【摘要】 通过对吐鲁番农业气象试验站2006年3月～11月 HYA-SF 土壤水分自动监测站和土钻法测定的土壤水分资料进行对比和相关分析,结果表明:两种土壤水分在垂直动态分布上较为一致、在时间动态变化上,受5 cm～80 cm 月平均地温的影响;5 cm～50 cm 土壤水分在5 cm～80 cm 月平均地温≥25.0℃时,在不同的水平信度上具有较好的相关性。更多还原

【Abstract】 The observation data of HYA-SF soil moisture auto-monitoring station and Soil Drilling method is contrastively analyzed,the results show:the observation data of two methods display accordantly in vertical dynamic distributing and is affected by monthly mean soil temperature of 5cm -80cm.When the monthly mean soil temperature of 5cm -80cm is above 25℃,two methods have high relativity.更多还原
