研究了广东八宝山森林群落２５个优势种群的生态位特征．以Ｓｈａｎｎｏｎ－Ｗｉｅｎｅｒ指数和相似性比例分别计算了２５个种群的生态位宽度及它们之间所形成的部分种对的生态位重叠。结果表明，八宝山森林群落中生态位宽度最大的种群为红背锥、米锥、硬斗稠以及木荷。生态位宽度的大小与按重要值排列的优势种群顺序基本一致。生态位重叠则与生态位宽度有一定关系，具较宽生态位的２个种群一般都有着较高的生态位重叠值。文章还对生态位特征研究的意义及应用作了简要的说明。
The niche characteristics of 25 dominant species in forest communities of Babaoshan Mountain in Guangdong Province were studied. The niche breadths of 25 populations and the niche overlap of some species pairs formed between them were calculated by Shannon-Wiener index and similarity ratio respectively. The results showed that the populations with the largest niche breadth in Babaoshan forest community were red-backed cone, rice cone, hard-dough and Schima superba. The size of niche breadth is basically consistent with the order of dominant populations arranged according to their importance. Niche overlap has a certain relationship with niche breadth. Two populations with broad niche generally have higher niche overlap. The article also gives a brief description of the significance and application of niche characteristics.
