摘　　要：研究了面向山地生物多样性保护的资源本体空间分析问题;建立了基于Mereotopology与定位理论的山地多层生物资源本体模型,并在此基础上完成了数字峨眉资源环境动态监测系统。实验证明,该系统不仅存储了峨眉山自然保护区内濒危物种的分布、植被、气候等丰富的资源信息,而且通过空间分析技术,揭示了保护对象与生境的存在状态、破碎程度和变化趋势之间的内在关系。本研究为本体论与山地生物多样性保护工作相结合探索了一条新的途径。The use of spatial analysis in mountain biodiversity conservations as a new research tool had grown tremendously over past year. This paper proposed a strategy called multi-layers ontologies which based on Mereotopology and location theory. This strategy could not only store ＆ maintain biodiversity resource efficiently, but also could qualitative spaiial reasoning of mountain resource in dynamic GIS. A case study in this application domain of EMEI mountain biodiversity conservations involving was examined closely.
