摘要
针对时空过程模型是实现地学现象回溯和预测的有效方法,采用基于并行过程和信息传输的时空过程概念模型构建方案,将时间、空间及时空域相结合构建时空过程模型,以过程的概念解释时空过程模型的空间域,引入π–演算并将其语义和语法同过程结合,促进每个域之间的信息传输能力.以陆地龙卷风作为案例进行研究,研究结果表明:时空过程模型的工作原理是正确的,过程具有不同状态及其转换具有可持续性.该研究成果为时空模型研究提供新思路.
The spatio-temporal process model(STPM) is an effective method to resolve the assumption and prediction of geoscience phenomena.In this study,a conceptual model for spatio–temporal processes was developed based on the concepts of concurrent processes and message transmission.The STPM was built by integrating spatial,temporal,and spatio-temporal processes.The spatial nature(domain) of this model was also captured in the concept of a process.In addition,the syntax and semantics of π–Calculus was incorporated with the procession of this model to enhance the potential of messages transmission among domains.A real world case study was conducted to test the model and its sustainability over various situations.The case study shows that the model is valid.
