【摘要】 地理信息系统与遥感技术的发展,为进行区域地理特征的时空分析提供了技术手段和信息源。论文首先在现有时空数据模型的基础上,提出了利用面向对象技术建立模型的方法,并基于改进的基态修正模型建立了三峡库区地理时空数据库。其次,基于地理时空数据库,利用土地利用动态度模型、土地利用类型相对变化率、重心迁移模型和多元线性回归方法分析了巫山县19个乡镇居民用地的时空变化及其驱动因子。最后,基于ArcObject,利用Visual Basic6. 0开发了三峡库区基础地理空间数据管理系统,实现了基本的GIS功能,并可有效的对地理时空数据进行管理。

【Abstract】 The development of Geographical Information System and Remote Sensing has provided technical means and information source for spatial-temporal analysis of conducting regional geographical features.Firstly, on the base of the current spatial-temporal data model, a method of establishing model with Object- Oriented technique is proposed. Based on the revised spatial-temporal data model of bade state with amendments, we built geographic spatial-temporal database of SanXia reservoir.Secondly, based on geographic spatial-temporal database, using land use dynamical change models, land use type relative change models, barycenter model and multiple liner regression, the spatial-temporal changes of WuShan country’s resident land use and drive factors are analyzed.Lastly, We Using Visual Basic 6.0, SanXia reservoir fundamental geographical information management system is built based on ArcObject components. The system realizes the basic operation in GIS. Furthermore, the systems satisfy the requirement of the fundamental geographical information management.
