| 摘 要： | 2006年1月至2008年12月,在内蒙古赛罕乌拉国家级自然保护区运用样线法和粪便分析法,对狼(Canis lupus)的生态分布和食物组成开展了研究。研究结果:保护区狼的数量至少7只,密度为(4.18±2.88)只/100km2,主要分布于保护区的圣山和庆云山核心区。在圣山主要活动于山脊、道路和沟谷;在庆云山主要活动于山脊。草兔(Lepus capensis)和植物在狼的食物组成中出现率最高,其食物组成在年度间存在显著差异(P<0.01),冬春与夏秋季节间差异不显著(P>0.05)。

| Abstract: | To provide initial value for population restoration and management of wolves (Canis lupus) in the wild, line transect survey and fecal analysis method were used to study the population ecology of wolf at Saihanwula National Nature Reserve, Inner Mongolia. The results revealed that the population number was at least seven within the reserve and population density was 4.18+/-2.88 individual per 100 km2. The wolf population was mainly distributed in Shengshan and Qinyunshan core areas; active sites appeared mostly along mountain ridges, roads and valleys at Shengshan and mountain ridges at Qinyunshan. Hare (Lepus capensis) and plants occurred frequently in the food composition of wolf scats. Food types varied between years but not seasons (Winter-Spring and Summer-Autumn). |
