为了解庄河临时海洋倾倒区的海洋生态环境现状以及疏浚物倾倒对该海域海洋生态环境的影响情况,本文结合2011~2013年间的监测资料,通过单因子标准指数法以及水质综合污染指数法对倾倒区海水水质进行了评价;采用单因子标准指数法和地质累积指数法,结合2012年和2013年的监测资料对沉积物进行了分析;通过香农-韦佛指数方程,综合2012年和2013年的监测资料,对监测海域的浮游植物、浮游动物和大型底栖生物进行了评价。同时选取倾倒活动影响范围外一点与倾倒区监测同步进行。采用不同方法得到的评价方法均表明,监测海域海水水质基本符合《海水水质标准》中的二类标准;沉积物符合《沉积物质量标准》中的一类标准;海洋生物未受到倾倒物的明显污染。这说明,目前庄河倾倒区海洋生态环境质量良好,疏浚物倾倒未对监控海域生态环境造成明显影响。
In order to understand the status of marine ecological environment in Zhuanghe Temporary Oceanic Dumping Area and the influence of dredged material dumping on the marine ecological environment in this area, this article combines monitoring data from 2011 to 2013, single factor standard index method and comprehensive water pollution index The seawater quality of the dumping area was evaluated. The sediment was analyzed by single factor standard index method and geo-accumulation index method with the monitoring data of 2012 and 2013. Based on the Shannon-Weaver index equation, Of the monitoring data on the monitoring of phytoplankton, zooplankton and large benthic organisms were evaluated. At the same time, we choose the point outside the scope of the dumping activities and the monitoring of the dumping areas simultaneously. The evaluation methods adopted by different methods all indicated that the seawater quality in the monitoring sea area basically met the second type of standard in the “seawater quality standard”; the sediment was in conformity with a kind of standard in the “sediment quality standard”; the marine life was not obvious from the dumping material Pollution. This shows that the present Zhuanghe dumping area has a good marine ecological environment and the dumping of dredged materials has not obviously affected the ecological environment in the monitored waters.
