中文摘要: |
针对中国人类活动强烈的流域水循环特点,在二元水循环理论的指导下,以SWAT分布式水文模型为基础,进行了灌溉和人工耗、用水模块的开发和改进,构建了适用于此类区域的二元水循环模型。利用改进后的模型对天津市的水循环过程进行了模拟。结果表明,改进后的模型模拟的NASH效率系数从0.62提高到0.89,相关系数从0.79提高到0.91,比改进前有明显的提高。模型的构建和改进,对分布式水文模型在高强度人类活动影响流域的水资源、水环境研究和管理将起到积极的作用。 |
英文摘要: |
Based on the theory of dual-cycling water resources the agriculture management module and consumptive water use module of SWAT distributed hydrological model are developed and updated. The updated model is applied to analyze the water resources in the Tianjin City, China, in which the water cycling is strongly affected by human activities. The results show that the improved model significantly improves the Nash Efficiency (Ens) from 0.62 to 0.89 and the correlation coefficient is improved from 0.79 to 0.91. The improved model can be applied to the area with strong human activities. |
