- 摘要:
- 通过野外调查和文献整理,对西藏凤仙花属植物资源的分布、观赏特性和园林应用进行了研究。结果表明:西藏现有凤仙花属植物35种和3变种,其中含1种栽培植物。野生种占到全国凤仙花属植物总种数的13.28%;该属资源丰富度在全国范围内仅次于四川和云南,且均具有较高的观赏价值;其特有性较很高,中国特有种15种,其中包含西藏特有种7种,中国特有的比例达到40.54%,西藏特有也高达21.62%。在对其地理分布和观赏价值分析的基础上,提出了建立资源圃、保护野外生境、合理有序开发和尽快进行新品种培育等保护开发建议。
- Abstract:
- Based on a full-scale and systematic investigation and literature collection,the distribution of impatiens resources in Tibet,ornamental characteristics and landscape application were studied.The results showed that there were 38 species(including varieties) of Impatiens in Tibet,accounting for 13.28% of this genus in China.The richness of Impatiens ranks third following Sichuan and Yunnan Province in China.All species of this genus possessed high ornamental value.Besides,Impatiens had extremely high endemism.15 endemic species distribute nationwide including 7 species that only habitat in Tibet.The endemism proportions of China and Tibet to the world reach to 40.54% and 21.62% respectively.On the basis of the analysis of plant medical and ornamental value,measures like establishing germplasm,protecting habitat,reasonable development and cultivating new varieties should be taken immediately.
