【摘要】：地缘环境系统研究是认知国际地缘政治态势、保障国家战略顺利实施的科学支撑。近年来,在国际地缘战略调整、经济全球化和技术进步等要素的驱动下,地缘环境系统研究的内涵与外延都发生了巨大变化。分析地缘环境要素的变化,预估地缘环境演变趋势并提出应对风险的措施,既是地缘环境研究的重要内容,也是实施国家战略的重要科技保障。本文回顾了地缘环境系统研究的学科发展历程及国内外的最新进展,系统梳理了地缘环境系统模拟的理论和方法体系。研究表明,地缘环境系统是一个复杂的非线性系统,具有层次性、地域性、综合性等特征。针对特定的地缘问题,可以采取分层次、合理概化、数值逼近等方法进行系统模拟。同时,大数据技术逐渐成为地缘环境系统研究的新范式,通过异构数据挖掘、机器学习、高性能计算等方法,可望发现纷繁复杂的地缘环境系统中蕴含的要素关联关系,预测与干涉系统演化过程,为地缘环境问题的解决提供新的技术手段。
[Abstract]:The systematic study of geo-environment is the scientific support to recognize the international geopolitical situation and ensure the smooth implementation of national strategy. In recent years, driven by international geo-strategic adjustment, economic globalization and technological progress, the connotation and extension of geo-environmental system research have undergone tremendous changes. It is not only an important content of geo-environment research, but also an important scientific and technological guarantee to analyze the change of geo-environment elements, to estimate the trend of geo-environment evolution and to put forward measures to deal with the risks. This paper reviews the development of geo-environment system and the latest progress at home and abroad, and systematically combs the theory and method system of geo-environment system simulation. It is shown that geo-environmental system is a complex nonlinear system with the characteristics of hierarchy, regionality and comprehensiveness. Aiming at specific geographical problems, systematic simulation can be carried out by hierarchical, reasonable generalization, numerical approximation and so on. At the same time, big data technology has gradually become a new paradigm in the study of geo-environment systems. Through heterogeneous data mining, machine learning, high-performance computing and other methods, it is expected to discover the relationship between the elements contained in complex geo-environment systems. Prediction and interference in the evolution of the system provide a new technical means for the solution of geo-environmental problems.
