Method for constructing water eutrophication risk analysis model

The invention discloses a method for constructing water eutrophication risk analysis model, referring to a prediction/pre-warning method of water quality eutrophication risks. In terms of information technique, this invention includes: firstly creating Bayes network topology structure of water eutrophication risk analysis model via computer programmes in accordance with storage structure and stored content of respective monitoring data in water environment information system; analyzing various influencing factors and correlation causing the water eutrophication risks in adoption of parameter learning; lastly, generating a model via test and modification. Accordingly, the method of this invention takes various influencing factors and correlations thereof into consideration, thereby better analyzing degree of water eutrophication risk, realizing prediction/pre-warning of water eutrophication, and providing foundation of scientific decision to water environment management and water pollution control. As a result
