【摘要】 为简化水资源评价中还原计算的工作量,人们提出了利用水文模型进行水资源评价的方法,但近年来由于水资源开发利用对流域水文的影响,还原结果往往出现偏差。针对此问题提出了基于改进的垂向混合产流模型用于水资源评价的方法,考虑水资源开发利用的影响,建立水资源评价模型。参数优选则是在计算机自动优化的基础上进行人工优选,以增加参数精度。经案例分析表明,所建立的水资源评价模型适用于研究区的水资源评价,且以相对误差小于20%为标准,合格率达83.9%。为研究区水资源评价提供了新的方法。更多还原

【Abstract】 Because of the influence of water resources development and utilization,the result of water resources evaluation based on hydrological models often deviates. Based on the characteristics of hydrologic cycle under current conditions,an improved vertical mixed flow model is proposed for water resources evaluation. The model is established by considering the impact of water resources development and utilization. On the basis of computer automatic optimization,artificial optimization parameters are carried out to increase the precision of the parameters. Parameter optimization is based on automatic computer optimization to improve parameter precision. The results show that the water resources evaluation model is suitable for the water resources evaluation in the study area. The relative error is less than 20 %,and the qualified rate is 83.9 %. It provides a new method for the water resources evaluation in the study area.更多还原
