摘　　要：厦门西港和九龙江口春季(3月)表层海水TSM含量分别为17.80±6.16和60.11±75.25mg/dm^3,整个调查海区平均为38.96±56.50mg/dm^3。河流输入是河口区悬浮颗粒的主要来源。悬浮颗粒中Si,Al,Fe的含量最大(47.4～190×10^(-3),C,Ca,Mg,Ti,Mn的含量次之(平均在1.6～29.5×10^(-3)),其它元素的含量一般小于1×10^(-3)。因子分布表明:陆源输入、各种地球化学过程以及与生物活动有关的过程是控制悬浮颗粒化学组成的主要因素。The content of total suspended matter (TSM) from the surface seawater of Xiamen Harbour and Jiulong River estuary during March, 1986 were 17.86±6.16 and 60.11±75.25 mg/dm3 respectively. River input is the most important source of suspended particles. The contents of major elements of suspended particles are in the sequence of Si, Al, Fe((47.4-190)×10-3)>POC (29.5×10-3) Ca, Mg, Ti, Mn ((1.6-18.8)×10-3) > P, Ba, Sr, V, Mo, Cu (less than 1 ×10-3). In average, more than 75% of Fe, Al, Si, Ti and Mo were present in the refractory fraction, more than 50% of Mn, Ca, Mg and Sr were present in the weak acid soluable fraction.
