摘  要:为提高林业调查规划专题图编制的工作效率,讨论了基于拓扑约束理论的数字专题图制作方法和原则,利用点位的拓扑关系建立小班地域的邻接矩阵,和小班属性矩阵作为自动聚类的基础矩阵,并通过MapBasic编制程序对MapInfo进行二次开发,结合Excel等软件,实现了小班多边形自动聚合及分类,为林业专题地理信息系统研究奠定基础。小班多边形聚类方法与人机交互操作相比,具有速度快、精度高等特点,克服手工制图工作量大、速度慢,成本高等缺陷。To improve the efficiency of making the theme-map of forest investigation and planning, the authors discussed the methods and principles of making digital theme-map based on the Constrained recognition and clustering theory. The adjoiningmatrix of points on the earth can be made based on Constrained connection, and while it is the basic matrix with attribute-matrix of auto-clustering. Based on MapBasic and Excel, a program is made to realize the second-develop of MapInfo, the auto-combination of sub-compartment polygons can be achieved. This research is groundwork of thematie-GIS. That it not only automated the combination of sub-compartment polygons, but also raised the data quality compared with the method alternated between man and computer,this method avoids some limitations of heavy-work, low-efficiency and high-cost.
