中文摘要： 时空数据模型是时态地理信息系统的核心研究范畴。主流时空数据模型主要面向数据库高效存储与检索的数据结构化组织与管理研究，缺乏融入模型中内在的时变机理描述与表达，而这种机理响应着时变，是探寻时变规律的基础。本课题以地学时变机理研究为切入点，开展地学时变机理在时空构模过程中的健壮性描述、表达与整合研究。基于地理本体思想，提出多类型、多语义、多因子与多规则的地学时变机理描述与表达新框架；借助面向对象技术，构建地学时变机理模型与时空模型的集成新模式。本课题的研究具有丰富的理论意义与重要的应用价值。通过本课题研究，有望解决传统地理信息系统理论与方法中有机集成地学时变机理与时空模型的瓶颈问题；通过地学时变机理健壮性描述与表达的探索性研究，有助深化、完善地学时变机理及地学时变规律的认识，有助提升和丰富时态地理信息系统的时空建模理论框架；进而可为海量数据加工与处理过程中的自动化、智能化和实时化提供理论支撑。

英文摘要： Spatiotemporal data model (STDM) is the core category study of the time geographic information systems (TGIS). The mainstream of STDMs are based on the research of effective storage and retrievals of the structural space-time data, but lack of the integration of geo-time-variation machisims(GTVM) with minging the time-varying regularity into the STDM. As a breakthrough point of the GTVM, the study will make researches on the robustly descripted, expressed GTVM and integratied into the STDM. Based on the geo-ontology thought, this study put forward a new framework with the description and expression of 'mlti-types, multi-semantic, multi-factors and multi-rules'. By virtue of Object-oriented technology, it offers a new integrated mode with GTVM and STDM.This study might have an important significance in the theoretical and applied value. Through deeply research, it is expected to solve the bottleneck problem of the organic integration with GTVM and STDM in the traditional theories and methods of GIS; Through the exploration of the robust GTVM, it is helpful for deepenly understand the mechanism of time-varying regularity,for enhancing and richening the spatialtemporal modeling framework in TGIS. And then, it can provide the theorectical supports for the automatization, intellectualization and real-time transform
