摘　　要：用亲和度测度方法在不同季节对高黎贡山北段森林景观格局的多样性进行对比研究,结果表明:高黎贡山北段物种多样性的分布与海拔高度有显著的相关性,与亲和度分析结果差异很大;而且春夏两季根据平均亲和度值划分的三区有很大差异,这些差异主要来源于样方设置、调查时间和样方内物种分布不均匀。Due to resource exhaustion and environmental degradation,natural resources and biodiversity conservation has become globally hot issues.In order to protect the species,the mechanism maintaining biodiversity,at the landscape level,must be studied,and countermeasures and methods at the landscape level must be also developed.In this paper,comparative study on forest landscape pattern diversity in different seasons for the northern section of Gaoligong Mountains was implemented with the Affinity Measure Methods.Results showed that the distribution of species diversity was in a significant correlation with altitude,which was significantly different from the results of the affinity analysis.Meanwhile,three zones divided on the basis of average affinity values in spring were obviously different from that in summer.These differences mainly come from quadrat setting,investigation time,and uneven distribution of species within the quadrat.
