景观破碎化与生物多样性的相关性
Landscape Fragmentation and Biodiversity Relativity
摘要
Abstract
Landscape fragmentation and biodiversity importance was one of the “bottlenecks” that restricted the diversity of biology. Human disturbance and habitat islands were the main reasons for the formation of landscape fragmentation. Landscape fragmentation changed the geographical environment for the survival of biological species. Survival spaces of species dropped, reducing biological diversity and the characteristics of the ecosystem changed, influencing the flow of material within the system and energy balance and intensifying the destruction of the ecosystem; the patch area, patch density and spatial structure changed, resulting in changes of landscape pattern and reducing the variety of landscapes. The above analysis aimed to better understand the biological diversity of landscape fragmentation on the profound impact. In addition, the implementation of measures to reduce fragmentation was analyzed.关键词
