摘要
文章对广东韶钢厂内3个功能区绿地的植物多样性进行了调查。在108个10 m×10 m的样方中共记录了园林植物167种,隶属68科122属,以木兰科、桃金娘科、蔷薇科、苏木科、桑科较为丰富。物种多样性分析结果显示,各类绿地物种多样性水平由高到低依次为:生活区>生产区>道路;从群落分层物种多样性平均水平看,多样性指数均表现为乔木层>草本层>灌木层;调查结果揭示了韶钢厂区绿地存在着绿地植物群落结构不稳定、群落类型不够丰富、单一植物物种使用频率太高和外来植物比例过高等问题,笔者就此提出相应的建议。
Plant diversity of three types of green lands in Shaoguan Iron ＆ Steel Group Co., Ltd. （CSG） was surveyed. There were 167 species of vascular plant in 122 genera of 68 families in 108 plots of 10 m × 10 m. The major families more species are Magnoliaceae, Myrtaceae, Rosaceae, Caesalpiniaceae and Moraceae. Extent of plant diversity was followed as the residential areas 〉 the production areas〉 the road areas. The plant diversity of different vertical layers in three types of green-lands was as follows： tree layer〉 herb layer 〉 shrub layer. Garden plant diversity in CSG as often disturbed by the constructive works, the artificial plant communities were relatively simple, individual quantities of less species were more higher, and the composition of exotic plant species was higher. Some suggestions were proposed to improve the Greenland plant diversity of CSG.
