大熊猫黄土梁廊道景观破碎化进程分析

Process Analysis of the Landscape Fragmentation of Huangtuliang Panda Corridor Based on Landscape Ecology

大熊猫黄土梁廊道,是连接岷山山系大熊猫栖息地A块的中北部的关键区域。本文根据景观生态学理论,运用景观分析软件FragStat3.3,从斑块类型和景观类型两个尺度,对不同时期(1975年、1992年、2010年)该区域大熊猫栖息地景观指数特征进行了分析,研究了黄土梁廊道景观破碎化进程,并对影响大熊猫黄土梁廊道的因素进行了分析,为大熊猫黄土梁廊道的保护提供参考。

Huangtuliang Panda Corridor is the critical area connected to the giant panda habitat of A pop- ulation on the Minshan Mountain. Based on the theory of landscape ecology, the software FragStat 3.3 was used to analysis of giant panda habitat characteristics in the different periods （1975,1992,2010） and studies were made of landscape index, and the process of landscape fragmentation from two dimensions of patch types and landscape types. The results showed that the giant panda habitat fragmentation was very serious in the past 35 years.
