Embodiment Construction

[0029] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0030] At present, in the existing research on ecological flow, there are many calculation methods of ecological flow, and the ecological protection goals and water demand in these methods are not clear. Therefore, this application constructs ecological flow zoning, The "four-point" ecological flow allocation method of ecological protection target classification, different water seasons and horizontal year stages, and implem...

Abstract

The invention discloses a basin ecological flow accounting method. The method comprises the steps of S1, establishing an ecological flow management system model; S2, performing automatic division on the ecological flow management system model through an automatic partition division method to obtain each ecological flow partition; S3, calculating an ecological flow component of each ecological flow partition through a classification calculation method, establishing staged and classified ecological flow components of each ecological flow partition; S4, according to the staged and classified ecological flow components of each ecological flow partition, establishing partitioned, staged, classified and graded ecological flow standards; and S5, calculating the ecological flow of each ecological flow partition of the research basin according to the water supply, consumption and displacement and the partitioned, staged, classified and graded ecological flow standard of the research basin. The method solves the problems of high regulation and control of water engineering, water resource shortage, serious water pollution, large river form change and serious water ecological degradation in the existing basin.

Description

technical field [0001] The invention relates to the technical field of environment and ecological hydraulics, in particular to a method for calculating ecological flow in a river basin. Background technique [0002] The problem of over-exploitation of water resources and water pollution in the basin is very serious. The river course is cut off, the ecosystem is degraded, the hydrological conditions of some river sections have undergone fundamental changes, and the ecological function of the river is almost completely lost. The shortage of water resources in the basin and the unreasonable development and utilization of water resources have caused the The amount of ecological water is seriously insufficient. [0003] Existing river basins are highly regulated by water conservancy projects, water resources are in short supply, water pollution is serious, river forms have changed greatly, and water ecology has been seriously degraded. How to adjust the water use structure and pr...
