夏热冬冷地区城市住宅区气候适应性规划设计比较研究

A COMPARATIVE STUDY OF CLIMATE-ADAPTIVE PLANNING AND DESIGN OF URBAN RESIDENTIAL ZONES IN HOT SUMMER AND COLD WINTER AREAS

夏季居住区内部的局部热岛效应导致的居住区室外空间高温问题,不仅影响居民的户外气候舒适感,也间接对其周边的城市环境气候产生作用。选取洛阳市洛河南岸新城区牡丹大道中段的4个住宅区进行气候数据采样,同时利用ENVI-met气候数值模拟技术对住宅区微气候进行模拟计算,比较在城市中心区相同气候环境下,不同规划布局和建筑空间布局的住宅区室外空间气候环境特征的差异性,以期为城市的气候适应性住宅区规划设计建设提供科学依据。

The high temperature outside caused by the local heat island effect inside the residential area in summer not only affects outdoor residents＇ comfort,but also indirectly affects environment and climate in the surrounding areas. The climate data were collected in 4 residential areas in the middle section of Peony Avenue of the new district on the southern bank of Luohe river in Luoyang city,and the simulated calculation was carried out for the residential microclimate with the ENVI-met climate numerical simulation technique. In addition,the differences in climate and environment outside the residential areas with different planning layouts and spatial layouts in the same climate and environment of urban center district were compared,with a view to provide a scientific basis for planning,design and construction of urban climate-adaptive residential areas.
