【摘要】 云南云龙水库库区共有药用种子植物104种,隶属于56科94属,占该区全部种子植物种的23.3%,优势科为Compositae,Lab iatae,Campanu laceae,Umbelliferae,Ranuncu laceae,Rosaceae,Rub iaceae和Scrophu lariaceae,优势属为Anem one,Artem isia,Carpesium,Conyza和Elsholtzia。该区药用种子植物垂直分布不均匀,在海拔2 070~2 080 m种最多,其次是2 010~2 030 m,再次是2 430~2 440 m。水库完成蓄水后,将53.8%的药用种子植物被永久淹没。研究结果可为库区周边生态环境保护和对该区药用种子植物资源的科学保护和开发利用提供参考。更多还原

【Abstract】 In the area of Yunlong reservoir of Yunnan province,there are 104 species of wild resourcesof medicinal seed plants which belong to 56 families and 94 genera.The percentage of the medicinalseed plants to the total seed plants in the same area is23.3%.The preponderant families of medicinalseed plants are Compositae,Labiatae,Campanulaceae,Umbelliferae,Ranunculaceae,Rosaceae,Ru-biaceae and Scrophulariaceae.The preponderant genera areAnemone,Artemisia,Carpesium,Conyzaand Elsholtzia.The perpendicular distribution of the medicinal seed plants is asymmetrical.The spe-cies number in the altitude of 2 070 ~2 080 m is the maximum,next is the 2 010 ~2 030 m and thethird is the 2430 ~2440 m.After the water-storing of reservoir is fulfilled entirely,53.8% of the wildresources of medicinal seed plants will permanently be submerged.This research may provide a prepar-atory information for the protection of the entironment surrounding the reservoir and for the scientificsafeguard and utilization of the wild resources of medicinal seed plants.更多还原
