摘要: 以浙江天童披针叶茴香Illicium lanceolatum-南酸枣Choerospondias axiliaris群落为对象，应用每木调查法、时空互代法和相邻格子法研究分析群落优势种群结构和分布格局。种群结构分析包括胸径级结构和垂直层次结构，空间格局分析包括各种不同垂直层次个体的空间分布格局。5个优势种群总体相对优势度达到74.85%，大小级指数除南酸枣和橄榄槭Acer olivaceum为正值外，披针叶茴香、红楠Machilus thunbergii和华东楠M. leptophylla均为负值，各个种在垂直空间上占据了不同的位置。不同种之间以及同种不同层次之间表现出复杂多样的分布格局，体现出多级复合分布特征，披针叶茴香、华东楠表现为聚集分布，而南酸枣、橄榄槭表现为均匀分布，红楠表现为随机分布。各个物种通过占据不同的水平和垂直空间，在群落中得以共存。表5参23

Abstract: The population structure and spatial distribution patterns of 5 dominant populations in the Illicium lanceolatum-Choerospondias axiliaris community of Tiantong（29°48′N，121°47′E） were investigated by using every-tree measuring method，time specific method for life-table analysis and contiguous grid method. Spatial distribution and spatial association of individuals in different layers of 5 dominant populations were analyzed. The total relative basic area（RBA） of the 5 species was 74.85%. The size distribution index （SDI） of I.lanceolatum，Machilus thunbergii and M. leptophylla was negative and relatively low，except for C. axiliaris and Acer olivaceum which had a positive value. The species occupied different vertical spaces. The spatial distribution varied among intra- and inter-specific cohorts in the different layers and size classes and showed complex multilevel distribution patterns. The I. lanceolatum and M. leptophylla had an aggregated distribution，C. axiliaris and A.olivaceum had an uniform distribution and M. thunbergii had a random distribution. There were differences in spatial associations among intra- and inter-specific cohorts in the different layers and spatial scales examined. The first layer and the second layer of I. lanceolatum weren’t repellent at different scales，which showed that it was strongly tolerable to the shade. The spatial associations indicated that I. lanceolatum and M. thunbergii were significantly positively associated. The negative association among cohorts increased and the positive association was decreased as the scales increased. By occupying different horizontal and vertical spaces and having different life history strategies，the dominant species of the community could co-exist，resulting in rich biodiversity in the studied community. ［Ch，5 tab. 23 ref.］
