从悬沙浓度、底质类型分布、冲淤演变历史以及冲淤控制因素等方面对泉州湾淤积现状进行了阐述与分析。利用AQUAfast II浊度仪对泉州湾典型淤积海域进行了浊度测试,分析了其悬沙浓度,归纳出泉州湾底质主要可划分为细沙、粉沙和粘土,并指出了其分布情况;结合近32 a来泉州湾典型区域湾底平面高程的资料,分析了该高程的变化及淤积量、淤积速率等。通过分析得出,造成泉州湾淤积的主要因素包括潮汐、波浪、河流以及人类活动等四个方面。
The present situation of sedimentation in Quanzhou Bay was described and analyzed from suspended sediment concentration, distribution of sediment types, evolution history of scouring and silting, as well as controlling factors of scouring and silting. The turbidity of typical silted waters of Quanzhou Bay was measured with AQUAfast II turbidimeter. The suspended sediment concentration was analyzed. The sediment concentration in Quanzhou Bay was mainly divided into fine sand, silt and clay, and its distribution was pointed out. Based on the data of plane elevation at the bottom of Bay in the typical area of Quanzhou Bay during the past 32 years, the change of the elevation and sedimentation rate and siltation rate were analyzed. Through analysis, it is concluded that the main factors causing the deposition of Quanzhou Bay include tidal, wave, river and human activities.
