基于分布式水文模型BTOPMC的晋江流域水文循环模拟

SIMULATING HYDROLOGICAL CYCLE IN JINJIANG RIVER BASIN WITH BTOPMC

晋江流域所在福建省泉州市近年来经济社会发展迅速,水资源短缺已经成为制约该地区发展一个重要因素.开展水文循环过程模拟对把握该流域水资源时空演变规律,提高决策管理水平具有重要意义.本研究采用已在亚洲季风区多个国家广泛得到应用的BTOPMC(Block-wise use of the TOPMODEL with the Muskingum—Cunge routing method)分布式水文模型对晋江流水文循环过程进行模拟.模拟结果表明BTOPMC模型在该流域具有较好的适用性,具有为制定科学合理的水资源管理政策提供决策支持的潜力.

Quanzhou City in Fujian Province, where the Jinjiang River basin is located, is experiencing rapid economic growth. Water shortage has become a limiting factor for regional development. It is vital to simulate hydrological cycle to understand temporal and spatial variations in water resources and to improve decision-making process. A hydrological model widely used in Asian monsoon region Block-wise use of TOPMODEL with Muskingum-Cunge routing method （BTOPMC） was applied. It was found that model performance was satisfactory. This will provide precise information for more reasonable water resource management.
