摘要
在2004年11月17日对胶州湾西部扇贝养殖区及周围海区进行的综合海洋环境调查的基础上,分析了胶州湾秋季扇贝养殖区与非养殖区的海洋环境状况,初步探讨了扇贝养殖在收获期对养殖区环境的影响。胶州湾养殖区表层水中COD和无机营养盐含量,除了NO2 -N的变化不明显外,均高于非养殖区的值。养殖区底层水中溶解氧含量和表层沉积物中硫化物的含量均明显超标。因此,肢州湾的扇贝养殖在收获期对环境的影响也是综合性的,且养殖海域的环境同时受陆源、水动力状况及养殖活动的综合影响。
Based on the surveys of the cultiveated water in Jiaozhiu bay in Nov. 17, 2004, the horizontal distributions of environmental parameters are analyzed, and the impacts of scallop cultivation on water quality in harvest time are preliminarily discussed. The concentrations of COD, NH4-N and PO4-P inside the raft culture area are higher than those outside in the surface water in Jiaozhou Bay, but there was on obvious variation in nitrite between the culture and non-culture areas. The dissolved oxygen content in the bottom water and sulfide content in the sediment inside the culture area are remarkably higher than the marine aquaculture standard. The observations also found that the affected area did not extend to 1 km away from the rafts in Jiaozhiu Bay. Therefore, the environmental effects of scallop cultivation are comprehensive in harvest time, but only exist near the cultivation area.
