摘要
为了解中国气候条件对公路施工的影响，依据739个气象站1971年～2000年的数据，以累年年施工热量不利日数、累年年旋工降水不利日数作为划分指标，累年年冰冻指数作为辅助指标，采用普通克里金方法对各指标进行空间化分析，进而利用单指标聚类分析、指标划分和图层叠置方法，进行了分区方案研究，拟定了中国公路施工气候影响分区方案，方案共分7个一级区和47个二级区，分区为全面认识影响我国公路施工的气候条件分布和异同性提供了一个平台。
To provide reference for understanding effects of climatic conditions on highway construction, China climatic zoning for highway construction is studied. According to data of 739 weather stations from 1971 to 2000, average annual construction limited days for disadvantageous thermal conditions, average annual construction limited days for precipitation and auxiliary indicator of average annual freezing index are calculated. Spatial distributions of each indicator are analyzed using Kriging method. Then, through methods of cluster analysis, division based on indicator and layers superposing, China climatic zoning for highway construction is given, which includes 7 first level regions and 47 second level regions. The zoning summarizes climate characteristics of impacting highway construction in China.
