    城市景观水体水景效应与水质保育的协同途径

    摘要:城市景观水体是现代景观设计的重要组成部分,但由于其自身水动力学的特点及各种外源污染的影响,使得中国城市景观水体富营养化普遍严重,藻华时有发生。当前景观水体设计及管理对水质控制技术与方法关注不足,而现行的水质保育技术往往对景观水体的形式、流态及规模等特征重视不够,缺乏对水景效应和水质保育的协同性考虑,从而影响了景观水体观赏价值和生态功能的有效发挥。根据景观水体的水质特征,就环境学科水质控制技术与景观学科的观赏及人文要素融合开展探索,为当前中国环境现状特征下的城市景观水体建设、改造与管理提供参考与借鉴。

    Abstract:Urban landscape water is an important part of modern landscape design. However, its hydrodynamic characteristics and various effects of exogenous contamination lead to the widespread severe eutrophication and frequent algal blooms in China. The current water landscape design and management attaches insufficient importance to water quality control, and the existing water conservation techniques pay inadequate attention to the characteristics of landscape water such as form, flow pattern and scale. The lack of synergistic considerations of waterscape effect and water conservation makes neither ornamental value nor ecological functions effective. The features of existing water conservation techniques are analyzed based on landscape water quality characteristics. The exploration, consolidating the research and practice of Shanghai World Expo and the State Water Project on landscape water quality control, is carried out to the fusion of environmental water quality control technology and landscape ornamental and human elements. The reference is provided for the construction, transformation and management of urban landscape water under the current environmental status in China.
