摘要: |
采用模糊综合评价法, 根据2009年5个月份和2010年6个月份的东极大黄鱼(Larimichthys crocea)养殖区海水水样监测数据, 对该养殖区海水水质状况进行了综合评价。结果表明, 在年均值的评价中, 2009 年和2010年养殖区海水水质均为一类水, 对一类水的隶属度分别为0.53和0.80, 说明2010年的水质状况好于2009年。2010年6个监测月份的评价结果显示, 各监测月份水质状况均为一类水质, 但各月水质状况对一类水的隶属度值差别较大。4月份和5月份的水质状况对一类水的隶属度在0.5以上, 6 月份的水质状况对一类水的隶属度最低, 仅为0.33, 其余监测月份海水水质对一类水的隶属度均小于4、5月份。评价结果与东极大黄鱼养殖区水质的实际状况相符, 说明模糊综合评价法适用于养殖区海水水质的评价。 |

Abstract: |
We assess the surface seawater quality of Larimichthys crocea mariculture areas at Dongji comprehensively using fuzzy comprehensive assessment (FCA), based on the monitoring data of 5 months in 2009 and 6 months in 2010. The results indicate that: the annual average value of the water quality in 2009 and 2010 both belonged to class 1, the membership degree to class 1 was 0.53 and 0.80, respectively. The membership degree to class 1 in 2010 was higher than in 2009. In a word, the water quality condition in 2010 was better than in 2009. In the assessment of each monitoring month, the water quality condition of 6 months in 2010 all belonged to class 1, however, the membership degrees of each month was obviously different. The membership degree to class 1 of April and May were both above 0.5, while the one of the other months were less than 0.5. The result is coincident with the fact, which indicates the method can be used in the water quality comprehensive evaluation of mariculture areas. |
