江西芙蓉山自然保护区野生种子植物区系分析

Floristic Analysis of Wild Seed Plants in Furongshan Nature Reserve, Jiangxi Province

  • 摘要: 【目的】调查掌握江西芙蓉山自然保护区野生植物本底资源,有利于加强保护区植物资源保护与合理利用。【方法】通过样方、样线法系统开展了保护区野生植物资源调查,分析了保护区野生种子植物区系多样性和主要特点。【结果】1)保护区野生种子植物共有153科538属1073种;其科的优势现象明显,以禾本科(Gramineae)、菊科(Compositae)、蔷薇科(Rosaceae)和蝶形花科(Papilionaceae)为优势科;属的组成相对分散,寡种属和单种属占总属数的91.45%。2)保护区153科野生种子植物可划分为11个分布区类型,538属可划分为14个分布区类型。【结论】保护区野生种子植物区系特点:1)种类丰富。野生种子植物种类单位面积密度高于周边地区的井冈山、武夷山、阳际峰、马头山、铜钹山、闽江源等国家级自然保护区(国家公园)。2)区系成分复杂多样。从分布区类型看,在科、属的水平上分别占吴征镒等所划分的15种分布区类型的66.67%和93.33%。3)与世界地区联系广泛。保护区野生种子植物是武夷山区系的重要组成部分,与世界多地区存在交流联系,尤与热带亚洲的渊源较深。4)区系热带性质较为明显。保护区热带科、属与温带科、属数量之比(R/T)分别为1.94和1.02。

     

    Abstract: 【Objectives】 To research and understand the wild plant background resources of Furongshan Nature Reserve in Jiangxi Province, which is conducive to strengthening the conservation and responsible use of plant resources in the reserve. 【Methods】 The quadrat and transect methods were used to assess the reserve’s wild plant resources and examine the floristic diversity and key traits of the reserve’s wild seed plants. 【Results】 1) There were 153 families, 538 genera, and 1073 species of wild seed plants in the reserve. The dominant family was Gramineae, Compositae, Rosaceae, and Papilionaceae. 91.45% of the total number of genera were oligonecies and monecies, indicating a relatively distributed genera composition. 2) 153 families of wild seed plants in the reserve could be divided into 11 distribution types, and 538 genera could be divided into 14 distribution types. 【Conclusion】 The floristic characteristics of wild seed plants in the reserve were as follows: 1) The seed plant species were abundant. The density of wild seed plant species per unit area was higher than that in the surrounding areas, including Jinggang Mountain, Wuyi Mountain, Yangji Peak, Matou Mountain, Tongbo Mountain, Minjiangyuan and other national nature reserves (National Parks). 2) The floristic compositions were complex and diverse. In terms of distribution types, they accounted for 66.67% and 93.33% of the 15 distribution types classified by Wu Zhengyi et al at the family and genus levels, respectively. 3) Extensive contacts with the world. The wild seed plants in the reserve were an important part of the Wuyi Mountain flora, and there were close connections with many regions in the world, especially tropical Asia. 4) The flora of wild seed plant species was tropical. The ratio (R/T) of tropical families and genera to temperate families and genera was 1.94 and 1.02, respectively.
