| 摘 要： | 利用范围约3 000 km2的华南某半山地半丘陵地区的269个重力点实测数据，选取不同的模型类型、建模算法和分辨率等方案分别建模，并比较其模型精度；最后利用3 km分辨率实测数据，采用直接建模的方法建立了该地区的布格重力异常模型，经过外符合精度检验，其精度为1.7 mGal。

| Abstract: | In an approximately 3 000 km2 hilly and semi-mountainous area of South China, 269 gravity points are measured to compare accuracy through various modelling types, algorithms and resolutions. Finally, the Bouguer gravity model anomaly model is calculated by the direct modeling method, and the accuracy was 1.7 mGal after the external coincidence test. |
