扎兰屯土壤水分自动站与人工对比分析

Comparative Analysis of Moisture between Automatic Station and Artificial Observation in Zhalantun

以扎兰屯作物地段DZN3型土壤水分自动站与人工烘干称重法对比数据为基础,对数据进行折线图对比分析、误差及标准差分析、相关性分析。从多个维度分析数据,寻找误差组成及来源,制作自动站数据订正模式,使土壤水分自动站能更好地代替人工测量,解决人工取土连续性、时效性差等问题。

Based on the comparative data of DZN3 moisture automatic station and oven dry method of Zalantun crops area,the data were analyzed with the methods of line graph comparative analysis,error and standard deviation analysis and correlation analysis.Analyzing data from multiple dimensions,the composition and source of error were found,the modification model of automatic station was made in order to make moisture automatic station better replace oven dry method to solve the ineffective continuity and timeliness of manual earth collecting.
