摘　　要：景观多样性是生物多样性研究的主要内容之一,在生物多样性保护方面具有重要作用。本文运用景观生态学原理,借助地理信息系统技术,选取景观多样性、优势度、丰富度密度、均匀度、分离度、分维数等指数,分析了南宁市青秀山风景名胜区不同景观类型的空间分布特征。结果显示:整个研究区域的多样性丰富,各景观类型所占比例相对均匀,常绿阔叶林和马尾松林的破碎化程度较轻,经济林和农田等人工景观较破碎,表明人为干扰十分强烈。Landscape diversity is a main content of biological diversity. It plays an important role in biodiversity conservation. In this paper, according to the theory of the landscape ecology and by means of GIS technology, the indices related to landscape diversity,landscape dominance ,evenness, mean patch fractal dimension are chosen and the spatial structure of landscape diversity in Qingxiushan mountain scenery area in Nanning city is analysed.The results indicate that the landscape diversity index is very high, the areas of each landscape are comparatively equal, the landscape fragmentation of the evergreen broad-leaf forest and p.massoniana is lower than that of the others while the farm land and orchard landscape fragmentation is the highest, which indicates that the forest in Qingxiushan mountain is disturbed intensively by human activities.
