River lake water body quantity-quality coupling self-optimizing simulation regulation and control method

Abstract

The invention discloses a river lake water body quantity-quality coupling self-optimizing simulation regulation and control method which comprises the steps that first, a water body quantity-quality coupling simulation model in a river lake zone to be regulated and controlled is established; second, according to the water body quantity-quality coupling simulation model and a current decision scheme, the simulated results of the water quantity, the water level and the water quality of the river lake zone to be regulated and controlled are obtained; third, the water quantity, the water level and the water quality are used as decision targets, an optimization decision zone of a river lake water body system is established; fourth, whether the simulated results of the decision targets meet the requirement of the river lake water body system at the same time is judged, and the current decision scheme is corrected according to the judging results. According to the method, the water quantity, the water level and the water quality of a river lake water body are regulated and controlled in a combining mode, and accordingly water resource efficient allocation is achieved.

Description

technical field [0001] The invention belongs to the field of optimal allocation and control of water resources, and in particular relates to a self-optimization simulation control method for coupling the water quality of rivers and lakes. Background technique [0002] With the increasing frequency of global extreme climate changes and the increase in high-intensity human activities, water problems such as drought, floods, and water pollution have become increasingly severe, and have become one of the key factors restricting sustainable economic and social development. Establishing the most stringent water resources management system, maintaining the health of rivers and lakes, improving water resources emergency management capabilities, and realizing comprehensive management of water resources quantity and quality are being highly valued by governments around the world. At present, my country's ecological civilization development strategy has put forward new requirements for...

Problems solved by technology

However, the existing water quality and water quantity joint control technology lacks consideration of control objectives such as ecological flow and landscape water level in the objective function, and the model technology cannot meet the requirements of the most stringent water resources management system in practice for total water consumption, water use efficiency, and pollution-holding capacity. The demand for multi-objective management of "Three Red Lines"; nor can it adapt to the continuous changes in the environmental conditions of rivers and lakes such as hydrology, hydrodynamics, and sewage discharge, and adaptively regulate the operation mode of the storage and discharge control gate stations of rivers and lakes, which is difficult to meet the needs of different subjects. Water allocation, water level control, water quality management and other goals
