| Abstract: |
| Statistical analysis was performed on plant functional traits (life type, ecological group, leaf texture, inflorescence type, fruit type, and seed dispersal method) of Lijiang River bank. The results showed that there were 37 species of tree, 63 species of shrub, 6 species of subshrub, 15 species of vine and 182 species of herb. There were 201 species of mesophytes, 55 species of hygrophytes, 38 species of semi-hygrophytes and 9 species of amphibians. There were 122 grass leaves, 121 paper leaves, 53 leathery leaves, 4 fleshy leaves and 3 membranous leaves. There were 62 kinds of racemes, 56 kinds of panicles, 54 kinds of cymes and 37 kinds of head inflorescences in the inflorescence types, but there were only 6 species of corymb, cymes and spadix. There was only one kind of the cyme, the compound corymb and the compound dichotomous cyme. There were 66 species of capsule, 53 species of achene, 41 species of drupe, and 28 species of caryopsis, but there were only 8, 7, 5, 3, 2 and 1 species of cellular fruit, angular fruit, samara fruit, divided fruit, citrus fruit and pear fruit respectively. There were 111 species of animal dispersal,83 species of wind dispersal, 58 species of water dispersal and 51 species of autogenous. |
