摘　　要：基于微气候环境模拟技术,对北京宛平城现状夏季微气候环境进行模拟分析,在综合考虑风环境、热环境、人体舒适度以及空间现状条件、改造价值等基础上,对其划分出四类微气候空间,分析了各类微气候空间的特征,提出基于微气候环境改善的城市设计优化策略。针对改造潜力较大的第二类微气候空间及相邻建筑区域,设计了优化方案,并对优化方案微气候环境进行定量分析,对比评估优化前后的效果。在城市设计中引入微气候环境定量分析技术,将有助于为方案设计、调整与完善提供科学依据。Based on the microclimate environment simulation technology,this paper simulates and analyzes the current summer microclimate environment of Wanpingcheng in Beijing,and divides it into four categories based on comprehensive consideration of wind environment,thermal environment,human comfort,existing space conditions,and renovation value.Microclimate space unit,analyzes the characteristics of various microclimate space,and proposes an urban design optimization strategy based on microclimate environment improvement.For the second type of microclimate space and adjacent building areas with great renovation potential,an optimization scheme is designed,and the microclimate environment of the optimization scheme is quantitatively analyzed,and the effect before and after optimization is compared and evaluated.The introduction of quantitative analysis technology of microclimate environment in urban design will help to provide scientific basis for scheme design,adjustment and improvement.
