针对传统地籍时空数据库管理中基态距与时间相关性较弱及历史检索效率低的问题，本文提出了一种复合型的基态修正时空数据模型。引用动态变粒度基态距因子来优化基态距，并通过改进超图模型空间关系理论来简化时空对象间的空间关系，更好地实现基态的动态更新，提高历史检索效率。
針對傳統地籍時空數據庫管理中基態距與時間相關性較弱及歷史檢索效率低的問題，本文提齣瞭一種複閤型的基態脩正時空數據模型。引用動態變粒度基態距因子來優化基態距，併通過改進超圖模型空間關繫理論來簡化時空對象間的空間關繫，更好地實現基態的動態更新，提高歷史檢索效率。

This article in view of the problem of the weakness between distance of base state and time within tradi -tional cadastral spatio-temporal database management and the low history retrieval efficiency ,puts forward the composite ground state fixed space time data model .Referencing dynamic variable size ground state distance factor to optimize the distance of base state ,and simplify the spatial relationship between time and space objects by improving space relation theory of hypergraph model ,so it will be better to realize dynamic renewal of the ground ,and improve the efficiency of searching the history .
