岷山山系土地岭大熊猫栖息地廊道特征及影响因素分析

Analysis of the Characteristics and Effective Factors of the Giant Panda Habitat Corridor Establishment in Tudeling Area

本文采用景观生态学的斑块理论,根据土地岭区域前后两期森林分布信息和大量的野生动植物以及社会经济信息,详细分析了土地岭区域建立大熊猫栖息地走廊带的植被分布格局、斑块结构、廊道特征及主要影响因素,研究结果显示土地岭区域植被符合大熊猫栖息地建设条件。残余班块分布连续,占据区域森林植被的主体,有利于廊道栖息地恢复。引进斑块面积大,质量差,是廊道栖息地建设的主要改造类型。在众多的社区活动影响中,采笋的负面影响最大,最值得重点关注。基于一些主要因素的分析,作者提出了在土地岭建立大熊猫栖息地走廊带的关键措施。

Based on the patch theory of landscape ecology,according to the forest dynamic distribution,wild animals and plants as well as the socio-economic information,an analysis is made of the vegetation pattern,patch structure,corridor characteristics and the main effective factors for the giant panda habitat corridor in Tudeling area.The results have indicated the current forest vegetation is according with the selection of giant panda habitat corridor.The remains patch distributed continuously is the main type in this area,which will be helpful in the restoration of corridor habitat.The introduced patch is the biggest type in area among four patches,and its quality is poor.It is the main rebuilding type for the restoration of corridor habitat.Among many local community activities,the negative impact of mining shoots is the most worthy of attention.Based on these analyses,some key measures are put forward for the restoration of corridor habitat in Tudeling area.
