景观连接度的概念、度量及其应用

The concept and measurement of landscape connectivity and its applications

景观连接度是指景观促进或阻碍生物体或某种生态过程在源斑块间运动的程度,反映了景观的功能特征。景观连接度理论与方法是景观评价、管理和生态规划的重要基础,对于区域可持续发展和生物多样性保护等方面的研究都具有重要指导意义。综述了国内外近10a来有关景观连接度概念、度量方法及其生态学意义的最新进展,并探讨了景观连接度与景观要素间的关系及其潜在应用前景,以期为深入开展景观空间格局与生态过程间关系的研究与应用提供参考。

Landscape connectivity was defined by metrics to reflect landscape functional characteristic for it represents ＇the degree to which the landscape facilitates or impedes movement among resource patches＇.The theory and method of landscape connectivity is an important basis for landscape evaluation,management and ecological designing.It will also contribute to the regional sustainable development and biodiversity conservation.In this paper,the new progress of landscape connectivity research,including the concept,measurement and its ecological significationce were summarized,and the relationship between landscape connectivity and landscape elements,and its potential application perspectives were discussed.This review could serve as a guideline in further research and applications of the relationship between landscape pattern and ecological processes.
