摘　　要：植物区系的研究是认识和保护区域植物的重要手段之一.通过2019年对在建楚姚(楚雄至大姚)高速公路红线外延1 000 m范围的植物资源进行实地调查,在系统地整理出评价区维管束植物名录的基础上,开展该高速公路所在区域沿线的植物种类组成及区系特征的统计分析和研究.结果表明:楚姚高速公路沿线共有种子植物118科384属649种,其中裸子植物2科3属4种,被子植物116科381属645种;种子植物区系中热带性质科、属占优势,其中热带分布50科、166属,分别占总科数、总属数(不含世界分布科)的68.49%、50.15%,显示了该路域具有区系地理成分复杂多样及与热带区系关系密切的特点.在此基础上,提出了楚姚高速路域植物保护和生态重建的相关建议措施.The study on the floristic analysis is one of the most important means of cognizing and protecting plants. In 2019, by the field survey of the plant resource in the extensive range of 1 km of the red line in Chuxiong-Dayao highway, the composition and floristic characteristics of plant along the Chuxiong-Dayao highway were analyzed statistically on the basis of the systematic list of vascular plants.The results showed that 649 vascular species(384 genera, 118 families) were recorded in Chuxiong-Dayao highway, among of them, 4 species(3 genera, 2 families) are gymnosperm and 645 species(381 genera, 116 families) are angiosperm;The tropical families and genera including 166 genera and 50 families predominant in the flora of seed plants which accounted for 68.49% and 50.15%. The above indicated that the geographical composition of flora was complicated in the evaluation zone and various and closedly associated with the tropical flora. And the relevant measures of plant protection and ecological reconstruction of roadside were put forward on the basis of the above result.
