The sustainable utilization of water resources is a focal point in the field of global ecology and the environment, especially in arid and semi-arid regions. As a crucial means of water resource regulation, research into the evolutionary mechanisms of lake hydro-ecological environments is vital for maintaining water volume and ecosystem health. The Aidar-Arnasay Lakes System (AALS) is the largest lake system in Uzbekistan. Due to its relatively short formation history, unclear formation mechanisms, and uncertain impacts on the surrounding water environment, the sustainability of the AALS presents significant uncertainty. Therefore, it serves as a typical case for studying the causes and evolutionary patterns of lake hydro-ecological environments.

　　This project employs an interdisciplinary research approach, integrating stable isotope techniques, remote sensing image analysis, in-situ observations, and model simulations. It aims to thoroughly investigate the formation causes, hydrological cycle processes, and resulting environmental effects of the AALS. On this basis, the project will quantify the dynamic changes in the lake's water quantity and quality, predict future trends, and analyze resource sustainability. The research seeks methodological innovations and breakthroughs in the evaluation of lake hydro-environmental evolution and water resource sustainability, providing a scientific basis and decision-making support for the protection and sustainable use of lake water resources.

　　The study area is located in Uzbekistan, along the Belt and Road route. The findings will also offer scientific support for other arid-region Belt and Road countries to identify water environmental issues and achieve sustainable water resource management. Furthermore, the project promotes international youth exchange and cooperation, driving technological innovation in global water resources. By providing new perspectives and technical means for lake water resource management, this project contributes to global research and practice in the sustainable utilization of water resources.
