井冈山稀有濒危植物区系探讨

APPROCH TO THE FLORA OF THE RARE AND ENDANGERED PLANTS IN JINGGANG MOUNTAIN

  • 摘要: 本文分析了井冈山稀有濒危植物39个种的地理分布和35个属的分布区类型及其区系特征,并认为:①稀有濒危植物的古老成份,反映了井冈山自侏罗纪以来地史与气候比较稳定,植物区系区的,演化具有一定的连续性;泥盆纪至侏罗纪可能是井冈山植物区系发生的重要时期。②稀有濒危植物的区系特点是,现代植物区系的种、属成份与华南联系紧密,与华东次之;区系的起源与古热带区系有重要关系。③井冈山特有种的形成可能是生态分异成因多于历史成因,并且温带性物种在井冈山的生态分异比热带性物种更趋强烈。

     

    Abstract: This paper mainly analyses the distribution types of the 35 genera of rare and endangered plants and their geographic distribution of 39 species (including varieties) as well as the flora characteristics in Jinggang Mountain. On the basis of this analysis, some important significances of the rare and endangered plants are discussed as follows: ① The ancient members of the rare and endangered plants show that the geological history and the climate in Jinggang Mountain were relative stability after Jurassic and the flora evolution surely continued. However, it was possible for the flora in Jinggang Mountain to occur from Devonian to Jurassic. ② The analysis results show that the plant flora in Jinggang Mountain had close associates origination with ancienty tropic, perhaps it had more relations with southern China than with eastern China, but few associations with western China. ③ As the evolution causes of endemic plants which only distribute in Jinggang Mountain, the ecologic factors can play a more important role than the history causes. Moreover, temperate plant's ecologic evolution was
