【摘要】 通过野外实地考察、室内标本查阅鉴定，结合相关文献资料查阅，对贵州省毕节市杜鹃花属(Rhododendron)植物种类、分布与生境及其资源利用情况进行调查统计、归类和分析。结果表明：毕节市分布的杜鹃花属植物多样性丰富，有48种，隶属6亚属，8组。垂直分布范围在500～2900 m,多数杜鹃花属植物生长于山坡灌木林中，少数生长于岩石缝隙、山脚或河边灌丛中。毕节市杜鹃花属植物观赏资源丰富，很多种类具有药用价值，开发潜力大，可作进一步开发利用与深入研究。百里杜鹃(Baili Rhododendron)、树枫杜鹃(Rhododendron changii)等种类资源量少，分布狭窄，甚至为毕节市特有，具有重要的保护价值。更多还原

【Abstract】 Here the field investigation, laboratory specimen review and identification were made to classify the species, distribution, habitat, and resource utilization of Rhododendron in Bijie City, Guizhou Province, China. The results showed that there was the rich diversity of Rhododendrons in the study area, particularly with 48 species belonged to six subgenera and eight groups. The vertical distribution was in the range of 500-2900m. Most Rhododendron plants grew in the shrub on the hillside. Only a few was found in the crevices under the rocks at the foot of the mountain or in the thickets along the river. Therefore, Bijie City is rich in the ornamental resources of Rhododendrons, many of which shared the medicinal value and great potential to the further development and utilization in the future. Some species presented the relatively small amount of resource and narrow distribution, such as R. bailiense, and R. changli, parts of which can be found only in the Bijie City, indicating the most important conservation value.更多还原
