基于水资源优化配置的地下水可开采量研究

摘要：水资源开发利用格局改变将会导致地下水补排关系发生变化，针对此问题，本文通过系统分析水资源优化配置模型和地下水数值模拟模型的数据交互关系，将二者进行耦合迭代计算规划年地下水可开采量，并将其应用于新疆鄯善县。计算结果显示，随着规划年水资源优化配置及开发利用格局改变，当地地下水可开采量和超采量分别由现状年的23469万m³和18592万m³衰减到2030年的13730万m³和0万m³，较好地解决了规划年地下水可开采量的准确量化难题，可作为地下水资源开发利用和保护的依据。此方法可供其他类似地区参考和借鉴。

Study on exploitable quantity of groundwater based on water resources optimal allocation

Abstract: Changes in the pattern of the development and utilization of water resources will lead to the changes in the recharge and discharge properties of groundwater, Aiming at this problem, this article analyses the data interaction between water resources optimal allocation model and groundwater mathematical simulation model, and these models are combined to calculate the exploitable quantity of groundwater, applied in Shanshan county, Xinjiang region. With the changes of planning optimized allocation and development and utilization of water resources, calculation results show that the exploitation and overexploitation of groundwater can respectively decreased from 235 million m3 and 186 million m3 in present to 137 million m3 and 0 million m3 in 2030 year. This article solves the problem of accurately quantifying the amount of available groundwater successfully, and it also can be used as the basis for the utilization and protection of groundwater resources. This method can be available for other similar areas.
