摘要
沼泽是最典型的湿地类型之一,具有重要的水文和生态功能,尤其是在生物多样性保护方面发挥着不可替代的作用。本文提出了沼泽湿地生态储水量的概念与内涵,界定了其与生态需水量的区别与联系,探讨了两者的计算依据与方法,并以扎龙湿地为实例进行了计算。根据生态储水量与生态需水量,可以确定沼泽湿地生态用水合理规模。实际用水配置中应以湿地系统的自然条件为基础,考虑生态功能需要,根据实际水资源丰枯情况,确定合理的补水规模,保证湿地储水量在时空尺度上合理变化,实现水资源的合理配置。
Marsh is one of the most typical wetlands, playing important roles in hydrological and economic aspects, especially in keeping biological diversity. In this study, the definition and category of the ecological pondage of marsh have been discussed for the first time, and the distinction and relationship with ecological water requirement have been analyzed. Furthermore, the gist and method of calculating ecological pondage and ecological water requirement have been provided, and Zhalong wetland has been given as an example of calculation of the two variables. Ecological water use of marsh can be ascertained according to ecological pondage and ecological water requirement, and the suitable quantity can be calculated basing on the marsh＇s water condition and the total water quantity, insuring that the pondage changes reasonably in spatial and temporal scale, so that the rational water allocation can be achieved.
