摘    要:对莒县气象局2005年9月21日至2006年12月18日期间非灌溉自然状态下农业气象自动站与同地段人工平行对比观测的土壤相对湿度资料,采用对比差值、差值概率和二者相关系数等方法进行统计和分析.结果显示:0~5 cm和0~10 cm的自动站采集的数值不理想;10~20 cm、40~50 cm效果较好.结论认为:0~10 cm传感器参数需作调整;需更换传感器,其设计须考虑冻土的影响;90~100 cm深度的数据变化平稳,可以考虑不安装90~100、170~180 cm层次的传感器.

关 键 词:农业气象自动站  土壤相对湿度  对比分析

Abstract:The soil relative humidity measurements from the agrometeorological automatic station and manual observation of the Juxian Meteorological Bureau at the same time in a natural state of non irrigation from 21 September 2005 to 18 December 2006 are compared and analyzed by means of the difference contrast, difference probability, and correlation methods. The results show that the measurements from the automatic station are unsatisfactory in the layers of 0-5 cm and 0-10 cm but satisfactory in the layers of 10-20 cm and 40-50 cm. It is concluded that the 0-10 cm sensor parameter must be adjusted and replaced, and the design of the sensor must consider the influence of frozen earth. The variation of 90-100 cm depth data is steady, so it is suggested to cancel the sensors at the two levels of 90-100 cm and 170-180 cm.
Keywords:agrometeorological automatic station  soil relative humidity  comparative analysis
