中文摘要:
四川唐家河国家级自然保护区是大熊猫的主要的保护区,同时也是另一种国家一级保护动物羚牛( Budorcas taxicolor)的集中分布区,在习性方面,羚牛夏季在高山草甸和针叶林区域集群出现,并伴有用角、躯干摩擦乔木的树干或者其他粗糙的表面的擦痒行为,会对本身就脆弱和敏感的针叶林树造成一定的损伤,随着保护区保护力度的加大,羚牛的种群数量在近二十年内快速增长,而其对亚高山针叶林的利用强度也在增大,目前尚不清楚这种利用强度对针叶林造成的损伤的程度有多大。作者于2016年3月-5月运用抽样法、临摹法、侧面积法对唐家河大草堂区域的亚高山针叶林受羚牛擦痒行为造成的树皮受损特征做了统计调查,并在2000海拔的红石坝区域设置了对照组,通过数据收集、处理、分析,发现随着海拔的增高,树木受损的比例和伤口大小都有增长的趋势,另外羚牛在对擦痒树木的选择上,对树的胸径等没有选择性差异,但在低海拔的红石坝区域,羚牛擦痒对不同种类的树的选择上存在差异。
外文摘要:
Sichuan Tangjiahe, the national nature reserve, is the main of the giant panda reserves,and is as well as the concentration distribution area to protect the takin (Budorcas taxicolor), which is another animal at the national level protect animals. In terms of habits, takins are often appeared with groups in alpine meadow and coniferous forest area in the summer, which is accompanied by using ox horn and body to damage tree trunk friction or other rough surface, this is called as wipe behavior. This will be caused certain damage on fragile and sensitive coniferous trees. Along with the increase of reserve protection, takins’ population quantity is growing quickly in recent 20 years. On the other hand, this make the intensity of its use of subalpine coniferous forest increasing. Meanwhile, it is unclear whether the extent of the damage will cause using intensity of coniferous forest or not. From March 2016 to May 2016, we use sampling method, copying method, and lateral area method to research and make the survey, which be found that subalpine coniferous forest’s bark damage characteristics are caused by wipen itch behavior in Tangjia River Big Thatched Cottage Area . And we set up the control group in the altitude of 2000 red dam area. Through data collection, processing and analysis, we find as the altitude increase, the ratio of damaged trees and the trend of wound size increase. Moreover, takins have no selective differences in itch to wipe on the choice of trees, diameter at breast height of trees, and so on. However, takins’ wipe itching for the choice of different kinds of trees is not the same in low altitude red and rockfill dam area.
