本文主要根据1983年6月在莱州湾现场模拟水中爆破勘探石油对水产资源的影响实验,分别实验了爆破所产生的声压波对鱼、虾、蟹、贝类和浮游生物的影响,采集并分析了爆炸前后的海水样品。由实验结果得出,水中爆破对海水水质的影响主要因素是:悬浮物、无机氮等。水中爆破所产生的声压波对海洋生物有一定的致死作用,但致死范围不大,而对水产资源的幼体和浮游生物伤害较大。
This paper mainly based on the experiment of simulating the impact of oil blasting on aquatic resources in Laizhou Bay in June, 1983, and experimentally studied the effects of sound pressure wave generated by blasting on fish, shrimp, crab, shellfish and plankton respectively. The seawater samples before and after the explosion were analyzed. The experimental results show that the main factors affecting the water quality of seawater blasting are: suspended solids, inorganic nitrogen and so on. Sound pressure waves generated by underwater blasting have some lethal effects on the marine life, but the lethality is not large, but the damage to the larvae and plankton of aquatic resources is greater.
