中国大陆整体无净旋转基准及其应用

通常分析中国大陆水平位移（运动）场所采用的参考基准均是相对于欧亚板块的。这个基准对于分析中国大陆的整体运动及其与欧亚板块运动的关系等是合适的，但在研究中国大陆内部及其周边地区的相对运动时，上述基准就不是很恰当。以“中国地壳运动观测网络”1000余个GPS测站的复测资料（1999～2004）为基础，利用数值逼近理论等方法，给出了中国大陆整体水平运动的旋转参数及其一级块体的旋转参数，并用实际应用算例给予说明。

NO-NET-ROTATION ON CRUSTAL MOVEMENT OF CHINA MAINLAND AND ITS APPLICATION

As analyzing China mainland horizontal displacement (movement) field,the reference is relative to Eurasia plate generally. No doubt it is suitable for analyzing the whole movement of China mainland and its relation to Eurasia plate movement. However, the above reference is not perfect for researching the relative movement of the interior and round region of China mainland.Using the digital aproximetion method and the like,we give the horizontal movement rotation parameters of China mainland and its blocks of first order based on the GPS re-measurement data (1999-2004) of more than 1 000 stations from the Crutsal Motion Observation Network of China (CMONOC).In the end, a practical example is presented.
