| 中文摘要: |
| 中国的野生东北虎(Panthera tigris altaica)数量已降到了极低的状态,及时开展有关东北虎及其猎物资源野外调查,对了解东北虎生存现状和制定保护策略都具有重大意义。吉林珲春东北虎国家级自然保护区是我国现存东北虎活动最频繁的地区之一,为了解该保护区的东北虎及其猎物资源状况,2009~2010年冬季,采用样线法对保护区及周边地区的东北虎及其猎物资源进行了系统调查。结果显示,调查期间在1 182 km2的调查范围内至少有3只东北虎活动,确认性别的为2雄1雌。以新鲜足迹链遇见率表示的猎物相对密度(条/km)分别为: 马鹿(Cervus elaphus)0.09、狍(Capreolus pygargus)0.43、梅花鹿(Cervus nippon)0.12、野猪(Sus scrofa)0.03;实体密度(只/km2)分别为: 马鹿0.11、狍0.76、梅花鹿0.07、野猪0.01,都低于俄罗斯远东地区的猎物资源量。人为活动(林蛙养殖场、采集山野菜、季节性采伐和放牧)、栖息地破碎化、盗猎等是造成东北虎及其猎物密度较低的主要原因。尽快停止保护区周边的采伐、控制林蛙场的数量、打击盗猎、限制放牧范围是恢复东北虎栖息地和保护猎物资源的重要措施。 |
| 英文摘要: |
| The Amur Tiger (Panthera tigris altaica) is critically endangered and there is no confirmed viable population in China.In the winter of 2009-2010, we conducted a field survey in and surrounding the area of Hunchun Amur Tiger National Nature Reserve using line transect method.There are 3 tigers 2 male and 1 female at least found in the surveyed area of 1 182 km2 in size and they are transient individuals between China and Russian border.The relative density of ungulate prey is 0.09 for Red Deer (Cervus elaphus), 0.43 for Roe Deer (Capreolus pygargus), 0.12 for Sika Deer (Cervus nippon), and 0.03 for wild Boar (Sus scrofa) by tracks/km, or 0.11, 0.76, 0.07, 0.01 by individial/km2 respectively.These values are much lower than those in Russia.Poaching ungulate and habitat fragmentation by human activities, such as small villages attached with cropland patches, frog breeding farms, seasonal logging, collection of wild plants and cattle grazing, were the main reasons for tiger number and ungulate prey declining.Logging ban around the nature reserve, controlling human activity at frog breeding farms, enforcing punishment on poaching, and limiting cattle grazing ranges as soon as possible are fundamental ways to rehabilitate tiger habitat and protect ungulate prey. |
