  Analyzing sediment samples with laser particle analyzer,it provides that in the middle of survey area sediments are relatively thick,mostly fine sand,sorting well,majority frequency are almost symmetry form narrow peak curve. Around the survey area sediments are relatively thin,mostly clay fine sand,sorting badly,majority frequency is almost Positive skewness wide peak and middle peak curves.

  通过使用激光粒度仪进行底质样品分析,发现调查区中部泥沙相对较粗,多为细砂,分选好,频率曲线多为近对称态的窄峰型曲线;调查区四周泥沙相对较细,多为粘土质粉砂,分选差,频率曲线多成正偏态的宽峰型和中等峰型曲线。
