摘要
分布于青岛沿海岛屿的山茶(Cameliajaponica),又名耐冬,由于受特殊的自然条件制约和人为活动的影响,在许多方面都不同于亚热带分布的类群.它具有耐适度低温和适度耐荫的生理生态学特性;对分布于长门岩岛的山茶种群统计表明,该种群是一具倒金字塔年龄结构的衰退种群;以山茶为建群种的群落具有较丰富的区系组成和较高的物种多样性.根据山茶的生物学、生态学和种群遗传学特征分析,保护山茶的生境并对山茶种群进行人工抚育和群落结构改造。
Naidong Camellia (Camellia japonica) is distributed on some off-shore islands near mount Lao in Qingdao.Because of the influence of natural conditions and human activities,this camellia population is different from that distributed over the subtropical zone.It has ecological physiology characteristics of coldresistant and shade resistant with in some extent.population statistics on the Naidong Camellia distributed Changmenyan island shown that this population is a declining one which has an age structure of upside down pyramid.The community,its edificator is Naidong Camellia,had abundant floristic compositions and a bit higher species diversity than that near continent.According to the analysis on the characteristics of biology,ecology and population genetics of Naidong Camellia,we think that the habitat conservation,the artificial tending of the population and structure improvement of the community are the main mensures and ways to save and protect the diversity of Naidong camellia.
