森林景观格局是森林景观生态学研究的核心。本文以林场1∶5万的地形林相图及小班调查数据为基本资料,建立森林景观二级分类体系;利用GIS技术,选取景观要素斑块特征指数(类斑近圆指数、分维数)、景观异质性指数(斑块边缘密度、多样性指数、优势度)、景观要素空间相互关系分析指数(联系度、聚集度),系统地分析了林场的森林景观格局,以期在此基础上实现森林景观的优化配置。
Forest landscape pattern is the core of forest landscape ecology research. In this paper, based on topographical forest phase diagram and small-scale survey data of 1: 50000 forest farms, a two-level classification system of forest landscape was established. By using GIS technology, the feature indices of plains (near-circular index and fractal dimension) The landscape heterogeneity index (patch edge density, diversity index, dominance), landscape spatial correlation analysis index (degree of association, degree of aggregation), systematically analyzed the forest landscape pattern of the forest farm on the basis of which Optimized allocation of forest landscape.
