湿地

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.

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。

Furthermore, the gist and method of calculating ecological pondage and ecological water requirement have been provided, and Zhalong wetland has been given.

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.

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。

The main mechanism of nitrogen in wetland systems is the action of microorganisms,while the removal efficiency will increase with the protraction of HRTin wetland,and also the action has a close relationship with the alternant changes of DO formed by the undee flowing.

湿地系统除氮的主要机制在于微生物的作用，随停留时间的延长湿地系统对氮的去除效率增加，且该作用与波形水流状态所形成的溶解氧交替变化有关。

A series of control measures were proposed, such as comprehensive pollution control, construction of decontaminated wetlands in estuarine area, construction of the ecological bank and lakeside wetland, removal of the purse net, dredging and restoring the topography of lake basin, vegetation restoration, ecological restoration and management, and so on.

提出了污染综合防治、河口强化净化型湿地建设、生态护坡与湖滨带湿地建设、湖区养殖围网拆除、清淤与湖盆形态修复、湖区植被恢复与生态修复和湖泊生态管理等一系列整治对策。

Alpine meadow and wetland,closely correlated with the amount of water stock in the riverhead of China,is the most important ecosystem of the Qinghai-Tibetan Plateau.This ecosystem is the primary support for the industrial and agricultural and the living using water in the middle east of China,which makes the conservation of alpine meadow and wetland in the Qinghai-Tibetan Plateau have importantly practical significance.

高寒草甸及湿地是青藏高原上最为重要的生态系统，它的状况直接关系到我国江河源头的蓄水量，也关系到我国中部和东部广大地区的工农业及人民生活用水，因此对青藏高原高寒草甸与湿地的保护具有重要的现实意义。

This paper presents the composition structure of plant biodiversity in Maqu, a county of Gannan Tibetan Autonomy Prefecture and located at the northeastern edge of the Qinghai-Tibetan Plateau. which is he riverhead of the Yellow River. With the analytic hierarchy process, the reasons of deterioration and the measurers of restoration are given.

本研究对青藏高原东北缘黄河源头地区甘南藏族自治州的玛曲县高寒草甸及湿地进行调查，揭示了该地区的植被生物多样性情况与组成结构，利用解析层次方法分析了高寒草甸及湿地的退化原因及恢复手段，同时还从集合种群竞争原理出发对该地区植被生物多样性的维持机理进行了讨论。

Salt marsh vegetation is one of the most important components of coastal wetlands, and its evolution and dynamics have direct influences on the ecosystem service and value of wetlands.

盐沼植被是滩涂湿地的重要组成部分，其动态变化直接影响着湿地的生态服务功能和价值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
