Embodiment 1

[0081] This example is an evaluation of the comprehensive regulation of water resources in the Taihu Lake Basin in 2013 with the goal of regulation of water supply and water ecological environment.

[0082] (1) Determination of evaluation indicators

[0083] Since this year's water resources scheduling is carried out based on water supply and water ecological environment goals, the two indicators of the discharge status of the discharge project and the representative station's over-insurance risk index for assessing the effect of flood control scheduling are not considered, and only the evaluation of water supply scheduling and watershed water quality in the basin is used. Indicators of ecological environment regulation. The evaluation indicators of water supply dispatching in the basin include: the ratio of water diversion volume and the water supply efficiency of the water diversion project reflecting the operation effect of the water diversion project, and the water level s...

Embodiment 2

[0108] This example is an evaluation of the comprehensive regulation of water resources in the Taihu Lake Basin in 2015 with the goal of flood control regulation.

[0109] (1) Determination of evaluation indicators

[0110] Since this year's water resource scheduling is carried out based on flood control objectives, while flood control scheduling needs to take into account both water supply and water ecological environment scheduling. Therefore, the evaluation indicators not only include the two indicators of the discharge status of the effluent project and the representative station over-insurance risk index for evaluating the effect of flood control operation, but also include the indicators for evaluating the water supply operation of the basin and the operation of the ecological environment of the watershed. The evaluation indicators of water supply dispatching in the basin include: the ratio of water diversion volume and the water supply efficiency of the water diversion ...

Abstract

The invention discloses a technical method for integrated regulation and evaluation of flood control-water supply-water environment improvement in a river basin, which belongs to the technical field of environment and ecological hydraulics. The present invention comprises the following steps: (1) constructing dispatching indexes for flood control, water supply, and water ecological environment improvement in the river basin; (2) establishing calculation methods for each dispatching index, and establishing evaluation standards for each dispatching index; (3) combining dispatching targets in different water regime periods of the river basin , using the AHP to obtain the weights of comprehensive dispatching indicators in different water regimes; (4) Forming a multi-objective comprehensive dispatching evaluation system for flood control-water supply-water ecological environment improvement in different water regimes. This technical method comprehensively considers the evaluation of basin flood control, water supply, and water ecological environment improvement scheduling. The scheduling index data is easy to obtain. The evaluation standard grades are divided into excellent, good, medium, poor, and poor. The index weight objectively reflects the multi-objective scheduling relationship. The invention can provide a more comprehensive and effective evaluation method for integrated watershed dispatching, and is beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of environment and ecological hydraulics, and in particular relates to a technical method for comprehensive scheduling evaluation of flood control-water supply-water environment improvement in a river basin. Background technique [0002] The scheduling of river and lake water conservancy projects in the basin is an important means to avoid flood risks and optimize the allocation of water resources in the basin. With the increasingly prominent conflicts between social and economic development and resources and environment in the basin, human beings pay more and more attention to environmental quality and living health, and put forward higher and more comprehensive requirements for water conservancy dispatching in the basin, and the purpose of water conservancy dispatching in the basin is gradually emerging. Changes, from the traditional unilateral development and utilization of military, shipping, water suppl...
