【摘要】 采用层次分析法(AHP)构建优先保护评价指标体系，计算分析岷江上游地区杓兰属植物的濒危值、遗传价值、物种价值、综合评价值，得出杓兰属植物的优先保护等级评价，结合杓兰属植物分布情况，划分不同级别的优先保护区域。结果表明：Ⅰ级优先保护物种有小花杓兰(Cypripedium micranthum)、巴郎山杓兰(C.palangshanense)、四川杓兰(C.sichuanense)共3种；Ⅱ级优先保护物种有华西杓兰(C.farreri)、毛杓兰(C.franchetii)、波密杓兰(C.ludlowii)、对叶杓兰(C.debile)、褐花杓兰(C.smithii)等5种；Ⅲ级优先保护物种有大叶杓兰(C.fasciolatum)、毛瓣杓兰(C.fargesii)、离萼杓兰(C.plectrochilum)、山西杓兰(C.shanxiense)等4种；Ⅳ级优先保护物种有绿花杓兰(C.henryi)、无苞杓兰(C.bardolphianum)、紫点杓兰(C.guttatum)、黄花杓兰(C.flavum)、西藏杓兰(C.tibeticum)等5种。卧龙自然保护区、黄龙寺自然保护区、九寨沟森林公园为Ⅰ级优先保护区域，面积275 280 hm~2(41%);贡杠岭自然保护区、牟尼沟风景名胜区为Ⅱ级优先保护区域，面积172 022 hm~2(26%);卡龙沟自然保护区、达古冰川风景名胜区、米亚罗自然保护区、九顶山自然保护区、草坡自然保护区为Ⅲ级优先保护区域，面积225 155 hm~2(33%)。研究结果为针对性开展杓兰研究和保护工作提供了科技支撑。更多还原

【Abstract】 Species diversity investigation and priority protection evaluation are the basis for the protection of rare and endangered plants. In this paper, the analytic hierarchy process(AHP) was used to build the priority protection evaluation index system. We calculated and analyzed the endangered value, genetic value, species value, comprehensive evaluation value, and the priority protection grade, in combination with the distribution of Cypripedium plants in the upper reaches of Minjiang river, to determine the priority protection areas at various levels. The results showed that the first priority protection species are C. micranthum, C. palangshanense and C. sichuanense. The second priority species are C. farreri, C. franchetii, C. ludlowii, C. debile, C. smithii. The third grade priority protection species are C. fasciolatum, C. fargesii, C. plectrochilum, C. shanxiense, and the fourth priority species are C. henryi, C. bardolphianum, C. guttatum, C. flavum, C. tibeticum. The Wolong Nature Reserve, Huanglong Temple Nature Reserve and Jiuzhaigou Forest Park belong to the class Ⅰ of priority protection areas, with an area of 275 280 hm~2(41%). The Gonggangling Nature Reserve and Munigou Scenic Spot are class Ⅱ of priority protection areas with an area of 172 022 hm~2(26%). The Kalonggou Nature Reserve, Dagu Glacier Scenic Spot, Miyaro Nature Reserve, Jiudingshan Nature Reserve and Caopo Nature Reserve are the priority protection areas of class Ⅲ, with an area of 225 155 hm~2(33%). The results provided scientific supports for special research and conservation of Cypripedium plants in the upper reaches of Minjiang river.更多还原
