摘要

Abstract

The area of giant panda habitat in North Minshan is about 5 285 km2. The 213 national highway (G213), 313 provincial highway (S313) and 301 provincial highway (S301) are around the habitat, and the habitat are divided into isolated areas due to the related human activities and the secondary provincial highways connecting G213 and S301. This environment of small regional (or patches, islands) is a potential threat to the diversity and the survival of biological species. For studying the influence of the diffusion of giant panda population among small areas on its permanence, building corridors and migrating the living environment of giant pandas are adopted to protect the giant panda. Thus, an nonlinear dynamic model of the giant panda habitat in North Minshan is developed, and the numerical simulation results shows that: After the habitat fragmentation and corridors are built among small areas (or patches), the diffusion of giant pandas will promote their permanence.
