摘要: |
为搞清我国陆架的孢粉、藻类分布规律,于1972年先后对黄海、东海、南海海底沉积物作了孢粉、藻类研究。结果表明,在黄海、东海表层沉积物中红树植物花粉主委由黑潮暖流北上携带而来,在南海沿岸的海湾和河流入海处沉积物中红树植物花粉含量高;水下古海岸线附近含量亦高;南海北部钻孔中的红树植物花粉系由海流搬运我国沿岸物质沉积而成;南部钻孔中的红树植物花粉主要是海流将马来西亚和菲律宾沿岸物质搬运沉积而成。 |

Abstract: |
Mangrove flora are special vegetation existing in certain areas of tropical and subtropical coasts. They are the plant indicator of climate and environment. The mangrove pollen distribution in the sediments of the South Yellow Sea and the East China Sea is evidence for inferring the route of the Kuroshio Warm Current, and tracing the origin of the sediments. Their distribution in surface sediments of the South China Sea also provides evidence suggesting its paleoenvironrnent and submaring paleo-shoreline. The study on mangrove pollen distribution in column samples of the South China Sea is important for exploring sediments source, paleoenvironment, paleo-ocean current and paleoclimatical change. |
