Except for Tibetan Plateau and its surrounding regions, the results derived from lithospheric isostasy model are closer to observed elevations and consistent with vertical velocities of crustal movement in most tectonic units.

通过对均衡状态分析，我们得到以下主要结论：(1)构造稳定地区均衡程度较高；(2)青藏高原及周边造山带现今地壳运动主要为区域构造过程及深部动力学过程所控制，均衡调整过程不是主要控制因素；(3)现今地壳垂直运动比较明显的块体处于均衡调整阶段，地表垂直运动的大小反映了该区所受的均衡力作用的程度；(4)构造稳定地区基于岩石层均衡的理论计算海拔与观测海拔之差值和现今地壳垂直运动速率有较好的相关性，据此我们可以通过均衡分析研究构造块体的运动趋势和动力学性质；(5)地慢热结构对现今地形、海拔及地壳垂直运动有显著影响，在处理均衡问题时，地慢岩石圈热结构是我们必须考虑的重要因素。
