摘　　要：本文采用算法重建的方式对山西省级自动站实时气温数据质量控制结果进行再分析，旨在总结分析气温判定可疑和错误的具体因子，寻找优化系统参数，提高系统自动判定准确率的方法。本文从气候学界限值检查、区域界限值、站点界限值、内部一致性和时间一致性等气温质量控制方法出发，对系统判定的2011年6月、7月、8月气温、最高气温和最低气温为可疑和错误的值进行再分析。由于空间一致性检查比较复杂，本文不包含空间一致性算法重建，从6月、7月、8月再分析结果来看，山西省气温判定结果中时间一致性判定的小时变率判定量最大。The re-analysis of real-time temperature data from automatic weather station in Shanxi Province was done based on the reconstruction algorithms. Its aims were to summarize and analyze temperature and determinate the error factor and look to optimize system parameters and improve the accuracy of automatic determining. The temperature quality control methods of the climatic limit check, the area threshold value, value of the site boundaries internal consistency and temporal coherence were used and the suspicious and error value of the temperature, maximum temperature and minimum temperature in June, July and August 2011 were re-analyzed.
