摘要： 通过对定西地区战国秦长城沿线种子植物调查，共统计到种子植物58科242属444种，其中裸子植物2科3属3种；被子植物56科239属441种。单种属的科共15个，超过10属的科5个，其总属数占调查总属数的45.5%，种数占调查总种数的52.4%，以菊科最多，共38属82种。科的区系分布类型共4个正型和4个变型。属的区系分布类型共13个正型和11个变型，中国特有属2个，分布在菊科（Compositae）和伞形科（Umbelliferae）。调查区域的植物种类相对丰富；地理成分比较复杂，以温带成分占优势，以北温带分布型和旧世界温带分布型为主；发现珍稀濒危植物2种。这为保护长城选择适宜的植物类群和代表性物种提供了理论依据。

Abstract: In this study,a survey on seed plants along the Great Wall built in the Warring States Period and the Qin Dynasty in the Dingxi area of Gansu Province was carried out.In the survey 444 plant species in 242 genera and 58 families were found,in which 3 species in 3 genera and 2 families belonged to Gymnosperm,and 441 species in 239 genera and 56 families belonged to Angiosperm.Among the 58 families,there were 15 monotypic genus families and 5 families with more than 10 genera at least,and they accounted for 45.5% and 52.4% of the total surveyed genera and total species respectively.Compositae with 82 species and 38 genera was the richest family.There were 4 areal types and 4 subtypes at family level,and 13 areal types and 11 subtypes at genus level,in which 2 genera belonging to Compositae and Umbelliferae were endemic in China.There were the rich plant species and complex geographical elements in the study area,the flora were dominated by the Old World Temperate and the North Temperate types.Two rare and endangered species with low protection level were found.These conclusions could contribute to the theoretical and practical proofs for protecting the Great Wall with plants.
