water deliveries in Yingsu section was fitted and analyzed. The process of groundwater level evolution and water quantity change during the growth period

the non-growth period

and in the artificial water channels in non-growth period were predicted and analyzed. [Results] ① Under the proposed schemes of water delivery during the growth period

non-growth period

and in the non-growth period with the artificial river channels

the groundwater levels on both sides of the artificial river channels were raised by 2.5

0.7

and 3.2 m

respectively

compared with the current water delivery system. ② The area of groundwater depth less than 8 m in the study area was increased by 10.89%

19.33%

and 26.17% under the three improvement schemes compared with the current water delivery system. ③ The groundwater storage capacity was increased by 10.97%

11.88%

and 14.39% compared with the current water delivery system. [Conclusion] The artificial water channels in the non-growth period combined the advantages of both artificial water channels in the growth period and the non-growth periods

improved the utilization rate of downstream water discharge

solved the problem of difficult recovery of groundwater level under the current water delivery mode in the main river channel

and created conditions for the recovery of the inter-river ecological system and the establishment of a safe zone for downstream biodiversity.
