摘　　要：根据最新精细重力异常场及其三维反演结果，用类比法研究了鄂西与滇西两区域各波长重力场变异特征和地壳层间结构差异，并对重点监测区危险地段划分所需的深部构造信息和动力学特征进行了探讨。Based on the results of the latest gravity anomalies and their inversion in 3-dimension,the variant characters of gravity field with all kinds of wave length and the difference of the structure of crustal layers are studied using the method of comparison.The informations of deep structure for dividing the risk parts in the monitoring area and their dynamic characters are also studied in this paper.
