Problems solved by technology

It does not take into account the dynamic relationship between artificial water use and engineering scheduling (artificial water source distribution) and the natural water cycle, and cannot reflect the general reality that factors such as artificial water intake and water conservancy engineering regulation change the runoff process and thus affect the pollution-holding capacity

Abstract

The invention discloses a water quantity and quality regulating method based on a water function area. The method includes constructing a water quantity regulating simulation model; calculating control section flow of the water function area; calculating pollution loading amount into a river; calculating pollutant-loading capacity based on the water function area; and analyzing a standard reaching status of the water function area. According to the method, the water quantity regulating simulation model of a basin level water function area is constructed; the relation between water consumption, project scheduling and natural water cycle is considered, simultaneously, a pollutant-loading capacity analysis model of the water function area is constructed and used, the pollutant-loading capacity of the water function area is analyzed according to the water quantity regulating simulation model, and the water quantity and quality of a basin is regulated according to the analyzing and calculating results. Compared with the prior art, the factors of water consumption, project scheduling and natural water cycle are fully considered, pollutant-loading capacity analysis of the water quality of the basin is more accurate, and the water quantity regulation is more reasonable.

Description

technical field [0001] The invention relates to a water quantity and quality control method based on water functional areas, which is a water resource control method and a method for analyzing the water quantity and water quality of river water function areas in areas or river basins of thousands of square kilometers or more and water environment control methods. Background technique [0002] The analysis and regulation of the ecological environment need to integrate many factors of the natural environment and human activities, eliminate the factors that have less influence, determine the key factors, and establish a model that is most similar to the actual river state. And in the application of the model, the model is continuously expanded and corrected, and more factors are added to make the model closer to the actual state of the river and water environment. Due to the limitations of the scientific research level and means at the time, the analysis of large-scale water q...
