摘　　要：以林相图制作为例,分别利用ViewGIS、ArcGIS对2009年广西省八步区桂岭镇森林资源二类调查数据进行编辑处理,并在ArcGIS中完成了平桂管理区及八步区所有乡镇林相图的制作,在此基础上对比分析总结,提出了基于GIS的林业专题制图优化方法。实验结果显示,在ViewGIS中矢量化及建立拓扑关系,提高了矢量化的效率和精度,在很大程度上缩短了拓扑建立的时间,并实现了小班的自动编号。ArcGIS中模板和符号库的制作及应用,一方面节省了制图时间,另一方面保证了同一专题的专题图表现风格的一致性及整体美观性。经实践,该优化方法能有效提高林业专题图制作效率,且成图更为规范美观。Taking stock map making as an example, the data of Forest Management Inventory in 2009 of Guiling town, Babu district, Guangxi, were edited and processed by using ViewGIS and ArcGIS respectively, and the stock maps of all towns in Pinggui and Babu were completed in ArcGIS. The optimization of making methods for forestry thematic map based on GIS were proposed on the basis of comparative analysis and summary. The experimental results show that the vectorization and building topology in ViewGIS improved the efficiency and accuracy of vectorization, shortened the time building topology greatly, and realized automatic numbering of sublots. The designing and using of template and symbol library in ArcGIS saved drawing time on one hand, and ensured consistency of performance style while making the same thematic map on the other hand. The practice prove that this optimization method can improve the efficiency of forestry thematic map making, and draw more normal and beautiful maps.
