海桑属(Sonneratia)植物是热带滨海特有的盐滩植物,是气候和环境的指示植物,其花粉可作为滨海相沉积的重要标志。此属花粉在南海南部晚第四纪地层中分布较广,在南海中部的深海盆地,由于海流的影响,也有少量的断续分布,而处于南海北部的香港地区,在晚更新世中晚期的地层中,曾大量出现过。分析海桑属花粉在晚第四纪地层中的分布,对深入研究南海海区的物质来源、古环境和古气候等有着重要的意义。
Sonneratia plants are unique salt flats of the tropical coast and are indicative of climate and environment. Their pollen is an important symbol of the deposition of the coastal facies. This pollen is widely distributed in the Late Quaternary strata in the southern South China Sea. In the deep-sea basin in the central South China Sea, due to the influence of ocean currents, there is also a small amount of intermittent distribution, while in the Hong Kong area in the northern part of the South China Sea, Stratum, there have been a large number of. Analysis of the distribution of Haisong genus pollen in the Late Quaternary stratigraphy is of great significance for the further study of the material sources, paleoenvironment and paleoclimate in the South China Sea.
