农业气象自动站与人工观测值的对比分析
Comparative Analysis of Values Obtained through Automatic Agricultural Weather Station and Artificial Observation
摘要
Abstract
The relative soil humidity data obtained by DZN1 automatic soil moisture observation instrument and parallel artificial observation from March 3, 2011 to November 13, 2011 in Jiyang County were analyzed by the methods of contrast difference, difference probability, correlation coefficient. The results showed that the artificial observation data reflected greater fluctuation of soil moisture, while that obtained by automatic observation instrument changed in relative gentle. The consistency of artificial and automatic observation data was the best in the 0～10 cm and 10～20 cm of deep soil layer, while that in 70～80 cm of deep soil layer was the worst. The results provided objective basis for evaluating the monitoring capability of DZN1 -type automatic soil moisture observation instrument, thus the soil moisture observation data could be utilized well in economic construction and production of industry and agriculture.关键词
