Topographic differences for vegetation types in Wuyishan National Nature Reserve, Fujian Province

摘要: 为探讨地形对中亚热带森林植被分布的影响，在利用地理信息系统技术提取研究区域各地形因子和植被景观信息基础上，分析了福建武夷山国家级自然保护区植被景观和地形的总体特征，揭示了植被分布在地形上的变异规律。结果表明，区内各植被类型面积分布不均，地带性植被常绿阔叶林和针阔混交林是主要植被类型，占总面积的70.53%。在海拔的影响下，保护区植被有明显的垂直分带现象。坡度和坡向对不同植被类型分布影响程度不同，只对中山草甸、阔叶矮曲林和人工植被等3种植被类型有较显著影响。从各植被类型在海拔、坡度和坡向上的变异系数看，海拔因子对植被类型的分布影响最大。

Abstract: The objective of this study was to explore the influence of topography on the distribution of mid-subtropical forest vegetation types. Topographic characteristics and vegetation landscape in the Wuyishan Nature Reserve of Fujian Province were determined using a Geographic Information System (GIS) technique and were then analyzed to disclose topographic vegetation distribution differences. Results showed nine vegetation types in the Wuyishan Nature Reserve with zonal evergreen broadleaf and coniferous-broadleaf forests being the main vegetation types and occupying 70.53% of the total area. Forest vegetation had a vertical zonal distribution due to elevation. Slope and aspect had a prominent effect on subalpine meadows, broadleaf coppice forests, and cultivated vegetation types. The coefficients of variation for vegetation types showed that elevation was the most important factor to the distribution of the vegetation.-
