在本研究中，使用自动升降仪测量潮滩的水质，该仪器长期收集不同深度的水力数据和水质数据。对数据的分析，重点是悬浮物，揭示了悬浮物在不同潮汐时期的变化和分布。从所获得的测量中成功地提取了关于潮滩各种物理特征的波动信息。阐明了水位变化条件下滩涂泥沙输移的一些特点。这项研究还试图考虑SS和营养盐的迁移，从而研究它们的特征和侵蚀对水质的影响。因此，可以说，T-N和T-P在很大程度上依赖于泥浆侵蚀行为。它们对水质的影响很大，而在这次有限的调查中，DIN和DIP可能不会受到泥沙侵蚀的明显影响。利用泥沙捕集器和观测塔对泥滩上悬浮物的行为进行了研究。泥沙沉降量和营养盐的分析结果揭示了泥滩沉降物的特征。测得的沉降通量与理论计算得到的净沉降通量基本一致。根据本研究中测得的沉降量估算了泥滩的沉降量。通过对3个水塔观测资料的检验，揭示了该地区细粒粘性泥沙的输移特征，并通过实验提取了其偏爱因子。在综合适宜度指数的基础上，对其栖息地进行了评价。
英文摘要
In this study, water quality in a tidal flat is measured using an automatic ascending-descending instrument that collects hydraulic data and water quality data at various depths over a long period. Analysis of the data, focusing on suspended solids, reveals the variations and distribution of suspended solids in different tidal periods. Information regarding the fluctuation in various physical characteristics of tidal flats was successfully extracted from the obtained measurements. Some of the characteristics of sediment transport over mud flats under the variations of water level were also clarified. This research also attempts to consider that the movement of SS and nutrients, and thus their characteristics and the influence of erosion to water quality are investigated. As a result, it can be said that T-N and T-P are much dependent on the behaviors of mud erosion. They contribute a great effect to the water quality, while DIN and DIP may not be affected clearly by the mud erosion in this limited survey. In addition, parts of nutrients leached in the water from eroded matters were adsorbed to suspended matters again.Behaviors of suspended matters on the mud flat were investigated by using the sediment-traps and observation towers. Results obtained from the analysis of the amounts of sedimentation and nutrients reveal the characteristics of settling matters in the mud flat. The settling flux observed in the sediment-tarps almost coincided with the net settling flux obtained from a theoretical calculation. The amount of sedimentation to the mud flat was also estimated based upon the settling flux measured in this study. It is shown that the fine cohesive sediment transport in the area was demonstrated through examining the observed data in three towers.The preference factors of Sinonovacula constrica were extracted by some experiments. As the results, habitat of Sinonovacula constrica was estimated on the base of composite suitability index.
