摘要
在景观生态学研究中 ,理解与把握景观格局变化的生态学原则至关重要 .用景观指数描述景观格局及变化 ,建立格局与景观过程之间的联系 ,是景观生态学最常用的定量化研究方法 .本文在综合前人对景观指数的基础上 ,对景观指数研究从景观指数的分类研究、指数对景观格局的描述研究、指数之间的相关性研究及指数构建研究等 4方面进行了总结 。
In landscape ecology,it is very important to understand and grasp the ecological principles of landscape transformation.One of the research methods in common use is to describe landscape pattern and its transformation,and then connect landscape pattern with process by means of landscape indices.Based on the previous studies on landscape indices,some researches on the landscape indices' classification,descriptive ability,relationship among indices and indices' creation were conducted in this paper.Moreover,the general principles of applying landscape indices from two different levels,namely,from single index level and from index system level,were put forward.
