北京城市局地空气温度时空变化特征分析
Temporal and Spatial Variation Characteristics of Urban Local Microclimate in Beijing
摘要
Abstract
At present, conflicts between urban development and climate environment are becoming increasingly apparent under rapid urbanization in China. The negative effects of urban heat island on living environment could be greatly mitigated by appropriate urban planning and landscape design strategies. Revealing the dynamic mechanism and controlling factors of urban outdoor thermal environment is the necessary theoretical preparation for regulating and controlling urban climate environment. Mobile survey was applied to investigate the space-time characteristics of local microclimate of Beijing Olympic Forest Park and the surrounding development. The results showed that apparent differences in air temperature existed between small-scale urban areas. Microclimate of urban areas was obviously influenced by both the conditions of vegetation and environmental parameters characterizing the immediate environment of the measurement sites. Temperature differences and its spatial distribution characteristics varied with the season and between day and night. Greater difference and clearer distribution of air temperature was observed at night. During this time, temperature in the park was apparently lower than that of the surrounding built environment. The park cool island effect was exhibited with the fact that the farther from the park, the higher the temperature. However, during the day, there was smaller difference and more complex distribution of air temperature. In general, the temperature differences of the four time periods in the study area complied with the order: winter night>summer night>summer noon>winter noon, which indicated that the local heat island intensity during night was greater than during daytime, and the winter night was greater than the summer night.关键词
