中文摘要：

运用系统分析方法,在资料收集和实地调查的基础上,借助专家咨询系统,构建了云南省竹类优先保护定量评价指标体系和标准。评价体系包括物种濒危系数、遗传损失系数和利用价值系数3个评价系统层和7个评价指标层。利用专家咨询法和层次分析法,定量确定各个系统层和指标层的权重。通过数学模型和计算机程序计算,分别度量了云南省竹类受威胁状况和优先保护序列状况的濒危系数和优先保护系数。评价结果划分为3个保护等级,第一等级,重点保护对象包括巨龙竹、贡山竹、针麻竹等14个种;第二等级,紧急保护对象,包括55个种;第三等级,特殊保护对象,包括86个种,多为方竹属、箭竹属和玉山竹属等小型竹种。本研究结果为云南竹类珍稀种质资源的保护提供了优先保护的参考依据。

英文摘要：

Based on field survey,information collection and experts consultation,the quantitative grading index system and assessment standards for preference conservation of rare and endangered bamboo in Yunnan Province were established,by using the methods and principles of systematical analysis.The quantitative grading index system included endangered coefficient,genetic coefficient,and useful value coefficient.In addition,7 indicators used to evaluate endangered grading and conservation priorities sequence,were also included in 3 subsystems respectively.Furthermore,the weights of 3 subsystem and 10 indicators were given through experts consultation and analytic hierarchy process.The results showed that the number of the first class species was 14,such as Cephalostachyum scandens,Dendrocalamus sinicus,the second class species 55,the third class species 86,most of them are small graceful palm,such as Fargesia,Yushania,Chimonocalamus.Finally,the problems of conservation priorities sequence is discussed to give some suggestions to protect the rare and endangered bamboo in Yunnan Province.
