A shallow lake group water quality, water quantity and water ecological coupling scheduling analysis method

Abstract

The invention discloses a shallow lake group water quality, water quantity and water ecological coupling scheduling analysis method. The method comprises the following steps of 1) collecting researcharea data; 2) establishing a shallow lake group hydrodynamic model; 3) constructing a shallow lake group water quality model; 4) coupling of a hydrodynamic water quality model; 5) constructing a shallow lake group water ecological model; 6) constructing a shallow lake group hydrodynamic water quality and water ecological coupling model; 7) carrying out the parameter calibration of the model; 8) scheduling and analyzing. According to the analysis method, the regional water environment treatment scheme of water quality, water quantity and water ecological coupling dispatching is considered fromthe perspective of the whole lake group, the shallow lake group is dispatched, and the self-cleaning capacity of lake group water bodies can be utilized to reduce the pollutant concentration of a heavy pollution region to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of water environment protection, in particular to an analysis method for water quality, water quantity, and ecological coupling scheduling of shallow lake groups. Background technique [0002] Since the 1960s, the rapid economic development and rapid population expansion have led to a sharp increase in the demand for water resources. The development and utilization of lakes has continued to increase, the water quality of lakes has continued to decline, the water environment has become worse and worse, and the water ecological balance has been seriously damaged. Due to the shallow average water depth of urban shallow lakes, they are easily affected by the external environment and have poor ecological self-healing ability. The eutrophication problem of lakes is more prominent. [0003] At the same time, due to the large water area and complex shape of the lake, it is difficult for the introduced water flow to ...

Problems solved by technology

[0005] (1) The interaction between lakes is not considered;

[0006] (2) It is impossible to take into account the connection of lakes and the influence of water diversion on the hydrodynamic water quality of lakes, and it is impossible to accurately reflect the changes in the hydrodynamic water quality of lakes after water diversion, which will cause difficulties for decision makers to make reasonable adjustments;

[0007] (3) The ecological restoration of a single lake cannot use the self-purification ability of the entire lake group to improve the water quality;

[0008] (4) Only build water quality and quantity models for lakes, without considering the ecological conditions of lakes, and cannot understand the growth of phytoplankton and algae in lakes. The water quality of all lake water bodies cannot be accurately reflected, so as to effectively solve the problem of enrichment of lakes. Troubleshooting problems
