摘要:
华木莲(Sinomanglietia glauca)是我国特有的珍稀濒危植物,属典型极小种群. 为厘清该种群的生存现状与濒危机制,制定有效的保护策略,本研究基于1 hm2华木莲连续样地调查数据,以种群径级结构代替年龄结构,编制静态生命表,建立时间序列预测模型,进行生存分析,探讨华木莲的种群特征及动态. 华木莲群落内共有维管植物48科82属133种,毛竹(Phyllostachys edulis)为群落优势种,重要值为48.7; 其次为华木莲,重要值为5.86. 乔木层重要值前10的物种中仅华木莲、黄檀(Dalbergia hupeana)为落叶树种,华木莲群落次生性明显,其种群主要分布在竹阔混交林; 华木莲种群年龄结构呈“金字塔”形,其幼苗数量较多,随径级增大个体数显著降低; 其存活曲线属于DeeveyⅢ型,即前期种群数量呈锐减趋势. 时间序列预测分析表明,该种群在经历2、4、6和8个龄级时间后,存活的大径级个体数量会呈现上升趋势; 生存分析表明,该种群前期生存率低,累计死亡率高,但由第Ⅳ龄级进入第Ⅴ龄级阶段种群的危险率则会大幅下降,至第Ⅷ龄级进入衰亡期. 华木莲种群总体呈前期锐减后期衰退,致使其种群数量增加及种群扩散受阻,形成极小种群. 在华木莲的就地保护中,应适当疏伐伴生树种,降低郁闭度,调整种间关系,以促进不同龄级良性更新.
Abstract:
Sinomanglietia glauca is a rare and endangered plant endemic to our country. It is a typical extremely small population plant. In order to clarify the survival status and endangered mechanism of this population and formulate effective conservation strategies,based on the data of 1 hm2 Sinomanglietia glauca continuous plots,a static life table was compiled with population size class structure instead of age structure,and a time series prediction model was established for survival analysis,the population characteristics and dynamics of Sinomanglietia glauca were studied. 133 species of vascular plants belonging to 48 families,82 genera were found in Sinomanglietia glauca community. Phyllostachys edulis was the dominant species with an importance value of 48.7,followed by Sinomanglietia glauca with an importance value of 5.86. Only Sinomanglietia glauca and Dalbergia hupeana were the deciduous tree species in the top 10 tree layer important values. The secondary character of Sinomanglietia glauca community was obvious,and its population mainly distributed in the mixed forest of bamboo and broad-leaved. Sinomanglietia glauca population had a pyramid-shaped age structure,characterized by having many seedlings and the number of individuals decreasing significantly with the increase of diameter class. Time series prediction analysis showed that the number of large diameter individuals increased after the population experienced 2,4,6 and 8 age classes. The survival analysis showed that survival rate of the population was low and the cumulative mortality rate was high in early stage,but the mortality rate decreased sharply from the IV age group to the V age group,and the population declined in the Ⅷ age group. The population of Sinomanglietia glauca decreased sharply in the early stage and declined in the later stage,which made the population increase and population diffusion hindered and formed the extremely small population. In the in situ protection of Sinomanglietia glauca,it is necessary to thin the associated tree species appropriately,reduce canopy density and adjust interspecific relationship,so as to promote benign regeneration of different age classes.
