摘要
Abstract
In order to clarify the ecological replenishment plan for the Yongding River flood detention reservoir,the water balance method was used to calculate the amount of groundwater replenishment dur-ing the ecological replenishment period from the Daning regulating reservoir to the Yongding River flood detention reservoir.The precipitation during the flood season,groundwater quality before and after replen-ishment,and other data were collected to conduct an analysis of the ecological replenishment of groundwa-ter in the Yongding River flood detention reservoir.The correlation analysis method was used to propose the optimal replenishment plan for maintaining stable and rising groundwater levels in the flood detention reservoir,and verification was carried out.The results indicate that a flow rate of 4.48m3/s for 11 days is the optimal replenishment plan to maintain stable groundwater levels,and a flow rate of 5.15m3/s for 16 days is the optimal replenishment plan to raise groundwater levels.The research results provide reference for the subsequent ecological water replenishment plan.关键词
