摘要:

生境破碎化与生物多样性的关系是理论生态学的研究热点。本文在综述国内外相关研究内容的基础上,阐述了生境破碎化的概念内涵与度量,介绍了生境破碎化研究的主要理论基础、研究内容与研究进展;总结了目前生境破碎化研究存在度量破碎景观格局的方法尚未统一、研究方法有待精确以及生境破碎化与生物多样性的阈值效应尚未发现等问题。今后,半干旱地区生境破碎化对生物多样性影响的研究需要加强,空间分析理论和方法将会在生境破碎化对生物多样性影响的研究中得到更多应用。

Abstract: The relationship between habitat fragmentation and biodiversity has been a hot spot in theoretical ecology. This paper elaborated the concept, connotation and measurement of habitat fragmentation. The main theory, content and progress of habitat fragmentation research were also described. Many issues of habitat fragmentation studies were summarized such as different metrics methods of fragmented landscape pattern, inaccurate research methods and undetected nonlinear effect of habitat fragmentation. More research should be conducted on the effect of habitat fragmentation on biodiversity in semiarid areas. Furthermore, the theory and methods of spatial analysis should be widely applied in this area.
