摘　　要：为了满足对地学现象历史回溯和动态反演的需要,必须从过程的角度来解释现实世界的现象。本文提出了一种时空过程模型,该模型从过程的角度来定义和表达地学现象,描述了地学现象演变过程中一个信息如何随着时空的推移而发展,给出了时空过程模型的时空过程语义描述,并以海上龙卷风为例,建立了时空过程模型。To meet the requirements of geoscientific phenomena historical flash back and dynamic inversion, the real world must be recognized in a process aspect. A new spatio-temporal process model was presented in this paper to define and describe geoscientific phenomena in a process perspective. It described the progress that a signal changes with the time and space changing in the evolution process of geoscientific phenomena. The semantic description of the spatio-temporal process model was given then, and finally an exam- pie of waterspout was taken as a case study to make the model.
