摘　　要：行为特征是多粒度时空对象的重要特征,是对象之间控制与响应的重要方面,是体现时空对象相互作用、动态变化的核心。传统GIS往往采用系统外挂的方式解决对象的响应与控制问题,无法提供底层模型支持。针对这一问题,采用多粒度时空对象数据模型为对象行为建模,描述对象行为特征的框架,设计其逻辑数据结构和存储格式,在此基础上,研究行为的触发和调用机制,设计其在全空间信息系统中的运行流程,最后搭建原型系统进行实验。结果表明,设计的模型框架、触发和调用机制可以从模型底层有效解决对象的控制与响应问题,具有一定的实用性和可靠性,能够为多粒度时空对象的行为表达提供科学依据。As one of the important characteristics of multi-granularity spatiotemporal objects,the behaviors of objects are of great significance to understand the interactions and dynamic changes of the spatiotemporal objects.Research on behaviors of objects helps to control objects and make responses,which usually rely on system plugins and is lack of model supports in traditional GIS.This article proposes a new framework to describe the behavior properties of multi-granularity spatiotemporal objects and designs its logical data structure and storage format.Based on which,we explore the triggering and calling mechanisms of object behaviors,and design the object operation process of the pan-spatial information system.Finally a prototype system is developed.Experimental results show that the model framework and triggering and calling mechanisms of objects designed in this article help effectively solve the object control and response problems of underlying models The model framework of object behaviors is practical and reliable,and provides scientific supports to the behavioral expressions of multi-granularity spatiotemporal objects.
