摘　　要：多粒度时空对象的行为特征是描述全空间信息系统中不同对象之间控制与响应的重要方面,是体现时空实体相互作用、动态变化、多能自主的核心,是全空间信息系统作为一个"活"的信息系统的亮点所在。本文面向全空间信息系统,对多粒度时空对象行为的基本概念、触发方式、分类方式、描述框架进行了阐述,在此基础上,提出了多粒度时空对象行为特征的总体形式化描述方法,并分别从行为能力、环境影响因素、行为触发条件、行为作用对象和行为计算模型5个方面对对象的行为特征进行详细描述,为全空间场景中多粒度时空对象的行为建模提供了基本思路。Behavior characteristics of spatial-temporal objects of multi-granularity are the important aspects to describe the control and response among different objects in pan-spatial information system,and the highlight of the pan-spatial information system as a living information system.The core of the behavior characteristics embodies in the interaction,dynamic change,and more actions and autonomy of spatial-temporal entity.The aim of this paper describes the pan-spatial information system and the basic concepts,trigger mode,classification methods and the frame of behavior of spatial-temporal objects of multigranularity.On this basis,it puts forward a general formal description method of behavior characteristics,and describes in detail of behavior characteristics from the following five aspects:behavior abilitys,environmental factors,behavior triggering conditions,behavior effect objects and behavior computational models.Finally,it provides the basic idea for the behavior modeling of spatial-temporal objects of multi-granularity in pan-spatial scene.
