摘　　要：为了解决“辽金古城”遗址个性化的空间数据表达与管理问题,该文基于面向对象和空间数据库思想,在古城空间结构和拓扑关系分析的基础上,从空间特征、图形表达、属性结构和数据集组织层次等4个方面构建古城空间模型;然后,根据数据查询、修改和分析现实需求,设计相应的数据管理、数据查询、操纵和分析方案并采用ArcGIS Geodatabase空间数据库,以“C#+OLEDB+ArcEngine”编程模式,解决整体与个体古城空间数据间的联动管理问题,验证古城空间数据模型实例化和数据管理关键技术。研究结果表明,古城空间模型构建的关键是利用线图形、面图形反映古城主体框架和主体结构,点图形表示古城重点要素。图形间的空间拓扑要严谨,以反映地物之间的关系,每个要素类单独设计属性结构反映其主要文化内涵和空间信息,采用数据库封装方式管理古城要素;基于该文提出的空间数据模型将古城视作独立对象进行实例化,通过程序对文件、数据库、SQL语言进行融合式算法设计,可实现个体、总体古城数据交互式查询和管理,并可利用GIS软件平台和二次开发技术解决古城空间数据空间显示与分析问题。该研究为古城空间数据建模与管理提供一种可行的方法,对其他有个性化空间信息管理需求的实体建模具有一定的借鉴意义。In order to solve the problem of personalized spatial data expression and management of the site of ancient city of Liao and Jin dynasties,based on the idea of object-oriented and spatial database,and on the basis of the analysis of the spatial structure and topological relationship of the ancient city,this paper constructs the spatial model of the ancient city from four aspects:spatial characteristics,graphic expression,attribute structure and data set organization level.Then,according to the actual requirements of data query,modification and analysis,the corresponding schemes of data management,data query,manipulation and analysis are designed,and the ArcGIS Geodatabase spatial database is adopted to solve the problem of linkage management between the whole and individual ancient city spatial data with"C#+OLEDB+ArcEngine"programming mode,and the key technologies of instantiation of ancient city spatial data model and data management are verified.The results show that the key to the construction of the spatial model of the ancient city is to use linear and area graphics to reflect the main frame and structure of the ancient city,and point graphics to represent the key elements of the ancient city.The spatial topology between drawings should be rigorous in order to reflect the relationship between features.Each feature class designs its attribute structure separately to reflect its main cultural connotation and spatial information,and database encapsulation is used to manage the elements of the ancient city.Based on the spatial data model proposed in this paper,the ancient city is instantiated as an independent object,and the integrated algorithm design of file,database and SQL language can realize the interactive query and management of individual and overall ancient city data,and the problem of spatial display and analysis of ancient city spatial data can be solved by using GIS software platform and secondary development technology.This study provides a feasible method for the modeling and management of spatial
