| 摘 要： | 在春季用样方法对珠江三角洲5个城市32个样点草坪绿地杂草群落进行调查，并分析了不同样地杂草群落的发生规律。调查共发现84种杂草，属30科，68属。其中，水蜈蚣重要值最大，为20．332／6，其次是三点金，为11．369，6；狗牙根、崩大碗、香附子、天胡荽等杂草为珠江三角洲地区草坪绿地恶性杂草，其重要值均大于5．00％。广州市形成以水蜈蚣＋天胡荽＋狗牙根为主的杂草群落；珠海市以三点金＋狗牙根＋水蜈蚣为主；惠州市以水蜈蚣＋狗牙根十三点金为主；中山市以水蜈蚣＋崩大碗＋天胡荽为主；肇庆市以水蜈蚣＋香附子＋狗牙根为主。通过聚类分析可以将32个样点分成5个组。结果表明：在相似管理水平下，地理环境是影响杂草群落结构的最重要因素。
