广东南岭国家级自然保护森林景观格局分析（英文）

目的]分析南岭国家级自然保护区森林景观格局,为该保护区的森林生态系统的保护提供支持。方法]以1∶10 000地形图、森林资源二类调查数据和实地补充调查数据为基础资料,基于GIS平台和Fragstats软件,运用景观生态学原理和景观指数分析方法,对研究区内森林景观的格局和异质性进行分析。结果]森林景观类型面积大小依次为常绿阔叶林、针叶林、针阔混交林、阔叶混交林、灌丛、针叶混交林、宜林地、落叶阔叶林和非林地。结论]研究区域森林景观格局分析表明,保护区景观异质性较高,连通性较好,破碎化程度不明显,各景观组分的面积和比例分布极不均衡,常绿阔叶林和针叶林等少数几种组分在景观中占绝对优势。

Analysis of Forest Landscape Pattern in Nanling National Nature Reserve,Guangdong

Objective] The study was to analyze the forest landscape in Nanling Na- tional Nature Reserve to provide information for the protection of local forest ecosys- tems. Method] With the documents of 1：10 000 topographic maps, updated Forest Resource Inventory Data, based on the GIS platform and Fragstats software, the paper analyzed the patterns and heterogeneity of forest landscapes by adopting the landscape ecological theory and the method of landscape index. Result] The forest landscape types, in terms of area occupation from large to small, are in the order of evergreen broad-leaved forest, coniferous mixed forest, evergreen and deciduous broad-leaved mixed forest, shrubs, mixed needle leaf forest, suitable land for forest deciduous broad-leaved forest and non-forest. Conclusion] Overall, the Reserve had maintained sufficient forest landscape diversity with a low level fragmentation. The distribution of various types of forest landscape was extremely uneven, dominated by several types such as evergreen broad-leaved forest, coniferous forest, etc.
