摘　　要：从2006年3月1日开始,嵩县气象局自设了水泥面、草面的温度和最高、最低温度观测项目,通过对探测获得的资料与日常地温场观测资料的统计分析,找出了裸地、水泥地、草地3种不同下垫面之间温度的差异:年均温、年均最高最低温度、年极端最高最低温度,草面均低于水泥面和裸地,而冬季草面平均最高温度和极端最高温度高于水泥面和裸地。The observation items such as the temperature on the concrete ground, the grass temperature, the highest and lowest temperature were carried on since March 1, 2006 in Songxian Weather Station. Based on the statistical analysis of the sounding data and daily ground temperature observed data, we find out the temperature differences among bare land, concrete ground and grass land. The mean annual temperature, mean annual highest and lowest temperature, annual extreme highest and lowest temperature of grass land were lower than concrete ground and bare land; while the mean highest temperature, extreme highest temperature in winter of grass land were higher than concrete ground and bare land.
