摘要
分别于2011年5月、8月、11月和2012年2月在黄河口水域选取6个调查站位,对该水域的营养盐、重金属和石油类等水质指标进行4个航次的调查,并采用内梅罗指数和综合营养状态指数法对水环境质量进行了评价。结果表明,黄河河口水环境总体属于轻度至重度富营养化水平,富营养化指标以总氮、总磷最为严重,其他指标均未超标。
To understand the spatial and temporal distribution characteristics of water quality in Yellow River Estuary,four investigations were conducted in May,August and November of 2011and February of 2012.And the environment was evaluated based on Nemero index and nutritional status index(TLI).The results showed that water quality of Yellow River Estuary was at the stage of light eutrophication to high eutrophication. And the water was seriously polluted by TN and TP while all the other being under the standards.
