摘要
为明确生态补水对永定河滞洪水库的补水方案,通过水均衡法计算大宁调蓄水库向永定河滞洪水库生态补水期间地下水补水量,统计汛期降水量、补水前后地下水水质等数据,开展生态补水对永定河滞洪水库地下水的补给分析,用相关性分析法提出使滞洪水库地下水位保持稳定和上升的最优补水方案,并进行校验,结果表明,以4.48 m3/s的流量补水11d为保持地下水位稳定补水方案,以5.15 m3/s的流量补水16d为使地下水位上升的最优补水方案.研究成果对后续生态补水的补水方案提供参考.
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.
