基于Monte Carlo模拟流量变异性对灌水质量影响的评价

Assessment of the Influence that Flow Variability on Irrigation Quality Based on Monte Carlo Simulation

为了更精确地进行灌区灌溉系统的设计与管理,基于Monte Carlo模拟方法模拟灌水流量的变异状况,借助SRFR灌溉模型评价灌水流量变异性对灌水质量的影响,并建立稳健度指标反映其影响程度。提出了合理有效的评价方法,并给出了灌区畦灌方式运行的评价案例。结果表明,灌水质量受灌水流量的变异性影响越大,灌水均匀度对灌水流量的敏感性大于灌水效率。稳健度指标数值越高,说明此流量变异性对灌水质量的影响程度低,稳健度达到80%以上,说明该灌水流量方案对于该区域灌水的应用性良好。

In order to design and manage irrigatiofi system more precise ,The article simulate variation of flow based on the Monte Carlo simulation method, With the help of SRFR irrigation model to evaluate that flow variability influence on irrigation quality , and establish robustness index to reflect the degree of influence. Put forward a reasonable and effective evaluation method, and gives the evaluated case of irrigation area operate by border method of irrigation.
