摘　　要：本文通过对河西走廊地区明长城沿线种子植物调查,共统计到种子植物26科79属107种,其中裸子植物1科1属1种;被子植物25科78属106种。单种属的科共12个,超过10属的科3个,其总属数占调查总属数的45.6%,种数占调查总种数的51.4%,以藜科最多,共13属21种。科的区系分布类型共4个正型和3个变型。属的区系分布类型共12个正型和9个变型,中国特有属1个,即菊科的河西菊属(Hexinia)。调查区域的植物种类相对单一;地理成分比较单一,以地中海地区、西亚至中亚分布型和北温带成分为主;发现珍惜濒危植物4种,一级保护植物1种,其余均属二级保护。这些结论为利用植物因素保护长城选择适宜的植被类群和代表性物种提供了一定的理论依据。A Survey of the seed plants along the Ming dynasty＇s the Great Wall in the Hexi Region has been carried out. Of the 107 species found in this survey, which belong to 79 genera and 26 families, there are 1 species of the Gymnosperm and 106 species of the Angiosperm, The Gymnosperm covers 1 genus and 1 family; meanwhile, 106 genera and 25 families are included in Angiosperm. Among the 26 families, 12 families have single genus and specie, 3 families are represented by at least 10 genera and account for 45.6% of the total genera and 51.4% of the total species. Chenopodiaceae is the largest family of 13 genera and 21 species. There are 4 areal types and 3 subtypes in the family-level flora, and 12 areal-types and 9 subtypes in the genus level. 1 genus, Hexinia of Compositae, is unique to China. This area has simple geographical elements and fewer plant species, dominant in the Mediterranean area, the area from Western Asia to Central Asia, and the North Temperate Zone. There are g rare and endangered, and 1 species under state protection. The others belong to the second-class state protection plants. These conclusions provide both theoretical and practical evidence for protecting the plants along the Great Wall.
