| 摘 要： | 人群的移动模拟应用广泛,但为不同时空尺度模拟需求开发不同的模拟系统十分困难和繁琐。该文设计了一种人群的空间移动模型(GMPM),GMPM具有多粒度特性,可应用于不同的领域,满足不同空间尺度、时间尺度的人群移动模拟需求;同时,GMPM又是一种通用开发模型原型,基于GMPM可以构造针对不同应用领域的人群空间移动模拟模型。最后,介绍了不同时空尺度人群移动模拟应用案例。

| Abstract: | In this paper,the general model for people movements(GMPM) which can simulate different granularity movements for different purposes was discussed.GMPM is a platform,based on which the specialists can develop different application system for terminal users,just by inputting different rules and spatial region definitions.The spatial region can be defined in multi-scales,and rules can be defined for different purpose or from different viewpoints,so GMPM is a multipurpose and multi-granularity model.GMPM consists of four modules:interface,rules and spatial region definition,database,and computation module.The spatial region is represented by a task-oriented model.The rules modeled include 3 types:the basic movement rules,the rules of basic rules changes,and the rules of attributes changes.An event-based database is used to record the movement and attributes changes.The computation module is based on the operations of database.Two case studies are presented,and studies show that the general model is compatible with different application and can simulate people movement over multi-granularity. |
