长臂猿是世界上最濒危的灵长类动物之一。唯一幸存的种群生活在中越边境的喀斯特森林地带。在本研究中，我们利用高分辨率卫星图像对最后种群周围区域的长臂猿栖息地质量进行了评估，并预测了潜在的长臂猿栖息地。然后，我们使用Vortex来模拟种群对栖息地承载能力变化的反应。结果表明，长臂猿种群数量正在接近其栖息地的承载能力，承载能力对种群数量的变化具有重要影响。两个潜在的栖息地位于森林中，通过位于地下河上方的狭窄森林走廊与现有栖息地相连。根据研究结果，建议：(1)在现有长臂猿栖息地内禁止农牧活动；(2)扩大越南白鱀豚保护区，以保护越南潜在的白鱀豚栖息地；(3)保护连接现有栖息地和潜在栖息地的森林廊道；(4)恢复目前缺乏重要食物物种的森林，以支持长臂猿种群和范围的扩大。该研究不仅为维持现有长臂猿种群数量提供了重要的见解，也为越南和中国地方政府在研究地点规划栖息地恢复提供了建议。(C) 2013 Elsevier Ltd.版权所有。
The cao vit gibbon (Nomascus nasutus) is among the most endangered primates in the world. The only surviving population lives in a karst forest patch along the China-Vietnam border. In this study, we used high-resolution satellite images to evaluate the habitat quality of the gibbon in the area immediately surrounding the last population and predict the potential gibbon habitat. We then used Vortex to simulate population responses to changes in the habitat's carrying capacity. Our results showed the gibbon population is approaching the carrying capacity of their current habitat, and carrying capacity has a significant impact on population changes. Two potential habitats were located in a forest connected to the current habitat by a narrow forest corridor, situated above an underground river. Based on the results, we recommend: (1) prohibiting agriculture and grazing activities within the current gibbon habitat; (2) expanding the Cao Vit Gibbon Conservation Area in order to protect potential cao vit habitats in Vietnam; (3) protecting forest corridor that connect the current cao vit habitat to potential habitats; and (4) rehabilitating the forests currently depauperate of important food species in order to support the expansion of both the gibbon population and the range. This research both provides important insight into sustaining the current gibbon population as well as suggestions for both Vietnamese and Chinese local governments planning habitat restoration at the study site.
