摘　　要：通过对滇西北地区（怒江、丽江、香格里拉等）凤仙花属植物资源进行实地调查,共收集凤仙花属植物20种,并对其地理分布及外部形态进行了分析。结果表明：该地区凤仙花属植物主要分布于海拔1 300-3 600m,多生长在山间路旁、草丛、林下湿地等湿度相对较大的地方;株高在30-70cm;花色有黄色、紫色、白色、粉色等;叶片长度3.8-16.5cm,宽度1.4-5.6cm,叶面积5.53-20.23cm2;种子直径1.08-2.79mm,千粒重0.011-5.900g;并对滇西北凤仙花属植物的园林开发应用提出了相应的意见和建议,以期为今后云南凤仙花属植物资源的保存和开发利用提供一定的基础数据和理论依据。According to the on-the-spot investigation and analysis of Impatiens L.in Northwest Yunnan,such as Nujiang,Lijiang,Xianggelila etc.,20 species were found and their geographical distribution and morphological characters were fatherly analyzed.The results showed that all the species of Impatiens L.mainly distributed in the altitude 1 300-3 600 m,and grew besides the mountain road,grassland,wetland under the forests with high relative humidity;that whose height ranged from 30 cm to 70cm;that whose flower colors were rich,e.g.yellow,purple,white and pink etc;that whose leaf length varied from 3.8cm to 16.5cm,and its width ranged from 1.4cm to 5.6cm;that whose leaf area were from5.53cm2 to 20.23cm2;that whose seed diameter varied from 1.08 mm to 2.79 mm,and thousand seed weight reached from 0.011 g to 5.900g;that some suggestions about landscape applications of all the species of Impatiens L.in Northwest Yunnan were proposed,it laid some certain scientific data and theoretical basis for their resource conservation and exploitation in the future.
