摘　　要：采用样地调查法,对深圳市大鹏新区坪西公路雷公山隧道与迭福山隧道段东侧边坡,采用“挂网喷附客土+类芦种子喷播”的方式进行坡面植被建植20 a后的植物群落进行调查分析。结果表明:坡面植物种类显著增加,由刚喷播时的1种植物增加至48种植物,隶属于30科44属,包括阳性植物26种、阴性植物10种和中性植物12种。边坡植物群落组成趋于复杂,由类芦单一种群,演替发展到以类芦(Neyraudia reynaudiana)为优势种,野牡丹(Melastoma candidum)、盐肤木(Rhus chinensis)、毛棯(Melastoma sanguineum)等其它47种植物为伴生种的复杂植物群落。边坡植物群落结构由单一结构片层发展到4个结构片层,木本植物多样性明显高于草本植物,有利于边坡植被的稳定发展。In this study,the characteristics of Neyraudia reynaudiana community in the slope of Pingxi Highway were compared by the sample plot investigation after 20 years of slope greening.The slope is located on the east side of the highway between Leigongshan Tunnel and Deifushan Tunnel in Dapeng New Area,Shenzhen.In the process of slope greening,the wire mesh was used as the bottom layer,and then sprayed with the soil and the seeds of Neyraudia reynaudiana.The results show that:After 20 years of restoration,the plant species of the slope became more abundant,increasing from 1 species to 48 species,belonging to 30 families and 44 genera.According to ecotypes,the 48 plants could be divided to 26 heliophyte species,10 sciophyte species,and 12 neutral plants.The plant species composition of the slope became more complex.The plant community had developed from a single species community of Neyraudia reynaudiana to a complex plant community which included Neyraudia reynaudiana as dominant species,other 47 natural regenerated plants were associated species,such as Melastoma candidum,Rhus chinensis,Melastoma sanguineum,etc.The plant community of the slope changed from a single layer structure to four layer structure.The diversity of woody plants was significantly higher than that of herbaceous plants,so it was conducive to the stable development of slope vegetation.
