| 摘要: |
| 论述云南石林县长湖湖泊湿地范围内湿地植物的植物区系组成及地理成分特点,为保护和利用湿地资源提供科学依据。结果表明:(1)有湿地植物20科47属56种,种类多样性较突出;(2)植物区系统计,广布的科、属、种分别占95%、40.4%、19.6%,湿地植物的广布性突出;(3)科级区系中热带分布占5%,属级区系中热带分布占38.2%、温带分布占21.4%,种级区系中热带分布占32.2%、温带分布占42.8%,属级和种级区系显示亚热带区系的区域性;(4)种级区系中特有分布占5.4%,且为当地特有变种,显示出较高特有性。 |

| Abstract: |
| Composition and geographical element characteristics of wetland plant flora in Changhu Lake were studied in this paper for providing scientific foundation of conservation and utilization of the wetland resources. The results showed that:(1)there were 56 wetland plant species that belong to 47 genera and 20 families in Changhu Lake,which implied Changhu Lake's species diversity was obvious;(2)the percentage of cosmopolitan families,genera and species was 95%,40.4% and 19.6% respectively,which showed most wetland plants of Changhu Lake were cosmopolitan;(3)Tropic and temperate areal-types were the main floristic elements,which showed the subtropic characteristics of the flora;(4)the species flora was relatively high in endemic,as the endemic species accounted for 5.4% of the total. |
