Abstract: The litterfall of mangrove forest is important as primary production to the energy flow and matter cycling in esturine ecosystem. The litterfall production of mangrove forest is high, which exceeds 8t穐a-1穣r-1. It becomes organic detritus after destroyed by mechanical force and decomposed by microorganisms. In the decomposition process of organic detritus, there is a reduction in C/N ratio and increment in protein content and caloric value, which is a high nutritive food source for detritus consumers in estury. The organic detritus of mangrove forest presents a major storage, transport and buffer mechanism for the esturine ecosystem. It guarantees the fishery production in esturine and coastal regions.
