Water environment bearing capacity evaluation method and device, equipment and medium

Abstract

The invention provides a water environment bearing capacity evaluation method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: determining an average available water resource quantity of a target river in a target time period according to an average runoff volume, an average sediment transport water demand and an average ecological water demand of the target river in the target time period; based on a preset water quality model, determining the average water environment capacity of the target river in the target time period according to the hydrological data of the target river in the target time period and the target value of the water background concentration of the target pollutant; and determining the water environment bearing capacity of the target river in the target time period based on the average available water resource quantity and the average water environment capacity. Subjective selection of data indexes is avoided, quantitative calculation of the water environment bearing capacity is achieved, and calculation and verification are simplified.

Description

technical field [0001] The invention relates to the technical field of water resources and environment, in particular to a method, device, equipment and medium for evaluating water environment carrying capacity. Background technique [0002] The water environment carrying capacity represents the ability of the basin water system to provide human beings with the total amount of water resources available and absorb water pollution. It determines the development of the regional population and economic scale, and is also an important scientific basis for formulating water resource allocation plans and sustainable development plans for the basin. [0003] At present, the main research methods of water environment carrying capacity include index system evaluation method, principal component analysis method, multi-objective model optimization method, system dynamics method and artificial neural network method, etc. However, there are still the following limitations in the relevant ...

AI Technical Summary

Problems solved by technology

However, there are still the following limitations in the relevant research on the evaluation of water environment carrying capacity: (1) When constructing the evaluation system, the selection of indicators is easily influenced by the selector; (2) The determination of parameter classification standards and the selection of principal components and control points (3) The calculation and verification process of water environmental carrying capacity is relatively complicated
