摘 要:
根据多次科考调查等有关资料图件，对三江源地区的物种多样性、生态系统的结构和功能以及人类干扰因素等进行了分析和研究，利用GIS做出三江源地区一系列的珍稀濒危物种和高原特有种分布图、生态系统服务功能价值分布图以及人为干扰强度分布图等，并按层次分析法对三江源生物多样性保护优先地区进行了分析；优先性评估结果将对三江源地区生物多样性保护、生态系统管理和进一步规划提供参考和理论依据．[著者文摘]

Abstract:
Data of species diversity, structure and function of ecosystem and human disturbance on the basis of investigation are used to determine priority areas for biodiversity conservation in Sanjiangyuan Region. By means of GIS, we produce a series of distribution maps of rare and endangered species, special species only distributed in qinghai tibet plateau, the value of ecosystem services and human disturbance degrees, Then, according to Analytic Hierarchy Process a map of priority areas for biodiversity conservation is produced by the overlay of above maps. A biodiversity information system is established in Sanjiangyuan Region based on GIS. The result from assessing priorities in Sanjiangyuan Region by GIS will be useful for biodiversity conservation, ecosystem management and further laying out.[著者文摘]
