Embodiment 1

[0051] A method for constructing a water body eutrophication risk analysis model, selecting relevant data such as water quality, hydrology, and meteorology of 10 primary tributaries in the Three Gorges Reservoir area for computer programming processing, and the specific steps are as follows:

[0052] (1) Construct the initial Bayesian network structure of water eutrophication

[0053] Based on the monitoring data of 10 first-level tributaries in the Three Gorges Reservoir area, analyze the mutual influence relationship between the monitoring data of meteorology, hydrology, water quality, algae growth, biochemical reaction, etc., and construct the initial Bayeux of water body eutrophication risk analysis The topological structure of the Sri Lankan network, that is, the initial structure such as Figure 2-7 shown.

[0054] (2) Construct the relationship model of monitoring data in the water environment

[0055] According to the scope of data monitoring in the water environment...

Abstract

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, this invention can be widely applied to water eutrophication risk analysis as well as prediction/pre-warning of rivers and lakes, in particular to water eutrophication risk tendency analysis and prediction of the Three Gorges Reservoir area.

Description

1. Technical field [0001] The invention belongs to the technical field of water environment safety prediction and early warning in reservoir areas, and in particular relates to a method for prediction and early warning of water quality eutrophication risks in reservoir areas. 2. Background technology [0002] The eutrophication of the water quality in the reservoir area will have a great impact on people's production and life, and it is necessary to strengthen the corresponding forecast and early warning work. However, the current evaluation and alarm of the monitored water quality belongs to the category of sudden early warning, and the data considered are limited to water quality indicators. In fact, the eutrophication of the waters in the reservoir area is a gradual process, and it is affected by various factors such as water quality, meteorology, and hydrology. The potential risk of eutrophication in the waters of the reservoir area can be discovered by analyzing histori...
