摘要:: 通过使用沉积物捕获器获取沉积物，研究了一生态综合养殖池塘的沉积作用，并利用室内模拟实验研究了缢蛏（Sinonovacula constrzcta)的生物沉积作用，同时分析了池塘沉积物及其间隙水的营养盐；应用Fick第一定律对池塘沉积物-池水界面营养盐通量进行了估算.藻类池颗粒物质的日平均沉积速率为44.59 g/m²，贝类池颗粒物质的日平均沉积速率为14.01 g/m²；两个池塘试验期内(90 d)N、P的净沉积量分别为6061.5 g和3411 g(采样池塘面积各0.5 hm²，水深50~60 cm).结果显示实验期内生态综合养殖池塘沉积作用分别占N、P营养元素输出的2.2%和5.8%（质量分数）.

Abstract:: Deposition in aquaculture areas of an Integrated Multi-trophic Aquaculture(IMTA) Pond in Yunxiao and Zhangzhou was studied by sediment traps which were used to collect sediment.By studing the biodeposition of Sinonovacula constrzcta by indoor simulation experiments,and analysing the amount of NO3--N，NO2--N，NH4+-N，PO43--P of the overlying and interstitial water in the IMTA Pond at the same time.The fluxes of dissolved inorganic N，P from the sediments were estimated by the Fick＇s first law.The estimation results show that the average daily deposition rate of particulate of the algae pool is 44.59 g/m²，while in the shellfish pool the data is 14.01g/m².The total net deposition of N and P in the experimental period(90 d) is 6061.5 g and 3411 g（pool area is 0.5 hm^2;pool depth is 50~60 cm）.The results show that the nutrient N and P contributed by seepage took part about 2.2% and 5.8% of the whole output.
