摘要
以汤旺河林业局1988年和2008年两期林相图、地形图和森林经理调查数据为基础资料，利用地理信息系统软件ArcGIS9构建两期森林资源空间数据库，运用叠加分析法对6种地类、7种林型和2种起源的森林资源的空间消长情况进行研究的结果表明：1988--＇2008年，有林地作为该地区的优势景观要素，面积增加了9．38％；红松林、落叶松林面积分别减少了86．71％和33．1％，白桦林、杨树林等阔叶林分面积不同程度增长；天然林和人工林面积之比稳定在11：1，呈不均衡状态。
This article is based on the forest type map, topography and survey data of Tangwanghe Forestry Bureau in 1988 and 2008,using geographic information system software ArcGIS9 to build forest resource spatial database, as well as applying overlay analysis to research the forest resources spatial dynamics of six category, seven forest types and two origins. The results showed that from 1988 to 2008, the forestwhich was the local advantage landscape elements, its area increased by 9.38%; the area of Pinus koraiensis forest and Larix gmelinii forest were reduced by 86.71% and 33.1% respectively; the area of broadleaved forest, such as Betula platyphylla forest and Poplar forest, increased in different extent; The area ratio of the natural forest and plantation forest stayed at 11：1, taking on an unbalanced status.
