摘　　要：在沪蓉西高速公路宜昌—长阳段引种植物观测的基础上,选择初期生长力、抗逆性、生长势3个指标评价19种木本植物、8种草本植物的表现,并以隶属度值为基础进行3个指标的分类排序与等级划分及综合评价。结果表明:供试植物中以马棘表现最优,苦刺、波叶山蚂蟥、狗牙根、苦楝、刺槐、截叶胡枝子、荆条、百喜草表现良好,高羊茅、弯叶画眉草、柘树、盐肤木、坡柳、决明、冻绿、臭椿表现中等,百脉根、枫杨、鸡眼草、乌桕、假俭草、白三叶等表现较差,马尾松表现最差;木豆、山毛豆、猪屎豆第1年生长速度十分迅速,但抗寒性差,持续能力差。Three indices including early growth ability,stress resistance,growth potential were used to evaluate 19 tree plants and 8 herbaceous plants based upon introduce and observation of the experiment plants in Yichang—Changyang section of Shanghai—Chengdu freeway in Hubei Province.Value of subjection was calculated based on classifying analysis,ranking series and comprehensive assessment.Results show that the Indigofera pseudotinctoria have the best performance,Solanum deflexicarpum,Desmodium sinuatum,Cynodon dactylon,Melia azedarach,Robinia pseudoacacia,Lespedeza cunecta,Vitex negundo,Paspalum notatum rank the second,Festuca arundinacea,Eragrostis curvula,Cudrania tricuspidata,Rhus chinensis,Dodonaea viscosa,Senna obtusifolia,Rhamnus utilis,Ailanthus altissima rank the third,Lotus corniculatus,Pterocarya kunth,Kummerrowia stipulacea,Sapiu sebiferum,Eremochloa ophiuroides,Trifolium repens rank the forth,Pinus massoniana rank the poorest;Cajanus cajan,Tephrosia candid and Crotaria assamica grew fast in the seeding year,but nearly all failed survive the winter.
