摘要
以2002—2015年水质环境调查数据为基础,利用主成分分析法(Principal Components Analysis,PCA)分别对大鹏液化天然气LNG(Liquefied Natural Gas)接收站附近水域以及大鹏湾海域的水质环境变化情况进行了分析,在对海域污染变化情况分析的基础上,比较了大鹏液化天然气接收站附近水域和大鹏湾海域的水体环境的变化趋势,辨析了大鹏液化天然气接收站运营前后对区域水体环境的影响。研究表明,大鹏湾海域整体水质状况和各水质级别海域面积占比较为稳定,其海域内污染源的情况也处于基本稳定的状态,接收站附近水域和大鹏湾海域水体环境呈现一致的变化趋势,大鹏液化天然气接收站对大鹏湾海域以及其附近水域水体环境质量几乎没有产生影响。
Based on the water quality investigation data from 2002 to 2015 by using principal component analysis,we analyzed the water quality of the sea area nearby LNG receiving station and the water quality of Dapeng Bay,compared the variation trend of them,discriminated and analyzed the influence of LNG receiving station in Dapeng Bay on water environment before and after station operation.Result shows that the water quality of entire Dapeng Bay and the ratio of different water quality areas are stable.The pollution source in whole sea area is also basically stable.The variation trends of water quality in areas near receiving station and Dapeng Bay are similar,indicating the LNG receiving station has almost no effect on water quality in Dapeng Bay and its nearby water area.
