| 中文摘要:利用气候界限值（要素允许值）检查、台站气候极值检查、时间一致性检查、内部一致性检查、空间一致性检查，对自动土壤水分站的实时资料进行了自动质量控制。针对各层水分间没有具体的大小关系和等式关系，提出一种通过比较各层水分一小时变化值大小来判别数据质量的内部一致性方法。应用上述质量控制方法，对安徽省2011年4月-2011年7月共4个月近82个自动土壤水分站的8层土壤体积含水量数据进行了质量控制，错误检出率为1.49%。经自动质量控制后，实时水分数据的可靠性有较大程度提高。试验表明，安徽省82站1个时次的体积含水量数据可以在3min内完成质量控制，能保证实时业务运行时效。 |

| The Method of Automatic Quality Control for Real-time Data from Automatic Soil-moisture Station |

| Abstract:The automatic real-time quality control for automatic soil-moisture stations is made by using climatic extreme range check (or element allow value check), climatic extreme range of stations check, time consistency check, internal consistency check and spatial consistency check. Against the condition that there are no size and equation relationships between each layer of soil volumetric water content, an internal consistency method is developed by comparing the one-hour change of volumetric water content in each layer. Using the methods above, 8-layer data from 82 automatic soil-moisture stations from April to July in Anhui Province were checked and the checked rate of error is 1.49%. The experiment result shows that the data quality has been greatly improved and the quality control process for an hour data from 82 stations can be completed within 3 minutes. |
