| 摘 要： | 本文从地理学的基本研究方法-综合自然区划入手,针对区域地理系统模型的建立过程,通过研究地理空间尺度-空间比例尺以及地理时间尺度-地理事件发生变化的频度,来探讨建立地理事件的时空变化动态表述模式-地理时空等级组织体系,对于体系所提供的地理区域内部地理数据流的组织模式以及体系所表达的区域内发生地理事件过程的动力学作用机制进行了初步探讨,并进一步讨论了该体系对于建立数字地球的作用和意义。

| Abstract: | Based on the basic geographical methodology, comprehensive geographical regionzation and the model construction process of region geographical system, the spatial scale and the occurancl frequency of geographical events were discussed for construcing the hierarchy system of geographical features; which can express dynamically the spatial temperal distribution of geographical events. Firstly we conduct the basic research on the geographical data flux and its organization mode and the mechanic of the geographical event, the the effect of geographical system on constructing the digital earth were discussed in detail |
