摘  要：
选取雾灵山10个主要森林景观类型,通过比较这些森林景观类型的物种多样性和相关的环境因子,揭示了这些景观类型物种多样性的差异,与环境因子的关系,及其空间分布规律。结果显示:各森林景观类型乔木层物种丰富度均较低,灌木层和草本层物种丰富度较高,大部分景观类型的物种丰富度均表现出:草本层>灌木层>乔木层的特点;各森林景观类型的Simpson指数和Shannon指数同物种丰富度具有相似的规律。根据平均相似度值,对这些森林景观类型进行了排序。运用亲和度分析方法测度景观格局多样性,根据平均亲和度值,可将这些森林景观类型划分为中心点、中间点和外点三部分。

摘  要：
A total of 10 main forest landscape types were chosen in this paper.By comparing species diversity and the environmental factors,the differences among these types,their correlation to the environmental factors,and their spatial distributing regularity were disclosed.The results show that,Species richness of tree layer was low.Whereas it were higher in shrub and grass layers in all these forest types.The vertical structure of species richness was grass layer> shrub layer> tree layer in most forest types.Shannon index of the forest types had similar regularity with that of species richness.According to mean similarity,carried on to these forest landscape types arranges.And measured the diversity of landscape pattern with the analysis of mean affinity.These main forest types could be divided into 3 parts according to the mean affinity,modal sites, moderate sites and outlier sites.
