摘 要:为研究河流生态修复所需的补水量和补水关键期,以永定河官厅山峡段为例,采用环境需水量和生态需水量两种方法,计算不同阶段河流生态修复所需的生态水量。结果表明:水文变异后,永定河生态严重退化,实施生态补水迫在眉睫;现状1.7×10^8m^3补水水量具有一定的积极作用,但不能满足河流正常需水;未来3个典型年(75%、90%和95%)最低的生态补水量为4.88×10^8、6.11×10^8和6.37×10^8m^3,同时推荐3-6月份为生态补水关键期。通过对生态补水量和补水时机的研究,为永定河生态修复提供一定的理论依据。In order to study the water supplement amount and critical period of river ecological restoration,this paper takes the Guanting Shanxia Section of Yongding River as an example,and uses environmental water requirement and ecological water requirement methods to calculate the ecological water requirement of river ecological restoration at different stages.The results show that the Yongding River ecology is seriously degraded and the implementation of ecological water supplement is imminent after the hydrological variations.The current ecological water supplement of 1.7×10^8 m^3 has a certain positive effect,but it still cannot meet the normal water demand.The lowest ecological water supplement of the next three typical years(75%,90%and 95%)are 4.88×10^8,6.11×10^8 and 6.37×10^8 m^3,respectively.We recommend that the critical period of ecological supplement is from March to June.This research provides a certain theoretical basis for the ecological restoration of Yongding River.
关 键 词:水文变异 生态流量 生态需水量 生态修复 生态补水
