【摘要】：基于三维微气候模拟软件ENVI-met,以北京典型住宅区为研究对象,建立实况及设有屋顶绿化两种场景下的三维数值模拟模型,对研究区的微气候特征进行模拟分析。结果表明:微气候ENVI-met模型经过多次参数校正后,模型模拟结果与实测结果较接近,能较好反应微尺度气候的分布特征;屋顶经过简单的绿化后具有较好的降温增湿效果,使研究区平均温度降低了2—3℃,相对湿度增加了2.7%,风速由0.32—2.70 m·s-1降低至0.40—1.11 m·s-1,整体下降了0.34 m·s-1。ENVI-met通过三维模型可有效地应用于微气候模拟评价中,对评估当地微气候设计和城市规划具有一定的应用性。
[Abstract]:Based on the 3D microclimate simulation software ENVI-metand taking typical residential area in Beijing as the research object, a three-dimensional numerical simulation model was established under the two scenarios of real situation and roof greening, and the characteristics of microclimate in the study area were simulated and analyzed. The results show that the simulation results of the microclimate ENVI-met model are close to the measured results and can reflect the distribution characteristics of microclimate, and the roof has a better effect of cooling and humidifying after simple greening. The average temperature of the study area is reduced by 2-3 鈩，
