Water resource configuration method facing river channel ecological water requirement

Abstract

The invention discloses a water resource configuration method facing river channel ecological water requirement. The method comprises the following steps: in a water resource configuration model, a river ecological water requirement section is defined as an ecological unit; a relation between a water resource and the ecological unit is built; the constraint of the water resource configuration model is met; a virtual reservoir is set near the upstream of the ecological unit to form the water resource configuration model facing ecological regulation; the water consumption of the ecological unitis 0; the capacity of the virtual reservoir is 0; and in the ecological regulation process, the water resource configuration model facing ecological regulation regulates according to the following rules: the discharge water quantity of the upstream reservoir and the section gathering currents both enter the virtual reservoir; the inflowing quantity is firstly used for supplying water to the ecological unit, and redundant water is discharged; and if the water supply of the ecological unit is insufficient, a water regulation instruction is sent to the upstream reservoir for ecological water supply. The method realizes multi-purpose long-series simulation process, meets the demands of different water use objects, and achieves important significance on development of comprehensive reclamationof river basins and on formulation of basin ecological water supply schemes on the planning aspect.

Description

technical field [0001] The invention relates to the field of ecological dispatching, in particular to a method for water resource allocation oriented to the ecological water demand of river courses. Background technique [0002] Ecological scheduling is a general term for various river and water engineering scheduling measures implemented to rescue or restore damaged river ecosystems and promote the self-repairing capabilities of river ecosystems. Its essence is to incorporate ecological factors into existing reservoir scheduling and regional planning. Multi-objective comprehensive scheduling is carried out in the water resource allocation scheme. The usual practice is to fully consider the regulation performance of the reservoir and the characteristics of the river channel, use the reservoir capacity to store or release runoff in a timely manner to adjust the natural water and sediment process, improve the water environment conditions of the reservoir area and downstream ri...

Problems solved by technology

[0008] (1) The above-mentioned models can usually only calculate the ecological regulation of a single reservoir, rather than the calculation at the level of the whole basin;

[0009] (2) In terms of ecological flow constraints, only one of the constraint control type and the target control type can be selected, and the two constraint control methods cannot be considered at the same time, and both involve the reconstruction of the original water resource allocation model, the program Heavy development workload;

[0010] (3) The above-mentioned models can usually only simulate one target of river ecological flow, and cannot fully consider other socio-economic supply and demand processes in the basin, and the comprehensive effect of water resource allocation targets is not balanced
