| 摘 要： | 本区新构造运动十分活跃,表现出多次波动性,周边山系呈不均衡抬升,盆地则呈不均衡沉降,因此使盆地呈现不对称的簸箕状,盆地中的水系结构也呈现不对称性。区内构造变形主要有褶皱、断裂、新隆起、新坳陷、拱曲和掀斜等,并产生现代地震、地热和火山活动。不均衡掀斜是导致上述现象的根本原因。

| Abstract: | New tectonic movement in this area is extremely active, which showed that the multiple wave movements and the peripheral mountaion system all appeared in the form of the non-uniform lifting and the basin in the form of the non-uniform subsiding.For this reason, the basin emerged in a non-symmetry winnowing fan form. The river system in this basin also is no-symmetrical.The main tectonic deformation in this area is as follows: folds, faults, new bulges, new depressions, arch bends, and tilted fault blocks etc.Nowadays earthquakes, the terrestrial heat and volcanism have been formed.The non-uniform tilting crust-movement is the basic reason for the aforementioned phenomenons. |
