| 摘 要： | 利用密合法求解青藏地区大地水准面模型，研究青藏地区大地水准面主要特征及其与该区内部构造和活动的相关性．表明青藏地区大地水准而异常与青藏高原隆起的形状极为相似，大地水准面整体负异常与下地幔相关，形状起伏与上地幔相对应，岩石层反映的大地水准而异常与青藏高原活动构造有较好的对应关系．

| Abstract: | The high-degree（e．g．360）geopotential model for studying features of local geoid undulation has been obtained，in a“tailored”sense，with mean gravity anomalies in Qinghai-Tibet（Xizang）area．The geoid undulation are closely related to the Earth's internal structure. The negative geoidal undulation come from lower mantle, the undulation shape are attributed to the contribution of upper mantle，and the residual geoid which deducted topographic-isostatic effects and contribution of mantle is corresponding to active structure in this area．The geoid upwarp is similar to uplift in Tibet plateau. |
