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 significance of the influence of many factors in the thermal environment around the water body, the orthogonal test design method is combined with the numerical simulation method of the outdoor thermal environment. Considering the fact that the water body itself is not changed, the layout, volume ratio, Influence of bank dike height, waterfront spacing and afforestation on water vapor diffusion and temperature in thermal environment around water body. Taking the average of the height of pedestrian in the residential area as the analysis index, the results show that the volume ratio, bank height and afforestation have the most significant impact on water vapor diffusion, and the minimum is the layout of buildings. For the temperature, there is no significant difference in the influence of various factors. Among the significant factors, the linear correlation of volume fraction to water vapor diffusion is high and the linear correlation to temperature is low. The effect of bank height on water cooling effect is obvious, and the impact on water vapor diffusion is relatively small.
