| 摘 要： | 对乳源木莲天然林中主要乔木树种种群进行生态位测定，包括生态位宽度、生态位重叠和生态位相似比例。结果表明：乳源木莲天然林中拉氏拷和乳源木莲生态位宽度较大，在群落中处于优势地位。群落中各种群间关系较为复杂，对资源共享的趋势较明显。天然林群落中各物种利用资源相似程度较大，乳源木莲易与生态位宽的树种形成混交林。

| Abstract: | The niche characteristics of the dominant tree species were measured in the natural forestry of Manglietia yuyuanensis community. including niche breadth, niche overlap and niche proportional similarity. The result showed: the niche breadthes of Castanopsis lamontii and Manglietia yuyuanensis were larger and they were the dominant populations. The relations among populations were complex, and the natural resources were shared. The niche proportional similarity was larger, and Manglietia yuyuanensis could be mixed with the greater niche breadth species. |
