| 摘 要： | 盐地碱蓬是黄河三角洲重要的先锋植物,抗盐能力强,分布范围广,对维持该地区生态系统稳定和演替发挥着重要作用。通过野外取样测定,研究了潮间带和潮上带盐地碱蓬种群的形态及生物量分配特征。在个体大小上,潮间带盐地碱蓬在株高和地径上显著低于潮上带盐地碱蓬;潮上带盐地碱蓬密集分布的株高高于散生分布,而生物量低于散生分布。在生物量分配特征上,潮间带盐地碱蓬Ⅰ以发展花、叶为主,潮上带盐地碱蓬Ⅱ的密集分布以优先发展茎为主,潮上带盐地碱蓬Ⅲ的散生分布以发展枝为主,属于种群发展的稳定阶段。因此,盐地碱蓬通过形态特征及生物量分配特征的调节,以适应潮间带和潮上带的不同生境特征,从而达到种群维持和土壤改良的目的。

| Abstract: | Suaeda salsa with a strong salt tolerance and wide distribution is one of the most important pioneer species and plays an important role in the stability and succession of ecosystem in the Yellow River Delta.Biomass allocation of S.salsa population in the intertidal and supratidal zone was studied.On the individual size,plant height and basal diameter of S.salsa in the intertidal zone were higher than that in the supratidal zone.Comparing with the scattered distribution,S.salsa in the intertidal zone had hi... |
