干旱区农业灌区水资源管理是管理者和决策者面临的重大挑战。在其中一些地区，修建了许多池塘，以确保灌溉用水充足。因此，水库和池塘应联合管理，以尽量减少缺水。在这项研究中，一个新的集成的数学模型的联合，或集成，水库和池塘的运作，以最大限度地提高供水已被提出为一个纪念碑池塘灌溉系统。这一目标是通过使用两个模型实现的：一个是用于确定水库最佳流量的优化模型，另一个是考虑池塘和水库的调节作用并模拟其向灌溉系统供水的模拟模型。采用自适应遗传算法求解非线性、多维水库群优化问题。这种方法已被应用到叶尔羌河流域，以证明其适用性，并提出了三个方案。叶尔羌河流域模拟优化模型的主要目标是在塔里木河生态调水的约束下，最大限度地减少9个支渠系统的灌溉不足。模型的优化效果在第三种情景下尤为突出，即，XBD、MMK和ART水库和16个池塘联合运行，以满足YKB的用水需求。农业需水满足率高达75%，生态需水满足率为50.98%。研究结果表明，在干旱区灌溉系统中，水资源的联合利用方式是重要的。
Water resource management in arid agricultural irrigation regions is a great challenge for managers and decision makers. In some of those regions, many ponds have been built to ensure an adequate water supply for irrigation. Therefore, reservoirs and ponds should be managed conjunctively to minimize shortages of water. In this study, a new integrated mathematical model of conjunctive, or integrated, operation of reservoirs and ponds to maximize the water supply has been proposed for a reservoir-pond irrigation system. This objective has been achieved via the use of two models: an optimal model, which is used to determine the optimal discharge of reservoirs, and a simulation model, which considers the regulatory role of ponds and reservoirs and simulates their water supply to the irrigation system. An adaptive genetic algorithm has been employed in this study to solve the nonlinear and multi-dimensional reservoirs optimization problem. This methodology has been applied to the Yarkant River Basin to demonstrate its applicability, and three scenarios are presented. The main objective of the simulation-optimization model in the Yarkant River Basin is to minimize shortages in meeting irrigation demands for nine sub-irrigation systems subject to the constraint of ecological water transfer to the Tarim River. The optimizing effect of the model was particularly prominent under the third scenario, i.e., the XBD, MMK, and ART Reservoirs and 16 ponds conjunctively operated to meet the water demand of the YKB. The frequency of success (FS) in meeting agricultural water demands reaches up to 75%, and the value for ecological demand is 50.98%. The results demonstrate the importance of the conjunctive combined use approach for management of water resources in irrigation system of arid regions.
