Reasonable scale of Taitema Lake based on the dynamic change of the groundwater level
Ecological water transportation is an important measure for the protection of the"green corridor"in the lower reaches of the Tarim River,and the maintenance of the Taitema Lake surface is the"touchstone"for comprehensive management of the Tarim River.Analyze the changes in groundwater level of Taitema Lake at the end of the Tarim River under ecological water transport,combined with the dynamic process of water surface area of Taitema Lake during the same period,analyze the changes in lake surface area under ecological water transport,and explore the suitable scale of Taitema Lake in the future.The results show that:compared with 2019,the average groundwater depth decreased by 39.0%,and the lake surface area decreased by17.9%~42.3%during the same period in 2023;In the past 5 years(2019-2023),both the groundwater depth and lake surface area have been in a dynamic process of change.To improve the efficiency of ecological water use,a scientific direction for ecological water transportation is proposed.
