摘　　要：针对似大地水准面精化和利用GNSS大地高获取点位的正常高在进行水准拟合这两种获得点位高程的问题,采用Bland-Altman一致性算法,进行两种测量结果的差值、比值和百分比值三种方法进行作图分析,计算它们的一致性界限和一致性界限范围内的比例,并做出一致性推断。通过河南省某地的实例分析,提出的Bland-Altman一致性算法能较好地解决两种测量方法的一致性问题,研究结果表明通过Bland-Altman的一致性界限分析,可以解决似大地水准面精化和GNSS水准拟合高程是否具有一致性的问题。提出的采用Bland-Altman算法进行两种测量方法的一致性算法,实现了两种测量方法的是否具有一致性的定量分析。According of two methods of the refined Quasi-Geoid and leveling fitting,normal height using GNSS geodetic is used.In this paper the Bland-Altman consisitency algorithm is analyzed difference value,ratio and percentage of two meausing methods and drew graphics according to obtain the measurement results.The consistency boundaries and consisitency ratio within the scope of the consistency of boundary are calculated and make the consistency inferences.Through a example of a certain place in Henan province,proposed the Bland-Altman consisitency algorithm can solve the problem of the consisitency of the two methods of measurement.The results show that through the analysis of the Bland-Altman consistency scope,their consistency of the refined Quasi-Geoid and GNSS level fitting is solved.The Bland-Altman algorithm is proposed to the consistency algorithm of two measuring methods,and consistent quantitative analysis of the two measuring methods is realized.
