以森林资源二类调查数据为基础，采用PLAND指数、MPS指数、AI指数、PAFRAC指数、SHDI、SHEI指数对贵州佛顶山自然保护区景观格局特征进行分析。结果表明：在以地类划分的景观中，林地斑块占主体（91.93％），其中尤以纯林斑块面积最大（61.76％），且斑块完整性最高；在以林分起源划分的景观中，天然林斑块面积占总面积89.19％，且斑块破碎化程度低，保存完好，但原生林面积比例极小（0.49％）；在功能分区中，核心区多样性指数和均匀度指数均最低，且核心区斑块异质性低、破碎度低、人为干扰较少，表明保护区功能分区的核心区划定较为合理。

Fodingshan Nature Reserve is important served as a bio-corridor to build the network of Nature Reserves in the east and southeast of Guizhou province.So,based on the data of Secondary Forest Resources Inventory ,several indices of landscape ecology such as PLAND、MPS、AI、PAFRAC、SHDI and SHEI were calculated to analyze the characteristics of landscape of Fodingshan Nature Reserve by using the software ARCGIS and FRAGSTATS .The results showed that ,the forest land patches are dominate (91.93%) and pure stand patches account for the bulk of it (61.76%) with better integrity than other patches;while the landscape divided by the origin of stands ,the patches of natural stands account for 89.19%of total area with lower fragmentation than other patches ,but the primitive stands are very rare within it;in the aspect of functional zone of Nature Reserve ,both of SHDI and SHEI of Core Zone are lower than other zones ,which indicate that the division of Core Zone is reasonable because of its lower heterogeneity of patches , lower fragmentation and lower disturb of human′s activities.Eventually,we can conclude that the forest community of Fodingshan is dominated by natural secondary stands with a relative short history of natural succession ,which can be illustrated as a stage of suc-cession that from competitive succession to climax stage ,so,strengthening the protection of natural resources is very important in or-der to prevent the converse succession caused by disturb of human beings .
