浙江天童灌丛群落中优势种群的年龄结构和分布格局

利用每木调查法、时空互代法和相邻格子样方法研究浙江天童地区灌丛群落中4个优势种群的年龄结构和分布格局。结果表明：从年龄结构上看，山矾为稳定剂种群，继木为衰退型种群，苦槠、白栎为增长型种群；从分布格局上看，继木为随机分布，其余3种集群分布。

Studies on the Age Structure and Spatial Pattern of Dominant Populations from Tiantong Shrub Community in Zhejiang Province

By applying the contiguous grid quadrats, the technique of censusing every individual, with the time specific method for life table analysis, it has been studied about the size structure and spatial patterns of dominant populations from Tiantong shrub community in Zhejiang Province. The results show that Symplocos sumuntia is a stable population; Loropetalum chinense is a declining population; Castanopsis sclerophylla, Quercus fabri are increasing populations. Based on analyzing the spatial patterns of these dominant populations, it is shown that only Loropetalum chinense population is of random distribution type while the other populations are of contagious distribution types.
