地质系统的复杂性——地质科学的基本问题(Ⅱ)

Complexity of Geosystem: Basic Issues of Geological Science (Ⅱ)

笔者根据其所提出的“地质作用与时空结构是一切地质现象的本质与核心”的自然哲学理念将地质科学的学科体系划分为地球物质的成分与结构、地质作用、地质学场与地质系统的演化等四大基本领域 ,它与 9个重大基础地质问题以及与其相关的基础理论问题相对应 (表 2 ) .笔者将其已发表的地质科学的复杂性理论“地质作用的临界过程动力学———地质系统在混沌边缘分形生长”应用于研究 9个重大基础地质问题 ,着重对于其中所包含的主要基础理论问题的实质及其理论与研究方法作较深入而简要的剖析 .目的是通过将地质系统的复杂性作为地质科学的基本问题的新视角对古老而常新的地质科学进行再认识 ,将重大基础地质问题的研究提高到非线性科学和复杂性理论的层次 ,并实现地质科学向精确科学的跨越 ,取得突破性进展 .

The natural philosophical conception that 'the geological process and spatio temporal structure are the essence and crux of geological phenomena' proposed by the author can be used to classify the geological science as four major academic disciplines: the composition and structure of the earth materials, the geological process, the geological field and the evolution of the geosystem. These four major academic disciplines correspond to the nine important basic geological issues and associated complex theoretical problems (Table 2). In this paper, the author applies the complex theory of geological science 'the dynamics of the self organized critical process of geological process-the fractal growth of geosystems at the edge of chaos' proposed by the author himself to the research into the nine important basic geological issues, with an emphasis on the relatively deep and brief analysis of the nature, theory and research method of the major basic theoretical problems. The purpose of the paper is to understand the geological sciences, old and renewed frequently, from the new point of view of the complexity of geosystem considered as the basic problem of geological sciences, to raise the study of basic geological problems to the level of the nolinear science and the theory of complexity and to complete the transformation of the geological science into a precise science, with an expectation to make a breakthrough in geological process.
