| 摘 要： | 利用四川现有156个国家级气象台站历史沿革数据，统计分析了沿革内容05～11项(台站位置、观测仪器、观测要素、周围障碍物、观测时制、观测时间、守班情况)变动情况。结果表明:从建站到2016年，四川气象台站05～11项变动总次数为42588次，平均每站变动273次，其中观测要素和仪器占变动总数的88%。观测仪器变动主要发生在1953、1960、1980、2003、2013、2015年，各观测仪器变化趋势接近，风速风向仪器变动最为频繁。四川省共有132个台站发生过迁站，迁移总数264次，占站点总数的85%，建站初期迁移台站较多，迁移距离一般较近，而2010年后迁移次数呈上升趋势，距离相对较远。

| Abstract: | Based on historical records of meteorological stations in Sichuan Province, the status of 156 national stations, such as location, observation instruments, observation elements, surrounding obstacles, observation time system, observation time and observation class, are counted. The results showed that, From the station to 2016, the total number of 05 to 11 changes of the Sichuan meteorological station was 42588 times, and the average change of the station was 273 times, including 88 percent of the total variation of the observed elements and instruments. The observation instruments mainly occurred in 1953, 1960, 1980, 2003, 2013 and 2015. The variation trend of observation instruments is close to each other, and the variation of wind speed and wind direction observation instrument is the most frequent. A total of 132 stations were relocated in the province, the number of migration was 264 times, accounting for 85% of the total number of stations. At the beginning of the station, the migration stations were more, the migration distance was generally close, and after 2010, the migration times showed an upward trend, the distance was far away. |
