摘　　要：通过地表移动盆地的动态发展规律分析矿区地面沉降的时空特征,改进基于版本—增量的时空数据模型,建立了沉降要素表、几何表和属性表,实现矿区地面沉降时空信息的集成表达,并分析该方式的主要优势。其中,特征属性在内容上包括矿区地面沉降的发育特征及其影响因素的变化信息,以辅助沉降时空分析、表达时空语义;鉴于不同属性变化的时间粒度及与几何变化的同步性存在差异,将属性字段分别放置在属性表和几何表中,以满足用户的查询需求,减小数据冗余。最后,通过试验集成管理山东省济北煤矿西北部地面沉降的时空数据,分析研究区地面沉降的动态发展规律,发现了该区沉降与采矿活动的相关性,验证了本文沉降时空数据组织方式的可行性。The spatial and attribute information of mining subsidence varies by the interaction of natural environment and human behavior,its spatial-temporal characteristic were analyzed by virtue of the dynamic regularity of ground moving basins.In order to manage the spatial-temporal data,the feature table,geometry table and attribute table were built by spatial-temporal data model based on version-increment,and the advantage of this data organization were analyzed.The attribute fields which involve both development features and inducing factors of mining subsidence were put in geometry table and attribute table respectively for their difference in time granularity and synchronism with spatial variation.By this mean,the query custom and requirement of users can be satisfied,and the data redundancy can be reduced.Finally,the spatial-temporal data of mining subsidence in the western of Jibei coal mine were integrated.The spatial-temporal regularity analysis of mining subsidence were finished and the correlation between mining subsidence and mining activities were discussed.Then,the data organization mode in this paper is showed to be rational and effectively.
