| 摘 要： | 在中国及邻区大地构造的研究过程中,板块构造理论用于解释中国复杂的大陆动力学过程有所局限,而中国本土的大多数大地构造观点无法展开洋陆对比研究.朱夏和刘光鼎对中国大陆边缘和中国大陆的构造演化历史和动力学体制有其独到的见解,即以活动论为内涵的全球构造理论,我们在此基础上增加了方法论和认识论等内容,提出块体构造学说.块体构造学说在用板块理论解释新全球构造阶段构造现象的基础上,将块体和结合带赋予新的定义和内涵,作为板块之下的二级构造单元,用以表示古全球构造阶段的大地构造单元.本文在简要介绍块体构造学说提出的历史和背景基础上,简述对中国海陆及邻区大地构造演化的理解,系统阐述块体构造学说的大地构造体系,明确块体和结合带的定义、分类和特征,作为正在编制的"中国海陆大地构造格架图"中大地构造单元划分的依据.

| Abstract: | Previous studies on the tectonics of China and adjacent regions suggested that plate tectonics have certain limitations to decipher the complex processes of continental dynamics, and most of the native geotectonic theories in China are unable to make comparative studies between oceans and continents. Tectonic geologists Zhu Xia and Liu Guang-ding, based their studies on the tectonic evolution and the dynamic mechanism of Chinese mainland and continental margins, realized that activism is what we have to insist on for a global tectonic theory. Based on their work, we have recently proposed the theory of block tectonics with some new concepts and methodology. Comparing to the plate tectonics, which focuses on the tectonic phenomena in the new global tectonic stage, we proposed the concepts of blocks and junctures that occur between two blocks, as the secondary tectonic units or the geotectonic unit for the earlier global tectonic stages. In addition to the research background and the basic understanding of tectonic evolution of China mainland and adjacent regions, which were outlined in this paper, the definition, classification and characteristics of the blocks and junctures and their systems are systematically described, which has laid a solid basis for the ongoing map compilation program "Geotectonic framework maps of China land and seas" to make rationale division of tectonic units. |
