1992年9月13日,在双台子河口现场模拟水中爆炸勘探石油实验,采集井分析了爆炸前后的海水样品,发现爆炸对海水水质影响的主要因素是:悬浮体、无机氮等,从模拟实验的结果分析得出:水下爆炸对海洋洄游鱼类伤害少,而对水产资源的幼体,卵类和海蜇伤害大的结论。)在这一带海域栖息。水下爆破可使位于爆炸中心附近的上述贝类和其它底栖生物当场毙命,除受强声压致死的外,那些致昏而处于半致死状态的贝类和其它底栖生物,在遭到由爆炸激起的大量泥沙沉降掩埋之后,也难逃窒息死亡的命运。所以,水下爆炸对底栖经济贝类也有一定的影响。3结论由水下爆炸对鱼类致死的实验模拟和爆炸前后的水质分析,可得出下述结论:1.水中爆炸对海洋环境的主要影响因子是:浊度、悬浮体和无机氮的增高,而其它污染物没有明显的变化,亦无影响。2.爆炸产生的声压波对鱼有一定的致死作用,其致死范围较小,有效半径约50m。3.爆炸对渔场的危害,主要是在禁渔期内,是对鱼虾和贝类的卵和幼体以及海蜇资源的危害。4.在渔场使用水中爆炸声进行海底石油勘探作业,应避开禁渔期和捕捞旺季,或者改用非炸药震源,如电磁脉冲震源、空气枪震源等 ̄[4]。这样,可使渔业资源的损失降到最低的程度。致谢:本实?
On September 13, 1992, an in-situ explosion experiment was conducted in Shuangtaizi Estuary. The samples collected before and after the explosion were analyzed. The main factors affecting the seawater quality were: suspended solids and inorganic nitrogen. From the simulation experiments The result of the analysis shows that the underwater explosion has less harm to the marine migratory fish and has a greater injury to the larvae, eggs and jellyfish of the aquatic resources. Habitat in the sea area. Underwater blasting can kill the shellfish and other benthic creatures located near the center of the blast, killing all those lethal and lethal shellfish and other benthic organisms, After the large amount of sediment infiltrated by the explosion buried the land, it is difficult to suffocate the fate of death. Therefore, the underwater explosion on the benthic economic shellfish also have a certain impact. 3 Conclusion From the underwater explosion lethal test simulation of fish and water quality before and after the explosion, can draw the following conclusions: 1. The main impact factors of marine explosions on the marine environment are: turbidity, increase of suspended solids and inorganic nitrogen, and no obvious change of other pollutants. 2. Sound pressure waves generated by the explosion have a certain lethal effect on fish, and their lethal range is small with an effective radius of about 50m. 3. The damage to the fisheries caused by the explosion, mainly during the closure period, is a hazard to the eggs, larvae and jellyfish resources of fish and shrimp and shellfishes. 4. The use of underwater explosions in the fishing ground for oil exploration operations should avoid the fishing season and fishing season, or use non-explosive sources, such as electromagnetic pulse source, air gun source [4]. In this way, the loss of fisheries resources can be minimized. Acknowledgments: The reality?
