中文摘要: |
在赤水桫椤国家级自然保护区内对小黄花茶群落进行野外调查,对其伴生维管植物区系特
征和群落物种多样性进行分析,结果表明:(1)伴生维管植物共148 种,隶属于71 科116 属。其中蕨类
植物16 科19 属21 种,裸子植物2 科2 属2 种,被子植物53 科95 属125 种,占保护区科、属、种的百
分比分别为35.32%、13.23%、6.98%。(2)对种子植物的科、属进行分级比较发现:中等科占总科比例为
78.18%,少种属和中等属占总属比例分别为36.08%、35.05%。对种子植物科、属进行分布区类型的统计发
现,科、属地理成分以热带分布为主,温带成分占有一定比例,反映了该区从热带向温带过渡的性质。该
物种群落分布范围较小,生境脆弱,部分群落人为干扰严重,就地保护是维持群落稳定的关键措施。 |

We investigated the field of Guizhou Chishui Alsophila National Nature Reserve Administration,
and analyzzed the accompanying vascular flora characteristics. The results showed that,there were 148 species
of vascular plants belonging to 71 familie and 116 genera in the community,in which there were pteridophytes
belonging 16 families,19 genera and 21 species,gumnosperms belonging to 2 families,2 genera and 2 species,
and angiosperms belonging to 53 families,95 genera and 125 species,and the percentages of sanctuary families,
genera and species were 35.32%,13.23%,6.98%respectively. For seed plant's families,genera grading,the
percentage of mesotypic family was 78.18% of the total,oligotypic genus and mesotypic genus was 36.08% and
35.05%. By analying the statistics of seed plant families,genus distribution types,the areal types of families and
genera was dominated of tropical floristic,a certain proportion of temperate elements,this refiected the fioristic
characteristics of transition from tropical to temperate components. Distribution of Camellia luteoflora communities
was small,the habitat was fragile,and human disturbance was serious,situ conservation was the key measure to
maintain community stability. |
