在回顾现代大地测量和我国大地测量工作历史的基础上,对90年代我国大地测量任务,其中包括国家二期一等水准复测;国家GPS网布设;重力场参数精化;GPS卫星追踪站建立;沿海地区陆海相对垂直位移研究和青藏地区壳形变监测等理论和实践工作,作了论述。

The development of modern geodesy and the history of geodetic work in china are reviewed. The future tasks,both in theoretical research and practical work,for Chinese geodesists in 90' s are proposed and discussed: The relevelling of second term nationwide 1st order levelling network;to set up nationwide GPS network;The improvement of the resolution and accuracy of gravity field;The establishment of a GPS satellite tracking network;The measurement for the relative vertical displacement of land versus sea surface in the coast zone;The monitoring for the crust deformation Qing-zang plateau.
