摘　　要：通过分析现行区划方法的不足,提出以裸地温度作为路面温度区划主要指标的分区方法。基于路面温度场对路面结构使用性能的影响,选取裸地温度高温、地温和日较差3种特征值,统计分析270个气象站1971～2003年的气象数据,并利用SURFER软件分别绘制3种特征值的等值线图,从总体上分析全国地温的分布规律,为路面观测站的选址和路面温度区划提供参考。Through analyzing the shortcomings of current division method, this paper proposed a new method of pavement temperature division, which took ground temperature as index. Based on the influences of pavement temperature field to serviceability of pavement structures, this paper chose three eigenvalues of high-temperature, low-temperature and daily temperature range, and analyzed statistically the meteorological data of 270 weather stations from 1971 to 2003. Contour maps of the chosen three eigenvalues were drawn by using the Surfer software. And then, this paper analyzed the ground temperature distribution law which shall offer reference for the location of pavement observation station and pavement temperature division.
