摘　　要：在3S技术和Fragstats 4.0支持下,运用景观生态学原理,通过多种指数,从类型水平和景观水平上对南岭国家级自然保护区乳阳片区的森林景观斑块进行了较为全面的分析。结果表明:常绿阔叶林是乳阳片区的基质景观类型,斑块类型面积为19 759.53hm2,占整个森林景观的64.43%;景观要素斑块类型面积大小排序为常绿阔叶林﹥针叶林﹥落叶阔叶混交林﹥针阔混交林﹥采伐迹地﹥山顶阔叶矮林﹥山地草甸﹥道路﹥建设用地﹥水域﹥耕地;整体景观斑块彼此相邻近,各级景观斑块分布均匀、规模适中、形态自然、破碎程度低。With the support of 3 S technology and Fragstats 4.0 and by using the landscape ecology principle,the authors analyzed the forest landscape patterns of Ruyang area in Nanling National Nature Reserve through a variety of landscape indexes,type level and landscape level.The results showed that evergreen broad-leaved forest was the main type in Ruyang area for the reason that the area of evergreen broad-leaved forest landscape was 19759.53hm^2,which accounted for 64.43%of the total area.The results also showed that the scheduling of the area of each patch type was as follows：evergreen broad-leaved forest〉coniferous forest〉deciduous broad-leaved mixed forest〉mixed needle〉cutting blanks〉the mountain broad-leaved thicket〉mountain meadow〉road〉construction land〉waters〉arable land.The patches of the whole landscape were adjacent to each other,spatial distribution was in equilibrium,spontaneous shape and the fragmentation degree was low.
