植被结构对严寒地区城市居住区冬夏微气候的影响研究

城市绿地对于改善城市微气候、缓解城市热岛效应有重要作用，且不同的植物配置、绿地形态以及植被结构所产生的效果不同。以严寒地区典型城市哈尔滨为例，采用现场实测的方法，针对不同植被结构的居住区绿地进行冬夏两季微气候现场实测，对不同植被结构的微气候调节性能进行深入研究，比较分析不同植被结构影响下的空气温度、相对湿度和风速。结果表明：随着植被结构趋于复杂，植被对于冬季冷风的遮挡作用和夏季的降温增湿作用均随之增强。该研究为严寒地区城市居住区景观设计提供参考依据。

Influence of Vegetation Structures on Winter and Summer Microclimates of Urban Residential Areas in Severe Cold Regions

Urban green space plays an important role in improving the urban microclimate and alleviating the urban heat island effect. Different plant configurations, greenbelt forms and vegetation structures will yield different results. This paper takes Harbin, a typical city in the severe cold areas, as an example, adopts the field measurement method to observe the microclimates of the green space in residential areas with different vegetation structures in winter and summer. It carries out in-depth study on the regulation performance of different vegetation structures over the microclimate, and makes comparative analysis of the air temperature, relative humidity and wind speed under the influence of different vegetation structures. The result shows that as the vegetation structure becomes more complex, the shelter effect of vegetation on winter cold wind and the cooling and humidifying effects in summer are enhanced. The study provides a reference for the landscape design of urban residential areas in severe cold regions
