兼顾景观功能的人工湿地植物配置模式探讨

湿地植物是人工湿地的重要组成部分,在水质净化过程中起着非常重要的作用,同时也是形成湿地景观的重要要素,目前人工湿地植物的配置还存在着功能结构单一、种间搭配不合理、季相效果差、岸带植物配置效果不佳等问题,影响植物的生态功能及景观效果。通过对湿地植物群落结构特征的研究,借鉴园林中植物造景,提出将植物净化功能与景观特性相结合的设计构想,并提出空间尺度与时间尺度相结合的植物配置模式及将人工湿地的水体与岸带植物配置相结合的人工湿地植物景观设计方式,这将有利于充分发挥人工湿地的多功能效益。

Models of Deployment of Wetland Plants in Constructed Wetland Considering Landscaping Function

The presence of wetland plants is one of the most conspicuous features of wetlands. Wetland plants growing in constructed wetlands have several properties in relation to the treatment process that make them an essential component of the design. It is also an important part of wetland landscape. There are a few remaining issues, particularly in relation to the simplicity of the system structure and function, the irrational composition of species, the poor seasonal outlook, and inappropriate combinations of riparian plants etc. By analyzing the characteristics of natural vegetation of wetland and learning from the plant landscaping in gardening, the functions of purification and landscaping of the plants were combined together in the wetland design. The objective of this paper is to propose a model of plants deployment integrating both spatial and temporal considerations and a new landscape design combining water body and plant deployment for constructed wetland.
