报道了1992年5~9月对晋江对虾养殖垦区虾池Chla、COD、DIN、DIP和初级产量等富营养参数的调查结果.这些参数的量值在养殖期间逐渐上升.夏季Chla平均含量为22.2mg/m ̄3,初级产量达到2254mg/m ̄3·d.8月份大部分虾池COD值约为海区的3倍.营养盐含量在养殖期间也有变化.无机N平均值为14.8μmol/L,养殖后期的比率大大高于早期.调查结果表明,虾池是一个高度富营养化的人工生态系,通过虾池与邻近海区的水交换,将可能加速后者的富营养化过程.
This paper reports the survey results of eutrophication parameters such as Chla, COD, DIN, DIP and primary production of shrimp ponds in Jinjiang shrimp farming reclamation area from May to September in 1992. The magnitude of these parameters gradually increases during aquaculture. Summer Chla average content of 22.2mg / m ~ 3, the primary production reached 2254mg / m ~ 3 · d. Most shrimp ponds in August COD value of about 3 times the sea area. Nutrients also vary during cultivation. The average value of inorganic N was 14.8μmol / L, and the rate of the later breeding was much higher than that of the early stage. The findings indicate that the shrimp ponds are highly eutrophic artificial ecosystems and will probably accelerate the eutrophication of the latter through the exchange of shrimp ponds with water in the adjacent sea areas.
