Urban river rubber dam group water ecological regulation and control method

Abstract

The invention discloses an urban river rubber dam group water ecological regulation and control method. The method comprises the following steps of respectively establishing an upstream and midstreamdistributed hydrological model and a downstream river channel plane two-dimensional hydrodynamic numerical model, namely a pollutant transportation numerical model, of an urban river to be regulated and controlled according to upstream and midstream gas meteorological elements and runoff data of the urban river to be regulated and controlled; carrying out river basin production confluence simulation and river reach water quantity and water quality simulation calculation under the downstream river reach rubber dam group scheduling condition according to a hydrological model and a lower river channel plane two-dimensional hydrodynamic numerical model, namely a pollutant transportation numerical model; carrying out change adjustment and model parameter optimization caused by climate change and environmental factors; and presenting the basin production and confluence processes in different historical periods. According to the method, the river rubber dam group water quantity scheduling model is established by taking a downstream river runoff process, downstream urban section water body self-cleaning capability and ecological base flow as the constraint conditions, so that the river downstream urban section rubber dam group water ecological optimization scheduling method is determined, the method is simple and reliable, and the calculation required data is fewer and is relatively easy to obtain.

Description

technical field [0001] The invention belongs to the technical field of urban ecological control, and in particular relates to a water ecological control method for rubber dam groups in urban rivers. Background technique [0002] With the rapid development of most cities and the increase of population, the urban ecosystem has become a topic that people are eagerly concerned about. The urban ecosystem is an ecosystem formed in the environment with population, buildings and structures as the main body. At present, almost all urban ecosystems are It is an artificial ecosystem, its energy and material operation is carried out under the control of human beings, and the living and non-biological environments in which the residents live have been artificially transformed, and it is a system of human self-domestication; the population, energy and material capacity of the city are large, High density, large flow, and fast operation are related to the active factors of social and econo...

[0002] With the rapid development of most cities and the increase of population, the urban ecosystem has become a topic that people are eagerly concerned about. The urban ecosystem is an ecosystem formed in the environment with population, buildings and structures as the main body. At present, almost all urban ecosystems are It is an artificial ecosystem, its energy and material operation is carried out under the control of human beings, and the living and non-biological environments in which the residents live have been artificially transformed, and it is a system of human self-domestication; the population, energy and material capacity of the city are large, High density, large flow, and fast operation are related to the active factors of social and economic development; it is an incomplete and open ecosystem, and material circulation and energy conversion cannot be completed within the system

Because the city is the center of a certain region, the city depends on the existence and development of the region, so the dependence of the urban ecosystem is very strong, and the independence is weak. Therefore, it is necessary to make effective research on improving the urban ecological system and determine the reasonable capacity of the urban ecology. and the formulation of a harmonious, stable and efficient urban ecosystem structure feasible plan and management technical measures, etc.; as the main factor of the urban regulation system, the urban river structure needs to be effectively simulated and studied, and the existing regulation system cannot simulate the climate Changes and man-made disturbances affect the process of watershed runoff production and confluence in different historical periods; currently there is no dispatching system for urban river rubber dam groups; the existing dispatching system has a complex structure, and the data required for dispatching model calculations are large and difficult to obtain, and it takes a long time to formulate a feasible dispatching plan
