Embodiment Construction

[0052] The content of the present invention is not limited to the content of the above-mentioned embodiments, and a combination of one or several specific embodiments can also achieve the purpose of the invention.

[0053] In order to illustrate technical scheme of the present invention in more detail, the present invention provides following embodiment:

[0054] 1. Water ecological risk early warning-decision research

[0055] 1.1. Model establishment

[0056] (1) The relationship model between socio-economic development and water environment based on system dynamics

[0057] The function of the Bayesian network model is to provide early warning of the water quality of the downstream section according to the water quality change data of the upstream monitoring points, and to provide early warning of the water ecological risk of the Nierji Reservoir based on the early warning results of the water quality change combined with the evaluation index system, thereby Realize the e...

Abstract

The invention discloses a method for building a Nierji reservoir water ecological risk early warning model through the fusion technology, and relates to a method for building a Nierji reservoir water ecological risk early warning model. A system dynamics decision-making module is adopted for risk early warning and decision making quantitative analysis, then a Bayesian network model is adopted for risk early warning and decision making quantitative analysis according to a quantitative analysis result, and therefore Nierji reservoir water ecological risk early warning and decision making are achieved. The Nierji reservoir water ecological risk early warning model is built, the system dynamics and the Bayesian network model technology are fused, quantitative advantages in early-warning and decision-making research are highlighted, and Nierji reservoir water ecological risk early warning and decision making are achieved. The accuracy of the model is verified based on comparison and analysis for current data, and the availability of the model is verified through early-warning research on relative risk source risks and decision-making research on control strategies.

Description

technical field [0001] The invention relates to a method for early warning model of water ecological risk in Nierji Reservoir. Background technique [0002] The function of the Bayesian network model is to provide early warning of the water quality of the downstream section according to the water quality change data of the upstream monitoring points, and to provide early warning of the water ecological risk of the Nierji Reservoir based on the early warning results of the water quality change combined with the evaluation index system, thereby Realize the early warning function, but when the water quality of the downstream section changes, the probability of abnormal water quality at the upstream monitoring point can only be deduced through the Bayesian network model, and the resulting schemes such as "controlling discharge" must be unspecific and unreasonable. precise. [0003] At present, domestic research on ecological early warning still mainly exists in the early warnin...
