自动土壤水分数据质量控制中的阈值确定

摘要

Based on mathematical statistics, application value of soil moisture data were improved. The distribution and extreme situation of soil moisture data in each year observed by manual in different depth were analyzed. Threshold value of each depth was determined, which could be used for monitoring soil moisture. It can also provide references for automatic quality monitoring and abnormal data analysis of soil moisture in the whole province.%为了提高自动土壤水分资料的应用价值,采用数理统计学方法,分析不同深度人工观测土壤水分资料的历年分布和极值状况,研究确定各层土壤水分资料的阈值并应用于自动土壤水分监控,为实现全省土壤水分质量自动化监控和数据异常分析提供重要参数。
