不同下垫面温度分布的对比观测与分析

摘要

Outdoor vertical temperature gradient of four different kinds of underlying surfaces including shade of trees、pond、Ceramic tile floor and brick floor located in a residence,NanShe village,DongGuan city is collected continuously in this paper,and the variation and differences of vertical temperature distribution of the four different kinds of underlying surfaces is analyzed.The result shows that:Solar-radiation is an important factor affecting air temperature;The air temperature above the four different kinds of underlying surfaces fluctuates significantly under the elevation height of 0.5 m and reaches the maximum value approximately at the elevation height of 0.5 m;Cold lane can effectively reduce the surface temperature of the underlying surface,the surface temperature is 5.3 ℃ lower than the air temperature.This can provide experimental basis for further micro-climate research of south China residence and new socialist countryside construction.%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0.5m以下发生明显的波动,且气温近似在0.5m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.
