利用2008年12月至2009年2月烘干称重法、自动观测的土壤湿度及同期气象资料进行统计分析得出:(1)在同一气候环境、同一地段烘干称重法与自动观测的土壤湿度变化趋势是一致的,0～10cm土壤湿度一致性最好。(2)烘干称重法测得数据所反映土壤湿度的变化程度大于自动观测。⑶烘干称重法、自动观测的0～50cm土壤湿度与降水、气温相关密切,建立的回归方程通过0.01的显著性检验,采用烘干称重法测得的土壤湿度与气温、降水的响应程度好于自动观测。
Using the drying weighing method from December 2008 to February 2009, automatic observation of soil moisture and synoptic meteorological data for statistical analysis: (1) in the same climate, the same area drying weighing method and automatic observation of Soil moisture trends are consistent, 0 ~ 10cm soil moisture consistency is best. (2) The data measured by the drying and weighing method reflect the degree of change of soil moisture more than the automatic observation. ⑶ drying weighing method, automatic observation of 0 ~ 50cm soil moisture and precipitation, temperature is closely related to the establishment of the regression equation by 0.01 significant test, measured by the drying method of soil moisture and temperature, precipitation response Degree better than automatic observation.
