摘要
以武冈林场2003年森林资源调查资料为数据源,结合武冈林场的地形地势与区位特征,利用ArcInfo强大的空间分析与数据管理功能,按照森林的功能类型及森林区划技术标准,将武冈林场的森林资源划分为商品林和生态公益林2个类型,在此基础上,二级区划分为4个林种,三级区划分为9个林种;其次按公益林事权等级,划分了国家级公益林3966.1hm2、省级1003.0hm2、市级342.8hm2.实现了森林分类区划界定的自动化、可视化及图形化;为森林分类经营提供了科学依据.
Based on the forest management inventory data of 2003 and the geographical peculiarity of the investigated region, a case study was carried out of the forest classification division on Wugang forest farm, using ArcInfo's powerful function of data analysis and management. According to forest function types and division technical criteria, the forest resources were divided into two kinds: public benefit forest and commercial forest. Moreover, four first-rank forest categories and nine second-rank forest categories were established. Furthermore, Qccording to the principle of preserved grades for public benefit forests, the resources were plotted out as the national, provincial and municipal public benefit forests that are respectively 3966.1 hm^2, 1003.0 hm^2 and 342.8 hm^2. Therefore, automatic, visual and graphic forest classification division was achieved, offering a scientific foundation for forest classification management.
