本文介绍在一个受干扰的红树林生态系统中有关动植物区系的初步研究。该红树林的种群分布带明显地体现在两个优势树种海榄(Avicennia marina)和杯萼海桑(Sonneratia alba)上。靠陆地林缘区几乎由海榄组成纯林,而且,这一树种在林区内广泛分布。杯萼海桑几乎完全占领海上林缘区。方蟹类生活在林区中基质相对较坚实的陆地林缘。另一方面,沙蟹类生活在混合交错地带,主要在稠密红树林以外的沙质/泥质地段和空旷的滩涂地带。偶而可在红树林陆地林缘的沙底见到沙蟹。软体动物Cerithideadecollata在海榄红树林中普遍出现,而在海上林缘和滨海地带红树林中出现其它种类的软体动物。根据红树林的植物区系、凋落物以及方蟹类的分布,本文提出了该生态系统中有机碳通量的概念模型。
This article presents a preliminary study of flora and fauna in a disturbed mangrove ecosystem. The population distribution of this mangrove forest is clearly reflected in the two dominant species, Avicennia marina and Sonneratia alba. By the land marginal area almost composed of pure sea Lam, and this tree species are widely distributed in the forest. Cup calyx sea almost completely occupy the maritime margin. Crabs living in forest areas in the relatively solid substrate land edge forest. On the other hand, sand crabs live in a mixed zone of intertwining mainly in sandy / muddy areas and open beach areas outside dense mangroves. Occasionally in mangrove land edge of the sand see sand crab. Mollusc Cerithideadecollata is commonly found in the mangrove forests of Hailar, while other species of molluscs are found in the mangrove forests at sea and coastal areas. According to the distribution of mangrove flora, litter and square crabs, a conceptual model of organic carbon flux in this ecosystem is proposed in this paper.
