中文摘要： 塔里木河下游生态安全与治理是以水过程为主线，水是塔里木河下游生态脆弱区最关键的生态因子，地下水成为维系荒漠河岸林植物生长的惟一水源。因此，开展塔里木河下游荒漠区断面尺度水循环过程模拟和模型研究，对水资源管理具有重要意义。地表水-地下水-土壤水转化过程和荒漠河岸林耗水过程模拟是面临的两个关键问题。项目将①定量识别断面尺度水循环耦合模型衔接的共同变量，提出断面尺度水循环过程算法；②以基于水热物理过程的SHAW模型为平台，融合集成地表水-地下水-土壤水转化过程算法，建立干旱区断面尺度水循环过程模拟的SHAW-SGS耦合模型，并用该耦合模型模拟间歇性生态输水条件下塔里木河下游典型断面的水循环过程。 这将进一步提升自然植被生态耗水量的计算精度，发展SHAW模型的二次开发，将在生态学和水文学交叉领域对干旱区生态水文学的发展做出贡献。

英文摘要： Ecological safety and comprehensive treatment with water as the main line in the lower reaches of Tarim River. Water is the key ecological factors, groundwater is the only water resources to maintain the desert riparian forest growth. Therefore the research on simulation of water cycle process of desert area in the lower reaches of Tarim River are important to the water resources management.The simulation of surface water- groundwater-soil water exchange process and simulation of section-scale water cycle process in the lower reaches of Tarim River are the two key topic.. This study, firstly, will quantitative identification convergence common variable between coupling interface, and will proposed the section-scale water cycle process method in the lower reaches of Tarim River. Secondly, this study intergrated surface water-groundwater-soil water exchange process model, establish a section-scale water cycle integrated SHAW-SGS model base on the SHAW model, and simulation the section-scale water cycle process under intermittent ecological water supply conditions in the lower reaches of Tarim River. That not only has iand improve the calculation accuracy of natural vegetation water consumption, and will improve the secondary development of SHAW model. This will further contribute to the development of eco-hydrology at the intersection of ecology and hydrology to arid areas.
