MEASURING LANDSCAPE DIVERSITY : AFFINITY ANALYSIS OF PATTERN DIVERSITY
景观多样性测度:格局多样性的亲和度分析

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.
