摘要： 自然遗产地边界界定对于遗产地保护和管理具有重要的意义。已有的遗产地边界界定方法多基于先验知识和专家经验，具有一定的主观性，精度也有待进一步验证。以卫星遥感影像为基础数据，提出层次分析法（Analytic Hierarchy Process, AHP）和GIS结合的自然遗产地边界界定方法，并将其用于四川卧龙自然保护区边界确定。首先利用AHP分析并构建自然遗产地边界影响因子等级体系，然后基于GIS分析建模，通过数字化得到卧龙自然保护区的边界。与已公开的相关资料相比，该方法划定的保护区面积和边界更加科学、客观、精确，为珍稀动物大熊猫栖息地提供了明确的自然边界，而且突出了人与保护区相互关系及保护区的自然和生态保护价值。 关键词： 自然遗产;  边界划分;  层次分析法;  GIS;  卧龙自然保护区     Abstract: Boundary delimitation of natural heritage is very important for its protection and management. The existing methods for boundary delimitation generally rely on the prior knowledge and expert experience, and their results are not accurate enough. To better determine the boundary of natural heritage, a new method was proposed in this study. With the support of remote sensing images and GIS (Geographic Information System) technique, Wolong National Nature Reserve was chosen to be the research object to map its scientific and reasonable boundaries. Firstly, AHP (Analytic Hierarchy Process) was applied to analyze and build the hierarchy system of boundary influence factors, and then with the support of GIS model builder, the reconstruction model of giant panda habitat was established, finally the boundaries of Wolong Natural Reserve were digitized with GIS modeling analysis. Compared with the published documentations, the area extracted by the proposed method is more scientific, objective and accurate. Furthermore, the boundary delimitation method proposed in this paper explores the influence of ecological and humanistic factors on natural heritage and provides a clearer boundary for the habitat of giant panda, which also highlights the relationship between humans and nature reserve.
