摘  要:
本文选择贵阳市环城高速公路南环线、清黄高速公路及其厦蓉高速公路贵州路段边坡的11个人工生态修复群落进行样地调查,从植物群落的丰富度、多样性指数、优势度指数、均匀度指数、重要值和生长效果等方面来分析恢复群落的特征,结果表明:采用不同生态修复(喷播)技术及不同边坡类型上恢复的植物群落的丰富度、物种多样性指数、优势度指数和均匀度指数存在一定差异;不同边坡恢复群落的种类组成及生长效果也存在差异,恢复群落的植物种类组成主要以刺槐Robinia pseudoacacia、多花木兰Magnolia multiflora、双荚决明Cassia bicapsularis、车桑子Dodonaea viscosa、黑麦草Lolium perenne等植物为代表,其在群落中形成一定的优势。
