Abstract

The invention discloses a construction method of a south-China model of watershed hydrology forecasting without data. An existing model is split according to a physical process, then all dominant modules which are suitable for a study area or object are preferably selected from split or accumulated modules, or a modeling environment is utilized to construct new modules, then module fusion is carried out for a physical process of study on the basis of an internal coupling mechanism of the modeling environment, or imperfect modules in the existing model are replaced, and model reconstruction orimprovement is realized. At the same time, the method can be widely applied to studying responses of surface water quality to climate changes, and is especially suitable for use in analysis of responses of Hetao-region surface water quality to the climate changes.

Description

technical field [0001] The invention relates to a method for constructing a model, in particular to a method for constructing a hydrological forecasting model of a watershed without data in South China. Background technique [0002] The existing integrated modeling framework has insufficient management and development capabilities for models, and the object-oriented is not clear, and there is a lack of organic coupling of data, methods, models, visualization, etc., which brings a lot of inconvenience to model construction, operation, evaluation and application. In addition, the integrated modeling environment lacks support for high-performance computing, and its operating efficiency is low. With the development of observation technology, computer technology, network technology and high-performance computing, it is necessary and urgent to maximize the use of information technology and establish an integrated watershed modeling environment that makes full use of information te...
