| 摘 要： | 分析认为时空过程语义兼具连续体和偶发体的双重特性,是对现实世界地理过程的简化与抽象表达。针对对象建模视图和基于事件模型不足以描述过程语义的缺陷,提出了一种显式建模地理过程的HAS表达框架,将过程视图剖分为发生(Happenings)、动作(Actions)与状态(States)三域,分别描述时空过程的起因、行为过程和结果状态。在土地利用管理系统中的应用表明,其能较好地对土地利用变迁过程进行表达,能够通过时空查询实现对土地利用变迁过程的整体复原。 |

| Abstract: | Modeling geographic process is the key foundation for analyzing geographic spatio-temporal phenomenon and abstracting spatio-temporal high-level knowledge.Semantics of spatio-temporal process are analyzed,which are simplified and abstract representation of real world geographic process and have both characteristics of continuants and occurrents.To solve deficiencies of process semantics representation based on object modeling view and event model,an explicit representation framework of geographic process named HAS is proposed in this paper,which divides process view into 3-domains of Happenings-Actions-States to describe causes,behavioral processes and result states of process respectively.The concept of process and 3-domains definition of process are discussed,and the decomposition expressions of process/event based on temporal topology constraint,spatial topology constraint,referencial constraint and conditional constraint are proposed.Besides,the modeling case,database schema and system implementation of land use change process are presented,which show that HAS is good for representation of land use change processes,and the land use management system based on HAS can recover whole land use change process by spatio-temporal queries. |
