| 摘 要： | 本文从理论上对相关分析法区分重力异常的可行性进行了论述，并从一元线性回归方程着手，对大地水准面上的重力值与相应的地形高程作了相关分析，通过分析，认为在区域性小比例主均衡补偿基本完善的条件下，重力值与高程有极好的线性相关关系；当计算窗口较大时，地下的局部不均匀体，不足以破坏重力值与高程的相头发一，所以，在实际工作中，利用相关分析处理重力资料的叠加场，可以收到较好的效果，且方法简单易行。

| Abstract: | This paper theoretical studies the feasibility of gravity anomaly divided by means of correlation analysis method. It is made that the correlation analysis of gravity value on geoid and its topographic elevation by use of univariate linear regression equation. The results show that there is perfect Linear correlation relation between gravity value and elevation under the conditions of areal small scale and perfect isostatic compensation. When there is bigger compute window,undergroud partial uneven body of density can not destroy the correlation relation between gravity and elevation. It can get a good effect that dealing With the superposed field of gravity data by use of correlation analysis,and the method is easy and feasible. |
