At first, this paper debates deformation reference system and its establishing method and discusses the integration problem of deformation data in different deformation reference system. Then a block reference system of southeast lithosphere block of EURA plate is established. In the end this paper calculates current relative movement of Chinese land and neighbor plates and analyses current relative movement characteristic of Chinese land and neighbor plates in the block reference system.

本文首先讨论了变形参考系及其实现方法 ,然后讨论了不同变形参考系中变形的数据统一问题。在此基础上 ,建立了欧亚板块东南部块体的块体变形参考系 ,并在该块体变形参考系中联合了 ITRF97速度场和中国 GPS-A级网复测资料计算了中国大陆与周围板块的现今相对运动 ,进而分析了中国大陆及周围板块的现今相对运动规律。

When researching the movement of lithosphere block using repeatedly observed geometric geodesy data, people usually select a stable point or earth fixed reference system as the reference system of movement, and calculate the movement of the researched block relative to the stable point or in the earth fixed reference system. But the calculated results could not directly give the relative movement within the researched block and the movement of round block relative to the researched block. First time, this...

When researching the movement of lithosphere block using repeatedly observed geometric geodesy data, people usually select a stable point or earth fixed reference system as the reference system of movement, and calculate the movement of the researched block relative to the stable point or in the earth fixed reference system. But the calculated results could not directly give the relative movement within the researched block and the movement of round block relative to the researched block. First time, this paper directly selects the researched block, southeastern lithosphere block of EURA plate, as the reference block and calculates linear movement model of southeastern lithosphere block of EURA plate using a precise geometric geodesy data, ITRF velocity field, in ITRF reference system. And then establishes block reference system of southeastern lithosphere block of EURA plate. In the block reference system, this paper calculates 3 dimension current relative movement of neighbor plates relative to southeastern lithosphere block of EURA plate. And then analyses current relative movement law of neighbor plates relative to Chinese continent and lithosphere movement law on borders of plates.

利用几何大地测量监测数据考察某一岩石圈板块或块体的运动 ,目前的主要方法是选择某一相对稳定点或直接选择地固参考系作为运动参考系 ,计算被考察的板块或块体相对于该相对稳定点的运动或在地固参考系中的运动。显然 ,这种计算结果无法全面直观地表达被考察板块或块体的内部相对运动 ,以及周围板块或块体相对于被考察板块或块体的运动。文中首次尝试了直接选择被考察板块或块体即欧亚板块东南部块体作为参考块体 ,利用一种高精度的几何大地测量监测数据 ,即国际地球参考框架 (ITRF)速度场计算了欧亚板块东南部块体在ITRF参考系中的线性运动模型 ,从而建立了欧亚板块东南部块体的块体参考系 ,并在该块体参考系中计算欧亚板块东南部块体内部及周围板块现今三维相对运动 ,进而分析中国大陆及周围板块的现今相对运动规律 ,以及板块边界处板块的现今相对运动规律。
