摘　　要：The development and protection of Shangri-La wetlands in southwestern Yunnan Province is of great significance for the protection of regional biodiversity, ecotourism and regional development. To specify the functions of Shangri-La wetlands, with the help of Analytic Hierarchy Process (AHP), 7 typical wetlands in Shangri-La (Bita Lake Wetland, Napa Lake Wetland, Shudu Lake Wetland, Dazhongdian Wetland, Xiaozhongdian Wetland, Dahei Lake Wetland, Jinsha River Wetland) were selected for the quantitative analysis of 20 indexes in 3 comprehensive assessment layers (service functions, protective functions and production functions). The results showed that Shangri-La wetlands followed the below sequence in function: Bita Lake Wetland (0.811 4), Shudu Lake Wetland (0.739 3), Napa Lake Wetland (0.695 3), Dahei Lake Wetland (0.659 5), Jinsha River Wetland (0.614 3), Dazhongdian Wetland (0.520 4) and Xiaozhongdian Wetland (0.505 2). As single indexes of those wetlands were compared, it was found that values of certain indexes varied greatly, and value differences among 5 of 20 indexes even reached more than 100%, among which that of water supply capacity and tourism recreational value (164.60%) remained the highest, then water supplementation capacity (121.17%) and habitat stability (109.05%), and others varied between 5.58%-91.10%. The assessment results were similar to actual conditions, thus such a method was proved scientific and practical.滇西北香格里拉湿地的开发与保护对区域生物多样性保护、生态旅游及区域发展具有重要意义。为准确认识香格里拉湿地功能,采用层次分析法,选取香格里拉7块典型湿地(碧塔海湿地、纳帕海湿地、属都湖湿地、大中甸湿地、小中甸湿地、大黑海湿地、金沙江湿地)进行3个综合评价层(服务功能、保护功能、生产功能)、20个指标评价的定量评价。结果表明,香格里拉典型湿地功能强弱排序为碧塔海湿地(0.8114)、属都湖湿地(0.7393)、纳帕海湿地(0.6953)、大黑海湿地(0.6595)、金沙江湿地(0.6143)、大中甸湿地(0.5204)、小中甸湿地(0.5052)。从单一指标比较来看,7块湿地某些指标所得的分值差异较大。20项指标中有5项分值大小差异达到100%以上,最高的是供水能力和旅游休闲价值(164.60%),其次为补水能力(121.17%)和生境稳定性(109.05%),其余各项为5.58%～91.10%。从研究结果可知,采用层次分析法得到的评价结果逼近实际状况,表明该方法具有相当的科学性与实用性。
