摘要
本文以制作四川省全国重点保护野生植物资源图为例,介绍了利用地理信息系统绘制林业专题图,包括属性信息数据库的建立、空间信息数据库的建立以及资源图的绘制等过程,还提出了绘图时的一些技巧以及应注意的问题。用这种方法比传统手工制图快捷、准确、灵活。
As a part of the digital globe,the digital forestry will promote the reformation of the traditional forestry.Acording to a case of drawing the maps of the national important protecting wild plant resources in Sichuan province,researches are made on how to use GIS for drawing the special maps of forestry,including the processes of the foundation of the attribute information database,the space information database,and drawing the maps of the resources.At the same time,some skills and problems which should be noticed during drawing the maps are also brought forward.
