摘要
210国道道路、地形、植被等是羚牛东西扩散的限制因素,流动车辆、采集、旅游和商业服务等沿210国道发生的人为活动是羚牛扩散的威胁因素.在诸多威胁因素中,流动车辆对羚牛扩散的影响是第一位的,每日13:00—19:00时的影响为最大,19:00—22:00时的次之,04:00—07:00时最小,羚牛的扩散成功率仅为8.53%.采集活动的干扰次之,其次是旅游活动和商业性服务活动的干扰.进行边界调整、促进国道两侧植被恢复、建立210国道生态桥、严格车辆、商户和旅游管理,是消除影响的基本措施.
In all of the influence factors, the road G210, topography and vegetation are restrict factors. The floating vehicle, harvest, tourism and the service trades of human activities are threat factors along the road G210. In all of the threat factors of human activities, the serious disturbance is the floating vehicle, the second is harvest, then is tourism and service trades. Readjusting reserve boundary, advancing restoration of the vegetation on both side the highway, establishing bio- bridge above the road, strengthening management to the floating vehicle, businessman, and tourist, it is the primary management strategy to remove the influence of road G210 on the diffusion by golden takin between east and west within Niubeiliang national nature reserve.
