【摘要】 2008年的汶川地震发生在大熊猫集中分布的区域,对大熊猫的栖息地造成了严重破坏。利用龙溪—虹口和唐家河两个国家级自然保护区地震前(2003～2007)和地震后(2008～2010)共计7年的大熊猫监测数据,就汶川地震对大熊猫栖息地利用格局的影响进行了分析。研究结果表明:(1)地震前5年,大熊猫对栖息地的利用格局在年间没有显著变化;(2)地震后的2年间,大熊猫对栖息地的利用格局在年间没有显著变化;(3)地震前后连续7年调查的样线中,大熊猫对栖息地的利用格局在年间没有显著变化;(4)在龙溪—虹口保护区,大熊猫对样线的利用与滑坡体的面积没有显著关系,即大熊猫对栖息地的空间利用没有受到滑坡体面积大小的显著影响;(5)虽然从现有资料发现地震对大熊猫栖息地的利用格局没有显著的影响,但仍然需要在震后加强对大熊猫及其栖息地的保护。更多还原

【Abstract】 The Wenchuan earthquake of May 12,2008 occurred in the Minshan and Qionglai Mountains,where the most important habitats for giant pandas(Ailuropoda melanoleuca)occur.We took advantage of our long-term dataset on panda habitat use in Longxi-Hongkou and Tangjiahe Nature Reserves to investigate pandas’ responses to this disaster.We analyzed the habitat use patterns of giant pandas over the course of a 7-year period(5 years pre-earthquake and 2 years post-earthquake) along fixed-width line transects.The results showed:(1) Before the earthquake,there were no significant differences in used/unused frequencies each year for each transect line,in other words,the habitat use patterns of giant pandas were stable before the earthquake.(2) During the 2 years after the earthquake,there were also no significant differences in used/unused frequencies each year for each transect line.(3) Panda habitat use patterns did not appear to be affected by the earthquake since in the 10 transects surveyed before and after the earthquake,the used/unused frequencies were not significantly different between the pre-and post-earthquake periods.(4)There was no relationship between giant panda habitat use and landslides in Longxi-Hongkou Nature Reserve.Our findings contribute to ongoing habitat restoration plans and long-term conservation of the giant panda.更多还原
