| 摘 要： | 火(核)电厂、液化天然气(LNG)接收站排放余氯水和取水机械卷载效应均对渔业资源带来影响.本文以LNG接收站工程为例,依据2004年5、8、11月和2005年5月评价水域渔业调查资料,采用渔业资源尾数密度(包括鱼卵、仔鱼生长形成的部分)、受影响的面积和鱼类商品体重的乘积作为计算模式,评估机械卷载和余氯对渔业资源的损失量.结果表明,LNG接收站余氯和机械卷载引起的渔业资源损失量为176.0t/a.本文所采用的评估方法,有助于解决海洋工程影响渔业资源数量评估的实践问题,对渔业资源物损评价标准的制定有一定的参考价值.

| Abstract: | The assessment of the fishery resource loss(FRS) caused by the influence of mechanical entanglement(ME) and residual chlorine(RC) produced in operation of the LNG engineering was done,according to data from the fishery investigation and engineering analysis in May,August,November,2004 and May,2005 in the Yangshan waters,and the amount of FRS was calculated.The product of individual density(including eggs,larva and young fishes),impacting area and weight of the commercial size were studied.The result showed that FRS caused by RC and ME were 111.69 t and 65.11 t per year,respectively.Thus FRS gross in LNG receiving station was 176.80 t because of the influence of ME and RC every year.The count method could be applied to the environmental impact assessment of warm-drain RC and ME from the power plants,so it is widely applicable. |
