城市生态环境质量调控能力设计——以北京市温榆河生物通道设计为例

Design of Control Ability of City Ecological Environmental Quality: A Case of Beijing Wenyu River Biological Corridor

以北京市温榆河生物通道设计为例,提出建设生态城市的关键是提高城市自身的环境质量调控能力,其设计应注重2个方面:①把以植物为主体的、具有合理异质性并达到一定面积的自然组分作为控制性组分,并保证其持久存在;②要保证"物种流"在城市景观内的顺畅流动。

Taking the design of Beijing Wenyu River biological corridor as an example,the authors put forward that the key of building an ecological city is to improve the city's control ability of environmental quality.There are two aspects that should be highlighted in the design.On one side,the natural component with the plants as the main body,with proper heterogeneity and with some amount of area should be regarded as controlling component and be kept existing persistently.On the other side,the 'species flow' should be guaranteed to move smoothly in the city landscape.
