| 摘 要： | 在全球变化的大背景下,自然保护区是维持西藏生态环境可持续发展的重要手段.本文以西藏工布自然保护区为例,基于生态足迹模型,计算该保护区2007年有效物质消费量与有效可利用生态生产性土地面积,分析其生态足迹和生态承载力,为宏观指导西藏地区如何处理经济发展与生态环境保护的关系提供科学依据.分析表明:西藏工布自然保护区2007年人均生态足迹为1.5785hm~2,人均生态承栽力为21.2453hm~2,人均生态盈余为19.6668hm~2,盈余比例达92.57%.人均生态足迹中,对耕地的需求最大,其次为化石燃料产地、林地、草地、建筑用地,对于水域的利用缺乏统计数据.工布自然保护区生态承栽力远大于生态足迹,其中以林地为主,体现了当地的生态特色.

| Abstract: | In the context of global change,the eco-environment of the Qinghai-Tibetan Plateau is increasingly affected by a variety of disturbances.It is difficult to maintain sustainable development for some originally vulnerable ecosystems across the region.Therefore,exploring the feasibility of different ecosystem management methods is of great importance to the sustainable development of the area.A nature reserve is one of effective management approaches to maintaining sustainable development of ecosystems in Tibe... |
