| 摘要: |
| 基于广州从化江埔地区的5个群落类型9个400 m2的样地数据，对该地区风水林的植物群落结构及其物种多样性特征进行了初步研究。结果显示：9个风水林群落样方中，共统计有维管植物96种，隶属于48科。群落类型主要有荷木林、藜蒴林、中华锥林、黄桐林和黄樟林，乔木层常见树种为荷木(Schima superba)、藜蒴(Castanopsis fissa)、中华锥(Castanopsis chinensis)、黄桐(Endospermum chinense)、黄樟(Cinnamomum parthenoxylon)等；灌草层以罗伞树(Ardisia quinquegona)、九节(Psychotria asiatica)、疏花卫矛(Euonymus laxiflorus)、华山姜(Alpinia chinensis)、半边旗(Pteris semipinnata)等植物为优势种。乔木层多样性指数从大到小依次为荷木林＞中华锥林＞黄桐林＞黄樟林＞藜蒴林，灌草层多样性指数由大到小依次为中华锥林＞黄桐林＞荷木林＞黄樟林＞藜蒴林。藜蒴林群落乔木层和灌草层种类较单一，生物多样性较低。 |

| Abstract: |
| Structure and biodiversity of the Geomantic forest in Jiangpu, Conghua, Guangzhou, have been investigated and researched with the sample survey and statistics methods of ecology. The results showed that there were 96 vascular plant species, belonging to 48 families in the 9 Geomantic forests. Five types of forest community, including Schima superba forest, Castanopsis fissa forest, Castanopsis chinensis forest, Endospermum chinense forest and Cinnamomum parthenoxylon forest, were recorded. The dominant species in tree layer were S. superba, Castanopsis fissa, Castanopsis chinensis, E. chinense, and Cinnamomum parthenoxylon . The shrub and herb layer dominant species mainly included Ardisia quinquegona, Psychotria asiatica, Euonymus laxiflorus, Alpinia chinensis, and Pteris semipinnata. The biodiversity indexes of these five communities were different and they were ranked in a descending order of tree layer as follows: S. superba forest > Castanopsis chinensis forest > E. chinense forest > Cinnamomum parthenoxylon forest > Castanopsis fissa forest; the shrub layer were ranked as: Castanopsis chinensis forest > E. chinense forest > S. superba forest > Cinnamomum parthenoxylon forest > Castanopsis fissa forest. |
