摘　　要：以内蒙古气化采煤某试验场测氡数据为例,研究煤气化过程中土壤氡变化规律,反映煤气化燃烧状态。对土壤氡数据进行趋势面分析,以不同拟合次数建立氡趋势面方程,确定最佳趋势面,以氡剩余值圈定土壤氡异常。验证了该方法圈定的氡异常变化与气化进程燃烧区变化相一致。Exemplified by the radon data obtained in the area of underground coal gasification in Inner Mongolia, it researches the variation of soil radon on coal gasification process, reflected the coal gasification combustion state. Used the tendency analysis to analyze the radon data, it establishes radon trend surface fitting equations with different fitting numbers to determine the best tendency, calculated radon residual value and delineated soil radon anomaly. Has validated that the anomalies is consistent with the combustion zone.

关 键 词：趋势面分析 土壤氡异常 剩余值 异常范围
