摘要: 红树林生态系统中存在明显的分带现象,影响其分带的因素包括自身因素和环境因素。自身因素主要有繁殖方式的差异、繁殖体散布能力(包括大小、形状、漂浮性等)和定植能力(如根萌时间等)、繁殖体能量积累(从花到成熟繁殖体单位质量的能量增加值)、幼苗解剖和生理学特征。环境因素主要有土壤理化条件(如盐度、氧化还原状况、pH、硫含量)和生物因素(动物啃食、种间竞争)。上述每种因素在特定的区域都有可能成为影响红树林分带的主要因素。

Abstract: It is obvious that the mangrove forest ecosystem has zonation phenomenon, and the factors influencing mangrove zonation including inherent and environmental factors. Inherent factors include the difference in reproduction types, dispersal capacity of propagule (size, shape, buoyancy, etc.) and anchoring ability (such as rooting time), propagule energy accumulation (increasing energy per unit mass from flower to mature propagule), anatomical and physiological characteristics of seedlings. Environmental factors include soil physiochemical conditions (salinity, redox, pH and sulfur content) and bio-factors (animal predation, interspecific competition). Each factor described above may be the main factor influencing mangrove zonation in a special region.
