摘要

岷山北部大熊猫栖息地的总面积约5 285 km2

周围分布着213国道(G 213)

313省道(S313)和301省道(S301)三条主要公路.连接213国道和301省道的次要公路及相关的人类活动造成这个地区大熊猫栖息地破碎化

这种环境小区域化(或称斑块化、岛屿化)现象对生物种群的生存和多样性是一个潜在的威胁.为了研究大熊猫种群在小区域之间的扩散对持续生存的影响

提出采用构筑廊道

让大熊猫种群迁移生存环境等措施

以保护大熊猫.为此建立了岷山北部大熊猫栖息地内的非线性动力学模型

计算机数值仿真证明:在大熊猫栖息地裂成小区域后

如果在局部小区域之间构筑廊道

则大熊猫个体在各个小区域(斑块)之间的扩散有利于大熊猫种群的持续生存.

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.
