摘　　要：东海陆架盆地和冲绳海槽盆地在区域地质构造上虽然同属下沉区，但它们的重力异常（其中包括布格异常、空间异常和均衡异常）、地貌特征、沉积环境、地壳类型、应力分布、构造活动、成因机制上均存在着本质的差别，从而揭示了两者决不是简单的“块体”下沉，而是两个性质完全不相同的构造单元。Although both the East China Sea Shelf Basin and the Okinawa Trough Basin belong to sinking areas in regional geological tectonics, differences in nature exist in their gravity anomalies (including Bouguer gravity anomaly, free air gravity anomaly and isostatic gravity anomaly), morphologic properties, sedimental environment, crustal types, stress distribution, tectonic activities and formation mechanism, thus revealing indicate that they are not simple 'Block' sinking, but belong to two tectonic units completely differences in nature.
