摘要
GIS与地理学的结合 ,有助于地理学家分析区域性或全球性一系列的地理问题 ,研究大气圈、水圈、岩石圈、生物圈等圈层内部的结构特征、分布规律、演化过程以及彼此之间物质流、能量流、信息流的传递方式及动力学机制。虚拟 GIS的发展 ,地理学家通过所建立的虚拟境界 ,亲自感受和认识复杂的关于地质、地貌、水文、气象、土壤、植被等数据的空间关系和物理关系 ,深化对其内部机理的认识 ,探索数值模拟及定量化研究的方法及途径 。
The integration of GIS and geography helps geographers to analyse a series of regional or global geographical problems, to study the inner structural feature, distribution patterns, evolution process among atmosphere, hydrosphere, lithosphere and biosphere, to research the ways and mechanism of material flow, energy flow and information flow. Earth system is a large system that has many factors and complex structure. Moreover, the system is changeable with the variety of natural function and human activities. The researches of earth system and its related problems depend on new technologies. Geographers can understand space and physical relationship of data on geology, geomorphology, hydrology, meteorology, pedology and botany with the development of VRGIS. Meanwhile, geographers can know the inner mechanism of geographical environment, seek the ways of digital modular and quantitative study, and push development of digital earth theory and quantitative geography research.
