摘要
通过调查粤东地区两条高速公路内的互通立交区绿地的植物多样性和应用现状,结果表明:在6个1200 m2的样方中有维管植物112种及变种,隶属45科96属,较丰富的种类有禾本科、菊科、大戟科等。绿地的物种多样性不高,各层多样性指数表现为草本层>灌木层>乔木层,绿化形式简单粗陋,养护管理有待加强。建议推广优良乡土植物,促进绿地植物的多样性和生态效益的提高。
The plant diversity and their application status around the greenbelt of interchanges of the two expressway in the east Guangdong were investigated by plot method. A total of 112 vascular plants were recorded in six plots with the area of 1200 m2. They belong to 45 families and 96 genera. The dominant families are Gramineae, Compositae and Euphorbiaceae. The plant diversity of different vertical layers in three types of green-lands was as follows： shrub layer herb layer tree layer. Greening form of the interchanges is simple, humble. It was recommended to increase the application of native plant species, promote the maintenance and management of the green-space and improve the species diversity and ecological benefits of the greenbelt of interchanges.
