【摘要】：本文对东莞南社村村落民居室外的树荫、池塘、瓷砖铺地与砖铺地4种下垫面的垂直温度梯度进行连续采集,分析了不同下垫面的温度梯度分布的变化规律与差异。研究表明:太阳辐射是影响空气温度的重要因素;不同下垫面上方的温度在0.5 m以下发生明显的波动,且气温近似在0.5 m处达到最大值;冷巷可以有效地降低下垫面的表面温度,表面温度可比气温低5.3℃。测试结果为进一步研究岭南民居微气候及社会主义新农村建设提供实验依据。
[Abstract]:In this paper, the vertical temperature gradients of four kinds of underlying surfaces, such as tree shade, pond, ceramic tile floor and brick floor, are continuously collected, and the variation law and difference of temperature gradient distribution of different underlying surfaces are analyzed. The results show that solar radiation is an important factor affecting air temperature, the temperature above different underlying surfaces fluctuates obviously below 0.5 m, and the temperature reaches the maximum value at approximately 0.5 m. Cold roadway can effectively reduce the surface temperature of the underlying surface, and the surface temperature is 5.3 鈩，
