摘要

通过样方调查对东莞清溪杨梅坑风水林群落特征进行研究。结果表明:在面积1200m2样方中,杨梅坑风水林共有维管植物61种,隶属36科55属,以茜草科、桃金娘科、樟科、大戟科占优势;植物属的分布区类型以热带亚热带成分占优势;乔木层优势种为龙眼、肉实树、假苹婆、华润楠和臀果木等;灌木层优势种为假苹婆、蒲桃、罗伞树、牛眼马钱、穗花轴榈;草本层优势种为假蒌、蔓生莠竹、土麦冬和弓果黍,层间植物以藤本为主。整个群落年龄结构为增长种群;灌木层多样性指数和丰富度指数最高,乔木层其次,草木层最低;乔木层均匀度指数最高,灌木层其次,草本层最低。
        The character of fengshui woods was studied with the sample in Yangmeikeng of QingxiTown,Dongguan.
