摘　　要：地质条件的复杂性决定了地质剖面图完全自动连接的准确性较低。提出一种基于空间语义关系的空区域搜索算法,通过人机交互方式将专家知识应用于剖面连接过程,实现了融合人工编辑的剖面自动化连接方法。该算法通过读入交互结果获得专家知识,在此基础上对剖面地层进行自动化连接。通过语义分解的策略,可以针对实际情况任意组合需要的连接命令。Comparing to drawing section chart with CAD, section chart system provides more professional method which is very useful to make the operation more easy and the chart more exact and integrated. The strata auto--connection improves further the capability of section chart system. But the strata are so complicated that it is hard to get a very reasonable result only through the auto--connection algorithm itself. To use the experts＇ knowledge during the strata connection process, using the human--computer interaction mode,a connection--empty zone hunting algorithm based on the spatial semantics was realized, which allowed the expert to edit the mid--result of the auto--connection algorithm in any step of that. The algorithm connects automatically the section based on the editing results of the export. Through the semantics decomposition users can specify the combination of the connection--orders for different sedimentary facies.
