摘　　要：国家高精度一、二等水准测量是建设国家垂直基准的重要手段,地壳垂直运动将直接影响观测成果质量。基于陆态网络260个基准站GNSS时间序列产品,张力样条函数插值得到中国大陆地壳垂直运动现状,结合高精度水准测量理论与实践得出分析重点区域,并围绕水准环观测闭合周期对正在开展的国家高精度水准观测方案进行优化设计,并可为后续类似工作开展提供参考。National high-precision first and second order leveling is an important means to construct national vertical datum,and vertical crustal movement will directly affect the quality of observation results.Based on the GNSS time series products of 260 reference stations of Crustal Movement Observation Network of China(CMONOC)GNSS network,we can obtain the present situation of crust vertical motion of continental China by tension spline function interpolation.Combined with the theory and practice of high-precision leveling,the key areas of analysis are obtained,and the national high precision leveling obsevation scheme revolving around the closure period of leveling ring observation is optimized,which can provide reference for subsequent similar work.
