摘要
首先对不同历史时期的大地构造学派观点、代表性学术思想,进行了客观、辩证地秉公评说。以地球系统科学为指导思想,在对大地构造学发展史和地球科学现状总结、分析和研究的基础上,提出了统一构造理论的新观点和理论基础,初步建立了理论体系框架。提出了统一引力场表示理论,用Newton位算子将地球内、外扰动引力场统一。通过对地球不同圈层水平速度矢量场的对比分析。提出不同圈层的水平运动速度矢量场具有高度的相似性和统一性,且与地球自转密切相关的认识。根据观测数据,探讨了板块的统一动力源。以中国为例,研究了幔柱构造特征,提出了地幔热柱构造的动力学模型。利用积分关系法求出了地表热流与岩石圈厚度的关系,提出了大陆岩石圈的统一热模式和大陆地表热流经验关系式。以青藏高原为例,研究了大地构造特征和地质过程,提出了隆升的统一构造理论模型。
In this paper,we first objectively analyze viewpoints of geotectonic schools and representive ideas of diffierent stages. Secondly, under the guideline of earth system science, we put forward a theory of universal tectonics,initially build the theoreticl system based on studying the history of geotectonics and present level of earth science.Then we propose the universal grevitation field represention theory,in which the inner and out disturbing field are united by use of the Newton operator. By comparing horizontal velocity of different sphere of the earth, we reach the conclusion that the horizontal velocity of the planet's different sphere is highly similar, united and closely connected with the rotation speed of the earth. By analyzing observed data, we discuss the dynamic source of plate motion.Finally, taking China as an example, we study the behavior of mantal pillar tectonics in the mantle.Using the integral method, we compute the relation of crustal heat flow and lithosphere thickness, and build experical formula of the relation between universal heat model of continental lithosphere and surfacial heat flow of continents.Taking Tibet plateau as an example, we investigate the behavior of geotectonics and geological process, and put forward universal tectonics theory of unplift.
