摘要
对江苏中部潮滩 1年中 12个月的沉积样品的孢粉分析结果表明 ,潮滩沉积存在明显的季节性孢粉特征 ,可以利用孢粉指标来指示与判别潮滩沉积的季节性。
monthly sedimentary samples are collected from the modern tidal flat surface on Dafeng of Jiangsu.Palynological analysis of these samples indicates that the seasonal palynological features of the tidal flat sediment are very obvious and some palynological indexes such as taxon percentage of Arboreal and Herbaceous pollen and spore are good indicators for telling the seasonality of the tidal flat deposits.A sedimentary sequence formed between 1984 and 1994 is used to check this method.Checking result suggests that this method is acceptable and the taxon percentage of Arboreal pollen is the best indicator for the seasonality study of tidal flat deposits.
