利用中国陆地 10条GGT地球物理资料编制中国岩石圈篱笆图 ,并加以说明。通过对地球物理特征和地质学分析 ,认为以大兴安岭—太行山—武陵山重力梯级带和青藏高原周边重力梯级带为界 ,可把中国陆地划分 3个岩石圈构造单元。中国陆壳既有三分结构也存在二分结构 ;对地壳中存在的低速带、高导带和天然地震带进行了划分。以大兴安岭—太行山—武陵山重力梯级带为界 ,两侧盆地具有不同的地球物理特征 ,这些特征与构造运动、均衡调整过程有关。莫霍面几乎遍布全国 ,它具有内部结构。下部地壳底部存在的地球物理异常与莫霍面有关 ,也可能与岩石圈地幔的变化有关。
The Chinese lithosphere fence map is compiled using 10 GGT geophysical data on the Chinese mainland and is illustrated. Based on geophysical characteristics and geology analysis, it is considered that three lithospheric tectonic units can be divided into Chinese terrestrial land by taking the gravity cascade zone of Daxing’anling-Taihangshan-Wuling mountain and the gravity gradient zone around the Qinghai-Tibet plateau as a boundary. The continental crust of China has both the dichotomy and the tertiary structure. The low-velocity belt, high-conductivity belt and natural seismic belt existing in the crust are divided. Taking the Daxinganling-Taihangshan-Wuling mountain gravity cascade as a boundary, the basins on both sides have different geophysical characteristics, which are related to the tectonic movement and the equilibrium adjustment process. Moho almost all over the country, it has an internal structure. The geophysical anomalies existing at the bottom of the lower crust are related to the Moho and may also be related to changes in the lithospheric mantle.
