| 摘 要： | 为了定性定量提供大蚝养殖区环境健康状况咨询，使用联合评价法对钦州湾大蚝养殖育苗区、育肥区、育成区环境健康状况进行评价。结果表明：①钦州湾养殖育成区、育肥区、育苗区的综合评价值为0.62、0.75、1.03，对应环境健康状况分别为良好、良好、不合格。健康状况呈现出由东南外湾的育成区向西北内湾的育苗区方向递减趋势，各养殖海区环境健康状况优先次序为：育成区、育肥区、育苗区。②制约钦州湾养殖区环境健康状况既有共性制约因素石油类，其环境健康状况均为不合格；也有特性制约因子COD、活性磷酸盐。其中，育苗区内COD单因素评价指标值变化范围1.34～2.21，对应健康状况为差，海域大多位于海湾内、外湾交界处以及河海口交汇处，而处于外湾的育肥区、育成区则处于海湾开阔的海域受到COD影响则较小。育肥区内活性磷酸盐单因素评价指标值对应健康状况也存在不合格和差的情况。

| Abstract: | In order to provide advice on the environmental health status of oyster culture areas,the joint assessment method was used to evaluate the environmental health status of the oyster culture nursery area,fattening area and breeding area of Qinzhou Bay.The results showed that: 1.the comprehensive evaluation values of culture breeding area,fattening area and nursery area in Qinzhou Bay were 0.62,0.75 and 1.03,respectively,which were good,good and unqualified.The health status showed a trend of decreasing from the southeast outer bay breeding area to the northwest inner bay seedling area,and the environmental health status of each cultured sea area was prioritized: Breeding District > Fattening Area > Nursery Area.2.Restricting the environmental health status of the culture area of Qinzhou Bay has both common constraints,petroleum,and its environmental health status is unqualified;there are also characteristic constraints COD,active phosphate.Among them,the change range of COD single factor evaluation index in the nursery area is 1.34~2.21,which is poor in health status.Most of the sea area is located at the junction of the inner and outer bays of the bay and the intersection,while the fattening area and the breeding area of the outer bay are at the open seas of the bay are less affected by COD.The single factor evaluation index value of active phosphate in the fattening area also has unqualified and poor conditions corresponding to the health status. |
