摘　　要：基于云南铜壁关省级自然保护区科学考察数据,从物种组成、地理区系、生活型等方面对保护区菊科植物物种多样性进行了分析。结果表明:保护区菊科植物有76属185种,划分为10个族,其中以旋覆花族、向日葵族、千里光族、菊苣族为主。保护区菊科植物以单种属最多(42属),寡种属次之(26属),多种属第三(8属),但从种一级水平来看,寡种属和多种属种数最多。保护区记录到入侵植物25种,占总种数的13.51%。保护区菊科植物区系在属一级水平上可划分为12个类型1个变型,其中以泛热带分布(14属)和旧世界温带分布(13属)为主,其生活型较为丰富,多年生植物占总种数的73.51%,其中以地面芽植物为主,占总种数的45.40%。建议加强对恶性入侵植物种类的监测研究力度,同时加强对其他菊科植物资源的调查、保护及开发利用研究。Based on the investigation data of Tongbiguan Provincial Nature Reserve in Yunnan Province,the species diversity of Compositae in this Nature Reserve was analyzed in terms of species composition,geographical flora and life forms.The results showed that there are 185 species representing 76 genera of Compositae in the reserve.These can be divided into 10 families,among which the Inula,Helianthus,Senecio and Chicory are the main ones(covering 42 genera),followed by Oligospecies(26 genera),and the third family(8 genera).But from the perspective of the species level,the number of species in Oligospecies was the largest.Invasive plants were also recorded in the protected area,accounting for a total 25 of species observed,accounting for 13.51%of all species.The Asteraceae flora in the reserve can be divided into 12 types and 1 variant at the genus level,among which the Pantropical distribution(14 genera)and the Old World temperate distribution(13 genera).The life forms of Compositae plants in the protected area are relatively rich,and perennial plants account for 73.51%of the total species,of which ground bud plants are the most common species,accounting for 45.4%of the total species.It is recommended to strengthen the monitoring and research of malignant invasive plant species,and at the same time strengthen the investigation,protection,development and utilization of other Compositae plant resources.
