摘要
通过对靖西县1957～2008年部分气象要素的对比分析，发现从1957年至1998年后观测场周围环境逐年恶化，年平均气温、最高、最低气温上升，平均相对湿度下降，雾日、大风日、日照时数减少，SE主导风向受阻，目测项目的准确性受到影响。
Basing on some parts of meteorological elements of Jingxi County during 1957-2008, the comparative analysis showed that the meteorological observation field environment is worsening year by year during 1957 - 1998, which severely affected the observations of meteorological elements, such as the annual average （the maximum, the minimum） temperatures rising , the average relative humidity decreasing, foggy （windy） days reducing, the number of sunshine hours reducing, SE dominant wind direction blocked, and the accuracy of visual items reducing.
