- 摘要:
- 以鞍山大麦科湿地自然保护区为例，对景观格局的景观指数描述方法进行了探讨。景观指数是指能够浓缩景观信息，反映其结构组成和空间配置某些方面特征的简单定量指标。景观格局特征可以在三个层次上分析，相应地景观格局指数亦可分为三个水平，即斑块水平指数、斑块类型水平指数以及景观水平指数。当前，用于描述景观格局的许多景观指数不满足相互独立的统计性质，因而说服力不强。选取了典型性的四种指数对景观格局进行了勾画。结果表明，实际应用中只用少量指数即可完全满足格局分析的需要，反映出研究区景观格局的特点。
- Abstract:
- The landscape index in landscape pattern is discussed with a study case of Damaike nature reserve in Anshan. Landscape index is a sort of simple quantitative index that can concentrate landscape information and reflect the structure and characteristic. Landscape pattern may be studied on three levels, including patch level index, patch type level index and landscape level index, so landscape index can be discussed on three levels. At present, many indexes are used to depict landscape pattern, but many of them can’t express the landscape pattern because they are not independent. Four typical indexes are selected and used to sketch the landscape pattern. Result indicates that a few indexes reflecting the characteristic of landscape pattern should be selected in practice.
