摘要
以辽宁省营口段海域为案例,应用突变理论,根据1998—2007年的实测数据分别计算了二道沟、望海寨、仙人岛、鲅鱼圈海域的水体富营养化环境灾害性、难降解有机污染物环境灾害性、重金属污染物环境灾害性风险。计算结果表明,2004年以前,营口海域均有发生水体富营养化灾害的风险,局部海域有发生难降解有机物灾害的风险,发生重金属灾害的可能性极小;2005年以后,营口近岸海域发生各类环境灾害的风险都有所降低,但是与其他类型灾害相比,水体富营养化灾害仍然是营口海域环境的潜在风险。
According to the actual data of Erdaogou, Wanghaizhai, Xianrendao, and Bayuquan from 1998 to 2007, the catastrophe theory was used in calculating the possibility of an environmental disaster occurring in these regions, which includes eutrophication disaster, heavy metal disaster and organic pollution disaster. The results revealed that all the regions of near - shore coastal water of Yingkou have the risk on eutrophication disaster, and some local sea areas may occur the heavy metal disaster, but the risk of organic pollution disaster is smaller before 2004. After 2005, the risk on all the types of disaster had gone down in near - shore coastal water of Yingkou, but comparing with other types, the eutrophication disaster was still a potential threat to the near - shore coastal water of Yingkou. The above conclusions have a direct relationship with the development of the industrial structure＇ s history in Yingkou, are also consistent with the relevant historical data.
