| 摘 要： | 在含土沉香的广州市萝岗区风水林（村边次生常绿阔叶林）设样方进行调查,分析其组成和结构特征。在800 m^2样地内有维管植物70种,隶属于39科60属,以热带分布科和属占优势;优势科有茜草科、樟科和大戟科等,群落成层现象明显,可分为乔木层（3个亚层）、灌木层和草本层3个层次,层间植物丰富。乔木层第1亚层木荷重要值最大,黄果厚壳桂次之,该群落命名为木荷＋黄果厚壳桂＋黄杞群落（Schima su-perba＋Cryptocarya concinna＋Engelhardtia roxburghiana Community）。生活型以中、小高位芽为主,叶型以中、小革质单叶为主;种群频度分布规律为A〉B〉C〉E,属于A级的种类占优势;土沉香（Aquilaria sinensis）以小径级为主,只要环境合适,自身具有较强的更新能力;样方内部分植株侧根或树枝遭人为砍伐,树干被砍伤,严重影响植株生长。土沉香是广东省地道药材的＂十大广药＂之一,建议在广州市有野生土沉香生长的植物群落,设立自然保护小区进行保护。
