We analyses 3 kinds of factors to generate the above-mentioned geophysical characteristics, such as the mantle current movement, the mantle thermal plume and the three plates movement surrounding around the continental margin. The forward and fitting results of gravity anomaly along Daxinganling gravitational gradient belt demonstrate the combination of the Earth material density variation in the crust and upper mantle and the Moho interface fluctuation leading to the gravity anomaly of the belt. The stress fields crossed at the continental margin in the East Asia and formed a series along the geophysical characteristics of the gravitational gradient zone. At last, we study the origin of the gravitational gradient zone along Daxinganling Mountain-Taihang Mountain-Wuling Mountain, and present the triple-junction model with dynamic force of compression stress and the upwelling action. %K Daxinganling Mountain-Taihang Mountain-Wuling Mountain %K Gravitational gradient zone %K Continental margin zone in the East Asia %K Plate motion %K Triple-junction model
