Watershed water environment safety early warning method and watershed water environment safety early warning system

Abstract

The invention provides a watershed water environment safety early warning method and a watershed water environment safety early warning system. The method comprises the following steps of performing investigation, analysis and selection on models according to model characteristic factors, wherein the models include a social economy and resource utilization model, a land utilization prediction model and a watershed non-point source pollution load simulation model and a watershed water environment hydrodynamic water quality simulation model; performing integration on the selected models; performing simulation and prediction on the water environment by using research area environment data and using the integrated models to obtain the prediction result; and performing early warning judgment according to the prediction result and providing warning information. By setting the social economy and resource utilization model, the land utilization prediction model, the watershed non-point source pollution load simulation model and the watershed water environment hydrodynamic water quality simulation model and performing selection and integration on the models, the adaptation to different scenes, environments and requirements can be realized; the water environment safety early warning can be comprehensively and integrally generated; and the stability and the accuracy of the water environment safety early warning are improved.

Description

technical field [0001] The invention relates to the technical field of water resource control and management, in particular to a method and system for early warning of water environment safety in a river basin. Background technique [0002] In recent years, with the frequent occurrence of various water pollution accidents, foreign scholars have begun to pay attention to the early warning model research of water environment safety. etc. more representative. These early warning systems have been applied in the emergency treatment of many water pollution incidents, reducing the impact of water pollution accidents. Since the 1990s, domestic scholars have gradually explored the theoretical system and technical means of early warning of water environment safety. Among them, the research on early warning models also mainly focuses on the early warning needs of sudden risks, and mostly adopts a single water quality simulation model, focusing on realizing the simulation function of...
