摘要
研究方法论的变革是推动地理科学发展的动力。 90年代以来 ,作为地理科学方法论之一的数量地理学迅速向全新的地理计算学发展。凭借高性能计算软、硬件设备的支撑 ,一些以“整体性”、“大容量”资料所表征的地理学时、空演变问题的模拟、预测 ,逐渐得以实现。以国内外文献资料为基础 ,追溯了国外地理计算学的发展 ,讨论了地理计算的内涵和构成 ,分析了作为地理计算基础的高性能计算的基本特征 ,介绍了在几个地理学固有命题 (空间互作用、人口、城市演变动力学 )研究中凭借高性能计算所进行的成功探索 ,旨在为启动我国的地理计算学研究 。
The progress and change in research methodology are the driving force of putting geographical science forward. Since the 1990s, as a branch of geographical methodologies, the theoretical and quantitative geography has been progressed in a whole newly branch Geocomputation. By using a lot of hardware and software necessary for high performance computing, it is possible to model and predict the evolution of some spatial temperal problems in geography. Taking a lot of foreign and native literatures as a base, this paper traces the progress and development of geocomputation in geographical circle in the world, discusses the composition and connotation of geocomputation, analyses the basic characters of high performance computing, and introduces some successfully exploration and application of high performance computing in a few inherent propositions in geographical researches including spatial interaction, population and urban evolutionary dynamics. The aim of the paper is to offer some profitable references for starting geocomputational researches in China.
