摘　　要：【目的】进行大尺度的大熊猫生境研究,为制定合理的保护对策提供依据。【方法】利用海拔、坡度、坡向、汇流、植被数据构建反映卧龙自然保护区生境特征的多波段数据site。分别采用ISO生境分类法和n-D可视化工具,得到大熊猫潜在适宜生境和大熊猫实际利用生境区域评价结果。【结果】地形和植被类型是大熊猫栖息地选择的重要影响因素。在卧龙自然保护区内,两种方法所划分的大熊猫生境皆具有暖坡比例大于冷坡的特点,暖坡比例随海拔升高而增加。卧龙大熊猫栖息地海拔范围在1 820~3 051 m之间。栖息地平均海拔3 000 m。大熊猫分布密度最大的区域平均海拔为2 500 m。卧龙大熊猫倾向于选择海拔较低,暖坡比例更高的微生境。可能受人类活动影响,卧龙保护区大熊猫有沿着河谷向高海拔拓展活动范围的趋势。【结论】两种方法得到的大熊猫生境具有较大空间一致性。【Objective】Study the large-scale habitat of giant pandas,to provide the basis for makingreasonable protection strategies.【Methods】Use elevation,slope,slope direction,flow Accumulation,vegetation data to construct a multiband site data,to character the environment of the Wolong NatureReserve.ISO method was adopted to classify the date site into four classes according to the tracesnumber of giant panda in each classes,to detect the panda's potential suitable habitat.By employ n-Dvisualization tools,the giant panda trace points was divided into four types,and supervised classificationwas carried out on the date site,then determined the habitat of giant panda actual use area.【Results】The topography and vegetation type is one of the important factors affecting the giant panda habitatchoice.And giant panda intent to choose warmer slope more than cold slope,as altitude increasing,ratio of warm slope increased in panda habitat.Elevation of giant panda habitat range from1820m to3051m.But giant panda is most like the region with average altitude of2500m.Wolong giant pandatend to choose microenvironment with lower altitude,and higher warm slope ratio.May be affected by human activities,Wolong giant panda have expand their habitat along valley to higher altitude.【Conclusion】Giant panda habitat that getting from two methods has a bigger space consistency.
