景观多样性测度:格局多样性的亲和度分析

介绍景观格局多样性亲和度分析的原理和方法，指出亲和度分析能够测定景观各亚单元的相对位置及镶嵌多样性。镶嵌多样性是综合了亲和度分析信息的一个指标，是对格局多样性的有效测度。镶嵌多样性低意味着景观结构简单，镶嵌多样性高意味着景观结构复杂，亲和度分析可以比较不同景观的多样性和复杂性，可以判断群落与景观整体的关系的远近，还可以判断两个群落的相似性和亲和度差异的显著程度。因而亲和度分析将景观层次的多样性与物

MEASURING LANDSCAPE DIVERSITY : AFFINITY ANALYSIS OF PATTERN DIVERSITY

The paper introduced the principles and methods of Affinity Analysis in landscape pattern analysis,pointed out that affinity analysis could measure the relative positions of subunits and mosaic diversity.Mosaic diversity is a metric which combined the information in affinity analysis,is an efficient measure of compositional pattern diversity.A lower mosaic diversity means a simpler landscape structure.Using affinity analysis,the diversity and complexity of different landscape can be compared,the distances of communities to the whole landscape can be determined,and the difference degrees of similarities and affinities beteen communities can be disclosed.Therefore affinity analysis closely combined supplied landscape diversity and species diversity,a new tool for describing cross level and cross scale structures and functions of these two kinds of entities.
