白头叶猴栖息环境与栖息地选择的研究

HABITAT VEGETATION AND SELECTION OF WHITE-HEADED LEAF MONKEY(TRACHYPITHECUS LEUCOCEPHALUS)

通过样方法和焦点动物法分别对白头叶猴栖息环境进行了观察 ,并对栖息环境的植物多样性进行了统计分析。结果表明 ,白头叶猴栖息地可分为山脚、山腰、山顶和山弄平地 4部分 ,各部分优势种植物不同 ,白头叶猴栖息地的Shannon Venner多样性指数为 6 1 52 ,均匀度为 0 8439,白头叶猴对石山山脚、山腰、山顶和山弄平地的利用率分布为 66 45±5 65% ,2 1 1 5± 5 49% ,1 2 78± 6 8%和 0。在山脚主要是休息和觅食 ,在山腰主要是移动 ,在山顶主要是冬季晒太阳。因此 。

The quadrat method and animal focus sampling were used to study the botanical diversity in the karst habitat and habitat selection by white headed leaf monkey. According to the geology and vegetation, the karst habitat was divided into four parts which were the top, the middle, the bottom and flat land inside hills. These four parts had their own dominant species of the plant and the Shannon Venner diversity index and the evenness index were 6 152 and 0 843 9 respectively. White headed leaf monkey selectively used three parts of the hills with 66 45±5 65% on bottom, 21 15±5 49% on middle, 12 78±6 8% on top. White headed leaf monkey used the bottom mainly for rest and feeding, the middle mainly for moving and the top for sun bathing in winter.Therefore, it is significant to protect the karst hill habitat as a whole.
