Early-warning prediction method for water environment safety

Abstract

The invention discloses an early-warning prediction method for water environment safety, which comprises the following steps: performing space-time multi-dimensional analysis on monitoring information acquired from a water environment; establishing a hazard rating threshold early-warning index according to the data acquired by the model analysis to form water environment safety early-warning rating and warning-situation comprehensive assessment data; and establishing a water environment safety early-warning basic database and gradient and abrupt early-warning prediction system models of the water environment safety, and establishing a data adapter between the water environment safety early-warning basic database and the early-warning prediction system models so as to visually express the prediction results of the models and implement full-process monitoring for the early-warning evolution of the water environment safety. Aiming at the complexity of the water environment and the multi-source isomerism of the water environment monitoring information, the method establishes an effective environment monitoring multi-source isomeric data fusion technology framework and a method to form an early-warning prediction system of the water environment safety so as to provide important theoretical direction for water environment management, and the method has broad application prospect.

Description

technical field [0001] The invention belongs to the field of water environment safety early warning, in particular to a water environment safety early warning prediction method based on multi-source heterogeneous monitoring information fusion. Background technique [0002] With the rapid development of social economy and the rising pressure on resources and environment, the safety of water environment has been seriously threatened, and many factors and areas of environmental insecurity have emerged. If the ability of early warning and forecasting cannot keep up, it may be caught off guard in the event of sudden pollution incidents, unable to deal with them, delaying the opportunity of war, and bringing serious threats and damage to the lives, health and safety of the people, the operation of economic life, social stability and environmental security. , and even cause major social impact. [0003] As the "sentinel" and "eyes and ears" of water environment management, environ...
