摘要
地下水管理模型在水资源开发利用与管理中起着重要的作用,但由于地下水循环过程和作用关系极其复杂,从而导致相关模型的实际应用效果欠佳。针对地下水位与泉流量、河沟排泄量和地下水蒸发量之间的变化关系,建立了数学表达式,并将其嵌入到地下水系统模拟模型中,继而建立了含有协变量的非线性地下水优化管理模型。通过在典型的假想地下水系统中的合理性检验,认为所提出的理论和方法是正确的。
As groundwater cycle process and interaction relationship are extremely complicated,and it is difficult to describe the correlation model objectively,which resulted in poor application.An equation expressing the inherent connection between groundwater level and spring discharge,river discharge,evaporation of groundwater is developed,and is integrated into the mathematical simulation model of groundwater system,and on this basis,a nonlinear groundwater optimization management model with covariates is established.Through a rationality check for a typical hypothetical groundwater system,the correctness of the presented theory and method is verified.
