摘　　要：基于自然保护区数据特点,通过统一数据标准、拓扑检查及修正、GIS数据库逻辑模型设计、地图符号设计与测试等主要技术方法对自然保护区地理空间数据整理建库并可视化。整合了多源异构地理空间数据,研究了矢量地图符号设计的理论与方法,设计了地图符号可视化测试工艺,并在此基础上完成了地图模板的制作。在辽宁蛇岛老铁山国家级自然保护区选取保护区范围及功能区划、珍稀鸟类分布两个专题进行了实例验证,结果表明:提出的关键技术能够为自然保护区数据空间可视化和科学利用提供支持,并且地图数据分析结果为自然保护区精细化管理提供了参考。In order to fully utilize spatial data of natural reserve,this paper proposed natural reserve thematic mapping key technology.Based on the characteristics of the nature reserve data,the main technical methods such as unified data standards,topology inspection and correction,GIS database logical model design,map symbol design and testing,etc.are used to organize and visualize the geospatial data of the nature reserve.Multi-source heterogeneous geospatial data is integrated;the theory and method of vector map symbol design is studied;map symbol visualization test technology and manufactured map template are designed;on this basis,the production of map template is completed.In the Laotie Mountain National Nature Reserve of Snake Island,Liaoning Province,two thematic examples of the scope and functional zoning of the protected areas and the distribution of rare birds were selected for verification.The results show that the key technology proposed by this paper can help natural reserve in data spatial visualization and scientific utilization.And the map analysis results can be the reference for natural reserve fine management.
