摘　　要：为了有效分析水体周边热环境中多个因素的影响显著性,将正交试验设计方法与室外热环境数值模拟方法相结合,考虑水体自身状况不变的情况下,重点讨论建筑布局、容积率、岸堤高度、滨水间距和绿化对水体周边热环境中的水蒸气扩散及温度的影响。以住区内行人高度平面的平均值作为分析指标,结果表明:容积率和岸堤高度和绿化对水蒸气扩散的影响最为显著,最小为建筑布局。而对于温度,各因素的影响无明显差距;显著因素中,容积率对水蒸气扩散的线性相关度较高,对温度的线性相关度较低。岸堤高度对水体降温效应的阻碍作用较为明显,对水蒸气扩散的影响相对较小。In order to effectively analyze the significances of factors in thermal environment around water body,orthogonal test design has been made with numerical simulation to discuss affections of various factors on thermal environment especially on water vapor diffusion and temperature. The factors mainly discussed in this paper are building type,building floor area ratio,embankment height,distance from water body,and landscaping. The results showed that the building floor area ratio and embankment height were the most significant factors for the vapor diffusion,followed by landscaping and the building type had the minimum influence. For the temperature,all factors had no obvious gap. Besides,the building floor area ratio was strongly linear correlated to water vapor diffusion but poorly to temperature,while embankment height had the opposite tendency.
