中文摘要：

江西金盆山自然保护区位于江西省龙南县、全南县与信丰县的交汇处,为武夷山脉与南岭山脉之间的过渡区域,保护区植物种类丰富、区系地理成分复杂。经野外实地调查、查阅相关文献资料,对保护区内种子植物的科、属、种分布区类型进行统计分析。结果表明：（1）金盆山保护区共有野生种子植物161科659属1 474种,其中裸子植物6科7属7种,占江西裸子植物总种数（83种）的8.43%,被子植物155科652属1 467种,占江西被子植物总种数（4 369种）的33.58%。（2）区系分析显示,金盆山保护区内科的分布区类型中热带分布和温带分布分别占总科数（除去世界分布）的64.22%和35.77%,热带分布占优势地位;属的分布区类型中热带分布和温带分布分别占总属数（除去世界分布）的50.95%和47.55%,二者接近平衡;种的分布区类型中热带分布种和温带分布分别占总种数（除去世界分布）的33.98%和37.15%,而且中国特有种419种,占总种比的28.88%。（3）金盆山保护区种子植物具有单种属、寡种属多,植物区系起源古老的特点,其中有寡种属212属,占总属比的32.17%;单种属374属,占总属比的56.75%;其中寡种属所含种数537种,占总种比的36.43%。（4）与邻近6个保护区的植物区系比较表明,金盆山保护区与武夷山脉的联系较南岭山脉更近,而且金盆山保护区表现出比邻近的阳际峰等武夷山脉地区热带性质更明显。

英文摘要：

Jinpenshan nature reserve is located at the junction of Longnan County, Nanquan County and Xinfeng County, Jiangxi Province. It is the transition zone between Wuyi Mountains and Nanling Mountains. The nature reserve possesses a variety of species and complex geographical floristic elements. Based on field studies and relevant scientific literatures, this study has statistics and analysis the families, genera and species in Jinpenshan. Results showed： （1） 1 474 species of wild seed plants, distributed in 659 genera of 161 families are found in Jinpenshan. Among them, there are 7 gymnosperm species belonging to 7 genera of 6 families, accounting for 8.43% of total gymnosperm species in Jiangxi （83）. Floristic analysis showed, there are 1 467 angiosperm species belonging to 652 genera of 155 families, accounting for 33.58% of total angiosperm species in Jiangxi （4 369）. （2） The families of tropical and temperate distribution patterns make ups 64.22% and 35.77% of the total family number （removal Cosmopolitan, the same below）, respectively. Tropical distribution is in the dominant position. While at genus level, the tropical and temperate distribution patterns make up 50.95% and 47.55%, respectively. They are nearly equal. At species level,the tropical and temperate distribution pattern makes up 33.98% and 37.15%, respectively. While 419 species endemic to China,accounting for 28.88% of total species in Jinpenshan. （3） The flora possess lots of monotypic and oligotypic genera, with an ancient origin. There are 212 genera of oligotypic genera, accounting for 32.17% of the total, 374 genera of monotypic genera, accounting for 56.75% of the total and 537 genera of minor genera, accounting for 36.43% of the total. （4） Compared with the nearby 6 plant floras, there is a closer relationship between Jinpenshan and Wuyi montains than that of Nanling mountains. More tropical elements was observed in Jinpenshen than that of Yangbiaofeng of Wuyi mountains.
