摘　　要：对叶尔羌河流植物区系、植物资源的多样性及濒危等级的评估,对维持地区生态平衡、保护和发掘利用生物资源具有重要意义。本研究采用查阅标本、阅读文献书籍以及野外调查等方法,对叶尔羌河流种子植物资源的多样性、植物区系特点以及濒危等级进行了研究。主要结果如下:叶尔羌河流的种子植物共有56科266属759种,其中裸子植物有3科3属8种,而被子植物共有53科263属751种。菊科、禾本科、豆科、十字花科、莎草科、藜科、石竹科、毛茛科及唇形科植物资源丰富,占该区域植物类群68.25%。该区域植物区系中温带和亚洲植物区系成分占得比例较高以外,还有热带区域的成分。叶尔羌河流的药用植物共有44科104属222种,濒危种子植物有22科32属41种。因此,在该区域建立种子植物资源库及自然保护区来加强濒危物种的保护措施和力度是非常必要的。The assessment of the flora,diversity of plant resources,and endangerment level in the Yarkand River watershed is important for maintaining the ecological balance of the region as well as protecting and utilizing biological resources.In this study,the diversity,floral characteristics,and endangerment level of seed plant resources in this region were studied using methods of botanical resource science,namely,review of specimens,literature,books,and field survey.The main results were as follows:there were 759 species of seed plants from 56 families and 266 genera in the Yarkand River watershed;among them,there were eight species of gymnosperms from three families and three genera and 750 species of angiosperms from 53 families and 263 genera,with rich resources of Asteraceae,Gramineae,Leguminosae,Cruciferae,Salicaceae,Amaranthaceae,Staphylinidae,Ranunculaceae,and Labiatae,accounting for 68.86%of the plant taxa in the region.The flora of the region had a high proportion of temperate and Asian floral components in addition to tropical components.There were 222 species of medicinal plants from 44 families and 104 genera and 41 species of endangered seed plants from 22 families and 32 genera in the Yarkand River regions.Therefore,it is necessary to establish seed plant resource banks and nature reserves in the Yarkand River watershed to strengthen conservation measures for endangered species.
