介绍了中国地壳运动观测网络的布设、基准站和基本站首期观测情况。利用GAMIT和GLOBK软件对首期观测数据进行了处理，计算结果归算到ITRF97框架上。单天整体解结果表明：基线重复性NS向分量为2.28+0.87×10-9×S，EW向分量为3.67+0.82×10-9×S，高程分量为6.84+1.29×10-9×S(S为GPS站间距离，以mm为单位)。对基准网和基本网的整体平差结果表明：点位精度水平分量为2～3 mm，高程分量为3～5 mm，基准网和基本网首期观测达到了设计要求。

The distribution and the first epoch measurement of the crustal movement obser-vation network in China are described. The GPS observational clata of the fiducial networkand basic network is processed with different package of GAMIT/GLOBK. The computationalresults are obtained with ITRF97 as reference frame. Results show that the repeatability ofbaseline N-S component is 2.28+0.87×10-9×S, the one of E-W component is 3.67+0.82×10-9×S, and the one of vertical component is 6.84+1.29×10-9×S, where S is distancebetween GPS stations with unit of mm. After the integral adjustment of the fiducial networkand basic network, it shows that the horizontal component of coordinate precision of stations is2～3mm, the vertical component is 3～5mm. It can be concluded that the first epoch measure-ments meet the requirements of design.
