摘　　要：通过十几年大量的实地野外调查、相关文献资料查阅以及标本的考证等手段和方法,初步探究了贵州省凤仙花属植物的种类、分布特点以及区系特征。结果表明:1)贵州省自然分布的凤仙花属植物有69种(含1变种),它们在地理分布上具有明显的狭域性和特有性,且南部明显多于北部;2)贵州省凤仙花属植物区系在地理成分上以地区特有、热带亚洲分布和温带亚洲分布类型为主,其中,中国特有种62种(占89.86%),西南特有种10种(占14.49%),贵州特有种10种(占14.49%);3)贵州省凤仙花属植物兼具原始类群和进化类群,具有从热带向温带过渡的特点,可能是中国凤仙花科植物演化中心的一部分。本文关于贵州省凤仙花属类群的深入调查与区系特征的分析研究,对摸清贵州省凤仙花属种类、地理分布格局及区系成分和特征具有一定的科学意义,也为贵州省的植物多样性研究提供了参考依据。A preliminary investigation of the species, distribution and floristic characteristics of Impatiens in Guizhou Province has been carried out for more than ten years through field investigation, relevant literature review and specimen research. The results obtained are as follows: 1) There are 69 species(including one variety) of Impatiens L. in Guizhou. They are obviously distributed in narrow range with endemism, and grow more in the south of Guizhou than the north;2) In terms of geographical composition, most of the Impatiens plants in Guizhou Province are region-specific and belong to tropical Asia and temperate Asia distribution types. Among them, 62 species are endemic to China(89.86%), 10 endemic to Southwest China(14.49%) and 10 endemic to Guizhou(14.49%);3) Due to their primitive and evolutionary taxa and the characteristics of transition from tropical to temperate zones, the Impatiens plants in Guizhou are probably parts of the evolutionary center of Balsaminaceae in China. This investigation is beneficial to understanding the species, geographical distribution pattern and floristic components and characteristics of Impatiens in Guizhou. It also provides reference for studying plant diversity in this province.
