摘　　要：报告了利用中华人民共和国成立以来 ,国家 3期高精度水准测量资料 ,研究中国大陆近 5 0年来垂直运动的方法与结果。论及了净化数据源与使用复测资料的方案。分析了除按大陆整体推求垂直运动速率外 ,按地块分区推求地壳垂直运动速率 ,地壳、地表垂直运动分离的必要性。提出了与地质构造相结合的数据处理方法和所采用的单点动态垂直基准。对使用多面函数逼近速率面 ,在全国范围的实用性实验作了说明。介绍了研究获得的中国大陆垂直运动的最新成果 ,并就运动的特征和趋势进行了论述。This is a report of the research about the Chinese mainland vertical motion with the help of the methods employed,results obtained in recent fifty years, using the materials of the national high precision leveling in three periods since the establishment of the People's Republic of China.And also the scheme of initial data purification and the use of resurveying materials are applied .Analysing the necessity of acquiring the speed of the crust vertical motion and separating the lithosphere and surface by subdividing the massif except the unitary mainland.The authors put forward the method of data processing combined with mathematical model of geotexture and the dynamic vertical datum of single point. It illustrates practicability of impending velocity surface with multiquadric function in nationwide bound. The paper also introduces the latest scientific research in the Chinese mainland's vertical motion, as well as it's features and tendency.
