摘  要:
为了阐明不同潮位下角果木Ceriops tagal种群的发展趋势,合理利用与保护现有的红树物种资源,通过野外样方调查与室内分析的统计学方法对不同潮位下的角果木种群进行调查,综合比较分析不同潮位生境下角果木的年龄结构,存活曲线与及静止生命表的差异,探究不同潮位生境下角果木的种群结构变化规律与发展趋势。构建高潮位生境下的种群动态的时间序列预测模型,预测了角果木种群其随着时间的变化种群的发展状况。结果表明,高潮位的生境下角果木种群呈现典型的"金字塔"增长型结构,种群处于不断增长趋势,存活曲线表现为凹形,即为DeeveeyⅢ。在低潮位的生境下,角果木的幼苗较多,但在生长发育过程中出现生长"瓶颈"现象,幼苗较难发育至成体树,种群呈现衰退的趋势。时间序列模型表明,高潮位生境下的角果木处于健康稳定的增长状态,种群的生长发育随着时间的变化而呈现出稳定的增长态势。

摘  要:
In order to clarify the trend of the Ceriops tagal population age structure and future development, protect and make full use of the existing resources, we gathered datum under different tidal field quadrat randomly, explored different tidal habitats Ceriops tagal population structure variation with the age structure of Ceriops tagal, survival curve and still life table, and predicted the population development of Ceriops tagal with the time series prediction model of population dynamics.The result shows that Ceriops tagal populations are increasing with the structure of typical pyramid and the concave survivorship curves, namely for Deeveey Ⅲ. In the low tide level there are a certain number of Ceriops tagal seedlings, however, it is more impossible for the seedlings to develop into mature trees, showing a growth bottlenecks and a trend of population decline. Time sequence prediction indicates that Ceriops tagal population is in the stable development in high tide environment.
