摘 要 ：以金沟岭林场为例 ,利用电子林相图和森林资源二类调查资料基础 ,借助 GIS软件 Map Info和数字化仪跟踪矢量化 ,并运用景观生态学原理和方法 ,选取分维数、分离度斑块密度、景观优势度和均匀度等指标 ,对林场的景观格局进行了分析 ;同时采用类平均聚类法 ,选取分维数、分离度、斑块平均面积、最大斑块面积 4个景观类型特征指数作为聚类分析的聚类因子 ,进行定量地划分森林类型 ,合理地区划森林经营类型 ,为优化景观水平配置、制定生态采伐规程、编制森林经营方案提供理论基础。

Abstract:The scientific and reasonable division of forest resources is one of important means to realize forest sustainable management. Due to using unreasonable cutting methods and human destruction,forest resources are being deficient and ecological environment have gotten degenerated gradually. Therefore,the purpose of the paper is to find a way of ordinating the relationship between cutting and environment conservation. Based on the landscape ecology theory and the application of GIS,this paper studies the fores...
