中文摘要: 针对概念性水文模型参数优化率定问题,以大、小径流过程对应的水文特性为切入点,考虑流域水文系统不同产汇流特性,提出一种多目标文化自适应仿电磁学算法(multi-objectiveculturalself-adaptiveelectromagnetism-likemechanism,MOCSEM)求解水文模型参数率定问题,并基于MOCSEM的优化结果,提出一种简便的自识别参数组合预报方法。在此基础上,将MOCSEM算法应用于概念性水文模型——新安江模型的参数多目标优化率定,与其他算法进行对比分析,应用文中提出的自识别参数组合预报方法,尝试找到一种能权衡流域水文系统不同水文特性的自识别参数组合方式,可以为水文预报人员提供更为精确的流域径流预报方法。
Abstract:To obtain a successful parameter calibration of conceptual hydrological model,hydrological characteristics of large and small runoff process were chosen for considering different characteristics of generation and concentration.A multi-objective cultural self-adaptive electromagnetism-like mechanism (MOCSEM) algorithm was proposed to solve parameter calibration problem.The MOCSEM was tested,firstly,and applied to multi-objective parameters calibration of Xinanjiang model.After achieving satisfactory performance on parameters calibration problems,the self-identifying parameters combination forecast method was implemented for trying to find a self-identifying parameter combination mode.The results showed that the proposed method can provide more precise forecast results than a single parameter scheme for hydrological forecasters.
