摘要
森林资源信息的提取和制图依赖于大量空间数据的有效处理，探讨了ＡＲＣ／ＩＮＦＯ７．０．１ 和ＡＲＣＶＩＥＷ３ ．０地理信息系统在森林资源信息提取、分析及制图等方面的技术方法，并以中国东北部大兴安岭地区的塔源林场为例，对方法的具体应用作了阐述。
Information of forest resources is powerful impetus to improve the productive forces and economic development of forestry, also is the key to realize forestry sustainable development. Extraction and charting of forest resources information depends on effective process to enormous spatial data. Geographic Information System (GIS) consists of a database containing spatially referenced land related data, as well as the procedures and techniques for systematically capturing, storing, retrieving, analyzing, processing, updating, and displaying those data. GIS enables the user to manage geographic data more efficiently and enhances the decision making process for planning purposes. It has become increasingly important for spatial analysis of forest resources and forest sustainable management. The theme made inquiries about the technique of ARC/INFO 7.0.1 and ARCVIEW 3.0 in the extraction and charting of forest resources information. And taking Tayuan Forest Farm in Daxinganing Forestry Area as an example, makes a concrete exposition for the application of the new methods.
