Problems solved by technology

However, in the stage of research and implementation of ecological dispatch after the project is in operation, there is still a lack of systematic methods for evaluating the effect of releasing ecological flow, which has certain restrictions on rationally optimizing the ecological dispatch plan of water conservancy and hydropower projects and scientifically implementing ecological dispatch.

Embodiment

[0059] The Niger River is a primary tributary on the right bank of the Dadu River. It originates near Muzhi Village at the foot of Xiangling Mountain in Xide County. It flows from south to north through Buheimu, Shunhe, Meixiaoying, Ganluo and other places. About 1.0km downstream of Gegegoukou flows into the Dadu River, with a total length of 140km and a drainage area of ​​4062km 2 . The Niger River Basin can develop hydropower resources of 400,000 kW, and has convenient transportation and good location advantages. Several hydropower stations have been planned and constructed successively. Most of the hydropower stations that have been built on the Niger River are developed by water diversion. After the power station is completed and put into operation, a water-reducing river section will be formed between the dam sites. Relevant requirements were implemented in the process. During the review and evaluation process of the Niger River, the effect of ecological flow was evalua...

Abstract

The invention relates to the technical field of hydropower project environment protection, discloses a method for assessing ecological flow discharging effects of water conservancy and hydropower projects, and aims at optimizing and completing ecological scheduling schemes. The method comprises the following steps of: 1, determining an assessed reach range; 2, determining protected objects; 3, determining a standard that discharged ecological flows satisfy water demands of the protected objects; 4, determining weights of different protected objects in effect assessment; 5, analyzing whether the discharged ecological flows satisfy the water demands of the different protected objects or not; and 6, comprehensively assessing an ecological flow discharging effect. The method is suitable for evaluating the effect of ecologically scheduling the discharged flow process by water conservancy and hydropower projects, is capable of providing technical support for optimally adjusting discharged flow schemes and ecological scheduling experiment schemes of water conservancy and hydropower projects, and has practical significance for scientifically and effectively implementing ecological scheduling for water conservancy and hydropower projects.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering environmental protection, in particular to a method for evaluating the ecological flow discharge effect of a water conservancy and hydropower project. Background technique [0002] my country stipulates in laws, regulations, policy documents, etc. that the development and utilization of water resources must be balanced, production, domestic and ecological water use should be comprehensively balanced, and ecological environment water needs should be fully considered. When evaluating the environmental impact of water conservancy and hydropower projects, it is required According to the ecological water demand of the section, the corresponding discharge ecological flow plan should be drawn up. It is also necessary to combine the specific project characteristics. After the completion of the project, according to the ecological protection goals of the downstream section, further study and f...
