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 TSM contents of surface waters in the west of Xiamen and the Jiulongjiang estuary in spring (March) were 17.80 ± 6.16 and 60.11 ± 75.25mg / dm ~ 3, respectively, and the average sea surface area survey was 38.96 ± 56.50mg / dm ~ 3. River input is the main source of suspended particles in the estuary. The contents of Si, Al and Fe in the suspended particles were the highest (47.4 ~ 190 × 10 -3), followed by C, Ca, Mg, Ti and Mn (1.6 ~ 29.5 × 10 -3) , And the content of other elements is generally less than 1 × 10 -3 .The distribution of factors shows that the input of terrestrial sources, various geochemical processes and the processes related to biological activities are the main factors controlling the chemical composition of suspended particles.
