水文模型是人们认识水文循环过程,进行水文预报和水资源管理的重要工具和手段.在水文预报和水资源管理事务中,针对具体的预报和决策目标,需要根据研究区本身特征、各类数据现状,选择符合实际需求的水文模型.详细分析水文模型选择的必要性及其在水文建模及模型应用中的地位,在回顾水文模型选择研究现状基础上,总结水文模型选择的基本原则,并对各种水文模型选择方法进行分类,进而明确提出水文模型选择的概念,最后提出基于知识、水文模型特性及数据资料等相结合的综合水文模型智能选择框架,探讨水文模型选择的发展趋势.
The hydrological model is an important tool and means for people to know the hydrological cycle process, carry out hydrological forecasting and water resources management, and in the hydrological forecasting and water resources management issues, specific forecasting and decision-making goals need to be based on the characteristics of the study area, various types of data Based on the current situation of hydrological model selection, the paper chooses a hydrological model that meets the actual needs, analyzes the necessity of hydrological model selection and its role in hydrological modeling and model application, reviews the basic principles of hydrological model selection Then, the concept of hydrological model selection is put forward clearly. Finally, an intelligent selection framework of integrated hydrological model based on knowledge, hydrological model characteristics and data is put forward to discuss the development trend of hydrological model selection.
