摘要
根据黄茅海海域底沙样本的中子活化分析示踪泥沙的原始数据，采用模糊数学方法，计算了各样本点间的相关关系，并进行聚类分析，得出了泥沙输移的主要路线，同时通过对沙源泥沙特性的探讨且结合实际情况，选取了作为沙源的泥沙样本。在此基础上，采用均方差最小的方法，计算各沙源对海域内各样本点的贡献，由此可以确认各沙源的淤积范围，从而对本海域内的泥沙来源有了较为全面的认识。
The main courses of sediment transport in Huang Mao bay are obtained by the relationship which is calculated by the fuzzy mathematical theory and cluster of the samples data determined by neutron activation method. The samples as sediment sources are selected based on actual conditions and analysis of sediment sources characteristics. And the sediment depositional range from each source can be determined by the least squares method.
