摘　　要：为了能够准确监测西南地区电离层TEC变化规律,采用VBA编程创建宏的方法在Excel中提取GPS观测值,运用Matlab计算得到了西南地区TEC变化曲线,并对西南地区TEC变化规律进行分析。结果表明:北京时间12点至19点之间,西南地区电离层TEC值较高,峰值出现在14点至16点之间,并且变化比较活跃;在23点至7点之间,电离层TEC值较低,并且变化相对平稳;春秋两季TEC峰值要高于夏冬两季。In order to be able to accurately monitor variation law of the ionosphere TEC in southwest of China, we adopt the method of VBA programming to create macros in Excel to extract GPS observations, using Maflab to calculate the curves of TEC in southwest of China, and analyzed the variation law of TEC in southwest of China.Results showed that the Beijing time between 12 to 19, the value of the ionosphere TEC of southwest area is higher, the peak appeared in between 14 to 16, and the change is active;but between 23 to 7, the value of the ionosphere TEC is lower, and the change is relatively stable. During spring and autumn the peak of TEC is higher than that in summer and winter.
