摘要
[目的]监测莱州湾贝类养殖区水质状况,旨在为海洋环境保护及贝类养殖提供参考。[方法]在2019年5—11月对莱州湾的8个位点进行水质监测,并采用营养指数法、营养状态质量指数法和内梅罗环境综合质量指数法对水质进行评价。[结果]莱州湾水温、盐度和pH分别为12.24~27.04℃、29.05‰~30.72‰和7.52~8.22,适宜贝类的养殖;溶解氧和化学需氧量分别为6.55~8.31和1.24~2.25 mg/L,均符合国家二类水质标准;营养盐含量均在贝类养殖的安全范围内;养殖区内细菌数量均在合理范围之内;营养水平和水质评价总体来说该海域较为清洁,但在个别月份营养水平偏高。[结论]莱州湾贝类养殖区水质状况较好,适宜贝类的养殖。
[Objective]The research monitored the water quality of shellfish culture areas in Laizhou Bay,aiming to provide scientific reference for marine environmental protection and shellfish culture.[Method]The water quality of 8 sites in Laizhou Bay was investigated from May to November in 2019.The water quality was evaluated by nutrition index method,nutrition quality index method and Nemerow environmental quality index method.[Result]The water temperature,salinity and pH of Laizhou Bay were 12.24-27.04℃,29.05‰-30.72‰and 7.52-8.22,respectively,which were suitable for shellfish culture.The dissolved oxygen and chemical oxygen demand were 6.55-8.31 mg/L and 1.24-2.25 mg/L,which were accorded with GradeⅡwater quality standards.The nutrient contents were all within the safe range of shellfish culture.The number of bacteria in shellfish culture area of Laizhou Bay was within a reasonable range.Generally,the sea area was relatively clean in terms of nutrition level and water quality evaluation,but in some months,the nutrition level was on the high side.[Conclusion]The water quality in Laizhou Bay is pretty good that is suitable for shellfish cultivation.
