摘要
2002～2003年，对九寨沟国家级自然保护区的大中型兽类进行了6次大规模的调查。共调查大中型动物样线82条，实际调查记录到大中型兽类20种，样线上遇见各种大中型兽类痕迹或实体总计223次，均用GPS进行精确定位。统计表明，针叶林生境中物种最丰富；随海拔增高，总的趋势是古北界种类所占比例呈现增加趋势，但在海拔3600～4000m之间，东洋界种类所占比例仍然较大（50％），动物区系呈现广泛的过渡性；随着海拔升高古北界种类样线的遇见率明显增加，3200m以上这种趋势更为明显。在记录到的20种大中型兽类中，豹猫（Felisbengalensi）分布的海拔跨度最大，为保护区的广布种；牛羚（Budorcas taxicolor）的遇见次数最多，是保护区的优势种。
From 2002 to 2003, the diversities of large and medium mammals were surveyed. Six separate surveys were conducted there during this period. Totally, 20 species of large and medium mammals were found in 82 routes surveyed and trails or individuals of them were met for 223 times there. The locations of meeting trails and individuals were pinpointed with GPS. As a result, the species were the most abundant in conifer forest. There is a general trend for an increasing proportion of Palaearetic mammals with elevation ascending. However, the proportion of Oriental mammals is still 50% between 3600 m and 4000 m. This indicates the mammal fauna is broadly in transition in this area. At the same time, founding that the meeting frequencies of the Palaearetic mammals is obviously increasing in routes surveyed with ascending of elevation, and this trend shows more and more obvious above 3200 m. Among the 20 mammals, The distributing span of elevation of leopard cat （Felis bengalensi） is broadest（from 1996-4000m） and it is a wide-distributing species in this area. During surveys, takins （Budorcas taxicolor） were found at best, and it is a preponderant species in this area.
