华北平原中部草面温度变化特征

Variation Characteristics of the Grass Temperature in the central North China Plain

利用华北平原中部地下水科学与工程试验基地2009～2011年逐日的草面温度、地表温度和气温观测数据,分析讨论了该地区草面温度平均值、极端值、日较差特征以及草面温度与地表温度、气温三者之间的变化关系。

Based on the daily observational temperature data of Grass surface, ground and air from Groundwater Science and Engineering Test Base of Ministry of Land and Resources during 2009-2011, the average temperature, extreme temperature and the diurnal temperature range of the grass temperature were analyzed. The relationships of grass surface temperature, ground temperature and air temperature under various meteorological conditions were also analyzed.
