Home Range and Habitat Utilization of Wolves during Winter in Hulunbeir, Inner Mongolia
【摘要】 2004年冬季,在内蒙古呼伦贝尔市达赉湖自然保护区对狼的家域和生境利用状况进行了调查。通过跟踪狼的雪地(或沙地)足迹,记录狼的活动情况和家域标记点(尿或粪等)的地理坐标,运用最小凸多边形法计算狼的家域。结果显示达赉湖地区狼的家域为112km2。在狼的巢域内,狼的洞穴主要选择芦苇草原生境,选择率为95.45%。捕食生境主要为牧民点,选择率为57.14%。
【Abstract】 An experiment was conducted to study the home range and habitat utilization of wolves in Dalai Lake Natural Reserve, Hulunbeir, Inner Mongolia during winter in 2004. The activity of wolves and the geographical coordinate of their home range markers, including urine and feces, were recorded by tracking them on the snow ground or sandlot. Their home range was estimated by the minimum convex polygon method. Result showed that the home range of the wolves in Dalai Lake is 112 square kilometers. In the home range, the most important habitat of dens is the reed grassland with the selectivity of 95.45%. Wolves primarily prey upon livestock in residential area with the selectivity of 57.14%.
