大亚湾马鞭洲大型爆破对周围水域环境与海洋生物影响的评估

为了掌握大亚湾马鞭洲岛大型爆破对周围水生环境和海洋生物的实际影响。对爆破现场进行了监测。并对爆破产生的效应做了评估。结果表明，马鞭洲岛周围水域的14项水质指标在爆破后24h内均恢复正常水平；表层沉积物9项指标在爆破后未发现明显异常；爆破对浮游动物的种类构成和生物量没有明显影响；对鱼卵仔鱼影响的最远距达2000m，并在爆破24h后影响范围内的鱼卵仔鱼数量尚无明显恢复迹象；爆破后渔获量明显降低，对距爆心2000m以内水域的海洋经济种类造成直接损害和持续性影响。

Evaluation for the impact of large explosion at Mabianzhou Island on the neighboring aquatic environment and marine organisms in Daya Bay

In order to find out the actual impact of the large explosion at Mabianzhou island on the neighboring aquatic environment and marine organisms in Daya bay, the explosion scene was monitored and the impact effect was evaluated. The result showed that 14 indexes of the water quality around the waters of Mabianzhou island returned to the normal levels in 24 hours after the explosion, while 9 indexes of the surface sediment did not appear obviously abnormal. The explosion did not affect obviously the species structure of zooplankton and biomass. The farthest distance of the impact on the fish eggs and young fish reached 2 000m, and no obvious evidence showed that the quantity of fish eggs and young fish under the range of impact returned to normal 24 hours after the explosion. The fishing yield decreased sharply after the explosion, and the commercial marine species around the waters within a radius of 2000m of the explosion center were damaged directly and affected continuously.
