浙东古村落广场风环境模拟检验方法研究——以马头村法治广场为例

Research on the Simulation Test Method of Wind Environment in Ancient Village Square in Eastern Zhejiang--A Case of Fazhi Square in Matou Village

风环境模拟是提升古村落公共空间微气候的重要手段。以马头古村法治广场为例,经调研对象确立、实测仪器选择、选点分布制定、气象数据采集、模拟边界设定、实测与模拟结果相关性检验等步骤,总结出适用于浙东古村落的广场风环境模拟检验方法。结果表明:360°风速风向仪能有效解决单风向测试风速导致数据不准的问题;应拓展广场范围,通常为外围建筑和街巷(弯曲后形成较围合空间)的外边界;应在Sketchup等软件中依据树形单独建模;可采用配对样本t检验来进行实测与模拟数据对比验证。

Wind environment simulation is an important mean to improve the microclimate of the public space of the ancient villages.This paper takes the Fazhi square in Matou village as an example.The paper carries out several steps,including establishing the research object,selecting the instrument,formulating the actual measurement points,collecting meteorological data,simulating the setting of the boundary,measuring and testing the correlation of the measured results,etc.,and summarizes the wind environment simulation test method for the square suitable for the ancient villages in eastern Zhejiang.The result shows:The 360°anemometer can effectively solve the problem of inaccurate data from a single wind direction;the scope of the square should be expanded,and it is usually the outer boundary of the surrounding buildings and streets(which form a more enclosed space after bending);the model should be created separately in the Sketchup software according to the shape of the tree;paired-sample t-test can be used to compare and verify the actual measured and simulated data.
