【摘要】 该文以遥感和地理信息系统作为信息获取与处理工具,并利用2000年TM遥感影像为基础信息源,分析玛曲国家级生态功能保护区特征。根据整体性、发生统一性、生态功能相对一致性、主导性和方便管理等分区原则,依照研究区生态服务功能的不同以及生态系统受胁迫程度的差异,运用自上而下的序列划分法对其进行了两级分区,得出了4个一级区6个二级区的分类系统,针对区域的特征和主要生态问题,提出相应的建设目标和措施。

【Abstract】 Maqu National Ecological Function Reserve is located in the north-east of the Tebetan Plateau,south of Gansu Province.In this paper,remote sensing(RS) and geographical information system(GIS) are used as tools for obtaining and processing information.Based on the basic information source,the TM image of 2000 and the characteristics of the research region are analyzed.According to the integrality,development-unified,relatively-united ecological function,mainly-decided and convenient administration rules etc., and on the basis of the differences of the ecological serving functions as well as the threatened extent to the ecosystem ,this paper uses the from-top-to-bottom sequence division method to divide the Maqu National Ecological Function Reserve into 2-grade regions.Finally a classification system of 4 first-level regions and 6 second-level regions comes into being.The characteristics,main ecological problems,necessary goals and measures in each divided region are also analyzed.
