马岭水利枢纽下泄生态流量分析研究
Ecological Flow Discharge of Maling Water Control Project
摘要
Abstract
Ecological flow is one of the essential measures for ecological environmental protection in water conservancy and hydropower projects.This study focuses on the downstream river section of the Maling Water Control Project in Guizhou Province to analyze the channel's water use demands.Methods such as hydrological,hydraulic,and eco-hydraulic approaches were employed to estimate water requirements for various demands.After integrating all water use demands,the ecological flow release scheme is determined as follows:A minimum discharge of 4.26 m³/s must be maintained year-round at the dam site.From May to October,a minimum discharge of 15 m³/s must be ensured.When inflow volumes fall below 15 m³/s,the discharge should match the inflow volume.During dry years when the reservoir cannot meet water supply requirements,the discharge shall not fall below 4.26 m³/s.The research findings provide a basis for maintaining the aquatic ecosystem and sustainable use of water resources in the river reach downstream of the Maling Water Conservancy Project dam,and offer a reference for determining the ecological flow of rivers in southwestern mountainous areas.关键词
