摘　　要：四川省西部甘孜藏族自治州和凉山彝族自治州地区共有48科90属187种水生维管束植物。植物区系地理成分较复杂,具有较明显温带性质。48科植物可以划分6个分布型和1个变型,世界分布34科,热带分布6科,温带分布8科;90属被划分为10个分布型和6个变型,世界分布35属,热带分布22属,温带分布33属;184种野生种可以归并为14个分布型和2个变型,世界分布14种,热带分布26种,温带分布107种,中国特有分布37种,特有现象明显。水生维管束植物的生态类型多样,有101种挺水植物,31类挺水植物群落;有40种沉水植物,18类沉水植物群落;有16种飘浮植物,6类飘浮植物群落;有27种浮叶植物,8类浮叶植物群落。There are 187 species of aquatic and vascular plants belonging to 90 genera and 48 families in Ganzi Tibetan Autonomous Prefecture and Liangshan Yi Autonomous Prefecture in western Sichuan.The floristic elements of aquatic and vascular plants are very complicated with obvious temperate feature,48 families can be divided into 6 distribution types and 1 variant type.There are 34 families in world distribution type,6 families in tropical one and 8 families in temperate one.90 genera can be classified into 10 distribution types and 6 variant types.There are 35 genera in world distribution type,22 genera in the tropical one and 33 genera in the temperate one.184 wild species can be divided into 14 distribution types and 2 variant types.There are 14 species in the world distribution type,26 species in the tropical one and 107 species in the temperate one.37 species are endemic in China.The ecological types of aquatic and vascular plants can be divided into 101 species of the emergent anchored hydrophytes,40 species of the submerged anchored hydrophytes,16 species of the floating hydrophytes and 27 species of the floating-leaved anchored hydrophytes.The vegetation types of aquatic and vascular plants can be classified into 31 types of the emergent anchored hydrophytes,18 types of the submerged anchored hydrophytes,6 types of the floating hydrophytes,8 types of the floating-leaved anchored hydrophytes.
