摘要: 在中国城市高密度开发的用地模式下，依靠城市内部的有限绿地很难达到空气净化的自平衡。城市周边的绿地、水体等绿色基础设施在提供清洁空气、消解空气污染物、调节城市气候中发挥着重要作用。论文从调节城市空气质量的视角切入，以哈尔滨为研究案例，以ArcGIS为数据分析平台，提出市域尺度下城市绿色基础设施识别的方法：1）空间单元识别：以局地环流理论为依据，根据地表覆盖与植被类型数据，识别出绿色基础设施的3类空间单元；2）城市风场分析：通过对一年四季典型月份的气象统计和基于风环境模拟软件CALMET的风场模拟，得到哈尔滨的典型月份风环境图；3）空间体系表达：根据城市风环境图，分析绿色基础设施在调节城市空气中发挥的作用，得到GI的空气调节空间分布体系。研究成果可以作为编制城市绿地系统规划和制订区域生态绿地保护策略的依据，并在城市风环境分析、城市风道规划等领域得到进一步应用。Abstract: Under the high-density development land use patterns in China, it is difficult to achieve the self-balance of air purification relying on the limited green space inside the city. Green patches, water patches and other ecological patches around the city play an important role in providing clean air, dispelling air pollutants and regulating the urban climate. From the perspective of regulating urban air quality, taking Harbin as a study case, this paper proposes a method of urban green infrastructure spatial schema recognition and translation at the city scale based on the analysis platform of ArcGIS: 1) Basic identification: Relying on the local circumfluence theory, three types of spatial units of green infrastructure are identified according to the data of land cover and vegetation types. 2) Urban wind field analysis: through the meteorological statistics of typical months of the year and the wind field simulation based on CALMET software, the typical monthly wind environment map of Harbin is obtained. 3) Spatial schema translation: the role of green infrastructure in regulating urban air is analyzed according to the urban wind environment map to obtain the air conditioning spatial schema of GI. The research results can be used as the basis for the planning of urban green space system and the formulation of regional ecological protection strategies, and further application in the urban wind environment analysis and urban air duct planning.
