基于ENVI-met的北京典型住宅区微气候数值模拟分析
Numerical simulation of microclimate in Beijing typical residential area based on ENVI-met model
摘要
Abstract
Based on an ENVI-met three-dimensional microclimate model,a numerical simulation model in a typical residential area of Beijing under the actual situation and roof greening conditions was established and microclimate characteristics were simulated.The results show that the simulated value is similar to the observed one after multi-ple parameter calibration for the ENVI-met model,and the model could reflect the micro-scale climate distribution characteristics.Roof greening significantly decreases temperature and increases humidity.Mean temperature in the study area decreases by 2-3 ℃ after roof greening;relative humidity increases by 2 .7%;wind speed falls by 0.34 m·s-1 ,and its range decreases from 0.40-1 .1 1 m·s-1 to 0.32-2.70 m·s-1 .The ENVI-met model could be used in the microclimate simulation and assessment by an effective three-dimensional model,which could provide scientific information for the local microclimate design and urban planning.关键词
