摘要
指出了景观破碎化是当今世界一个突出的生态学问题,物种多样性的变化也是全球生态学的热点问题。重点阐述了破碎化斑块的面积、形状、密度等因素对斑块内部物种多样性影响程度,以及边缘效应、背景效应等对斑块边缘物种多样性的影响程度,探讨了景观破碎化对物种多样性的影响。
Landscape fragmentation is a prominent ecological problem in today’s world. The change of species diversity is also a hot issue in global ecology. This paper focuses on the extent of the fragmentation plaque’s area,shape,density and other factors on the species diversity within the plaque,as well as the effect of edge effects and background effects on the species diversity of plaque margins. It also analyzes and summarizes the impact of landscape fragmentation on species diversity.
