【摘要】 阐述了小波变换及多尺度分析方法的原理，利用二维小波多尺度分析方法对中国布格重力异常进行了分解，并从其中划分出有意义的剩余异常．模型结果证明方法有效．由于本文方法可以将重力异常分解成各种几何尺度意义下的不同成分，这为重力解释和研究地壳的结构提供更多更新的依据．更多还原

【Abstract】 Two-dimensional wavelet transform and the multiscale analysis are applied to decompose the gravity field of China. Numerical tests have shown that the wavelet analysis is a powerful tool for decomposition of the reginal gravity anomalies. Using thetechnique of multiscale analysis, We decompose the Bouguer gravity field of China into multiscale components which give new geological meanings for studying the chineselithosphere.更多还原
