摘　　要：为加强对伊犁河谷地区公路路域野生植物的保育和利用,采用踏查法对研究区内多条典型公路路域范围内的野生植物进行了调查统计和科属及区系特征分析。结果表明:研究区内共发现野生种子植物63种,隶属于58属25科,以菊科最多,其次为唇形科、藜科、豆科、禾本科等,优势科明显;新疆特有植物占科属种的比例较大,特有植物科占总科数的76%,以一年生或多年生草本为主,其中大量的特有种、珍贵种和孑遗种在野生植物资源的研究和保护方面价值较大;属的区系具有较高的多元性,以北温带分布及其变型为主,温带分布性质占绝对优势;共有21科44种野生种子植物具有良好的观赏价值,以多年生菊科、唇形科、豆科的草本分布相对较多,结合公路节点特点提出植物景观配置模式,为该区域公路路域绿化造景提供参考。In order to strengthen the conservation and utilization of wild plants in highway road areas in the Ili Valley,the inspection method is applied to gather related statistics and deliver an analysis of family,genus and floristic characteristics about the wild plants in the research area.The results show that there are in total 63 species of wild seed plants which belong to 58 genera and 25 families.The dominant families are quite obvious:Compositae is the most common,followed by Labiatae,Chenopodiaceae,Leguminosae,Gramineae.The endemic plants in Xinjiang,most of which are annual or perennial herbs,accounting for a large proportion of families(about 76%),having great value in the research and protection of wild plant resources.The fauna of genus has high diversity,while the north temperate distribution and its variation are dominant in the north-the temperate distribution takes absolute advantage.A total of 44 species of wild seed plants belonging to 21 families have good ornamental value.Theeperennia1l Compositae,,Labiatae andLeguminosae haveerelativelyylargeherb distribution.Combined with the characteristics of highway nodes,the plant landscape configuration mode is proposed,providing reference for the greening and landscaping of highway road areas in this region.
