摘要:

珲春国家级自然保护区是东北虎(Panthera tigris altaica)、东北豹(Panthera pardus orientalis)等濒危物种在中国的核心分布区。为了探究该区域野生动物的多度水平和空间分布, 了解人类干扰情况, 我们运用相对多度指数(relative abundance index, RAI)分析了2013年4-6月设置于此的83个红外相机位点的监测数据。红外相机的总捕获天数6,060 d, 共捕获10科18种野生哺乳动物, 其中鼬科4种, 猫科动物3种, 犬科、鹿科和松鼠科各2种, 猪科、熊科、麝科、猬科和兔科各1种。研究期间共拍摄到东北虎11只个体, 东北豹13只个体。从相对多度指数来看, 东北虎的相对多度(0.84)远高于东北豹(0.48), 它们的有蹄类猎物中梅花鹿(Cervus nippon)的相对多度最高(2.18), 其次为狍(Capreolus pygargus)(1.53)和野猪(Sus scrofa)(0.92)。人类活动和放牧的相对多度水平(分别为40.64和2.76)显著高于野生动物。在空间分布上, 东北虎和梅花鹿主要在保护区的核心区分布, 且与保护区社区共管区的多度水平差异显著, 而东北豹在不同功能区之间的分布差异不显著, 狍在保护区北部的多度水平较高, 但各功能区之间差异不显著, 野猪在社区共管区的多度水平显著高于核心区。可见, 核心区频繁的人类活动和放牧活动对野生动物的保护产生了影响, 未来应加强关于人类干扰对虎、豹种群及其有蹄类猎物的影响评估。

Abstract:

The Hunchun National Nature Reserve (HNNR) serves as core habitat for both Amur tiger (Panthera tigris altaica) and Amur leopard (Panthera pardus orientalis) in Northeast China. To investigate the relative abundance of wildlife and human disturbance within the reserve, we analyzed images from a monitoring network of 83 camera traps deployed between April and June of 2013 in HNNR. Among the 6,060 total trap nights, 18 species of mammals were detected from the images, including four Mustelids, three Felids, two species each from Canidae, Cervidae and Sciuridae, and one species each from Suidae, Ursidae, Moschidae, Erinaceidae and Leporidae, respectively. Cameras photographed 11 tigers and 13 leopards. Relative abundance index (RAI) of tigers (0.84) was higher than that of leopards (0.48). RAIs of ungulates, from high to low, were sika deer (Cervus nippon) (2.18), Siberian roe deer (Capreolus pygargus) (1.53) and wild boar (Sus scrofa) (0.92). RAI of human activities (40.64) and livestock grazing (2.76) were both significantly higher than animal species. The data also indicated that tigers and sika deer were mainly restricted to the core zone of HNNR and that their abundance was lower in the community-based natural resource management zone. In comparison, RAIs of Amur leopard were fairly similar among the three functional zones, Siberian roe deer tended to be more abundant in the northern section of HNNR but differences were not significant, and wild boar RAI was lower in the core zone. Frequent disturbance from human activities and livestock grazing throughout the core zone may be the most negative impact on wildlife in HNNR.
