摘要: 探讨不同颜色水泥透水砖在不同园林环境下的砖表面温度,对于改善干旱半干旱地区园林微气候具有重要意义。以兰州城市公园常用的黑、红、黄、绿4种颜色水泥透水砖为研究对象,并以青石板为对照(CK),开展室内光照模拟实验及户外不同阴影条件下(无阴影、半阴影和全阴影)的实验。结果表明:(1)室内光照模拟实验表明,透水砖颜色越深,其表面温度越高,热流与表面温度呈正相关关系。(2)无阴影实验表明,各砖表面最高温度分别为63.7、63.4、61.5、53.5、54.2℃,平均热流分别为236.7、196、166.9、162.2、149.1 W/m2。(3)半阴影实验表明,各砖表面最高温度分别为45.4、45.4、41.7、39.7、40.1℃,平均热流分别为55.7、67.1、39.3、24.6、28.6 W/m2,相较于无阴影实验,各砖表面温度和热流均明显降低。(4)全阴影实验表明,各砖表面最高温度分别为31.2、30.9、30.5、30.4、30.1℃,平均热流均低于0 W/m²,相较于无阴影实验,各砖表面温度和热流均显著降低。依据透水砖颜色深浅并结合阴影布局进行合理设计,有助于改善干旱半干旱地区的园林微气候。

Abstract:

The study of the surface temperatures of permeable cement bricks in different colors under various landscaping environments is of significant importance for improving the microclimate in arid and semi-arid regions. This research focuses on four commonly used colored permeable cement bricks (black, red, yellow, and green) in Lanzhou Urban Parks, with slate as the control (CK). Both indoor light simulation experiments and outdoor experiments under different shading conditions (no shadow, semi-shadow, and full shadow) were conducted. The results indicated that: (1) the indoor light simulation experiment showed that the darker the color of the permeable brick, the higher its surface temperature, and there was a positive correlation between heat flux and surface temperature. (2) In the no-shadow experiment, the highest surface temperatures for the different bricks were 63.7, 63.4, 61.5, 53.5 and 54.2℃, with average heat flux values of 236.7, 196, 166.9, 162.2 and 149.1 W/m2, respectively. (3) In the semi-shadow experiment, the highest surface temperatures for the different bricks were 45.4, 45.4, 41.7, 39.7 and 40.1℃, with average heat flux values of 55.7, 67.1, 39.3, 24.6 and 28.6 W/m2, respectively. Compared to the no-shadow experiment, both the surface temperatures and heat flux were significantly lower. (4) In the full-shadow experiment, the highest surface temperatures for the different bricks were 31.2, 30.9, 30.5, 30.4 and 30.1℃, with average heat flux values below 0 W/m2. Compared to the no-shadow experiment, both the surface temperatures and heat flux were markedly reduced. Based on the color depth of permeable bricks and combined with shadow layout, reasonable design can help improve the microclimate in arid and semi-arid regions.
