【摘要】 在中、微观尺度的热环境模拟仿真中,逐小时气象数据的获取常需花费较大的人力物力.选择SOLWEIG模型,探索在气象数据部分缺失的情况下,结合空间几何信息和气象观测数据,对城市局部地区热环境的评估方法进行研究.以武汉市夏季为例,使用2组真实数据、拟合数据,模拟区域内平均辐射温度日平均值分布情况,同时对基于2组数据的模拟结果进行定性和定量的对比分析研究.研究表明,该方法缓解了逐小时气象数据缺失时的困难,在计算精度上偏差量小、偏差点数量少.最后验证了该模拟方法的有效性,为城市微环境的热评估提供了一种便捷有效的评估方法.更多还原

【Abstract】 In the simulation of thermal environment at the medium and micro scales, the acquisition of hourly weather data often takes a lot of manpower and material resources. In this paper, the SOLWEIG model is selected to explore the method of evaluating the thermal environment in part of the city, in combination with spatial geometric information and meteorological observation data when the meteorological data are partially missing. The summer of Wuhan is taken for example. The real data and the fitted data are used to simulate the distribution of the daily average mean radiant temperature. Meanwhile the qualitative and quantitative comparative analyses of the simulation results based on the two sets of data are carried out. The research results show that the method alleviates the difficulty of hourly meteorological data loss. Both the deviation of calculation accuracy and the number of deviation points are small, so as to verify the effectiveness of the simulation method and provide a convenient and effective thermal assessment method for urban micro-environment.更多还原
