分别于5月和8月份在黄河入海口及临近海域14个监测点调查采样，并对调查结果进行分析，同时采用ArcGIS软件对河口及邻近海域水质情况进行空间分布趋势研究。结果表明：黄河径流对黄河入海口及邻近海域水环境污染造成了一定的影响；黄河入海口及邻近海域主要受到无机氮、重金属Cu、石油类、DIP的污染；黄河入海口及邻近海域5月份水质污染比8月份严重(Cu除外)；分布趋势特征是入海口污染最重，慢慢向邻近海域辐射、递减；南部半封闭海域尤其近海区域污染较其它海域严重。加强黄河水环境的保护，控制黄河水源的污染可以有效地改善黄河口及邻近海域的水质污染状况。 In May and August, samples were collected at 14 monitoring points in the estuary and adjacent sea areas of the Yellow River, and the survey results were analyzed. Meanwhile, ArcGIS software was used to study the spatial distribution trend of water quality in the estuary and adjacent sea areas. The results show that the runoff of the Yellow River has a certain influence on the water environment pollution of the estuary and adjacent sea areas of the Yellow River. The estuary of the Yellow River and the adjacent sea areas are mainly polluted by inorganic nitrogen, heavy metal copper, petroleum and active phosphate. The water pollution of the estuary and adjacent sea areas of the Yellow River in May was more serious than that of August (except copper). The distribution trend is that the pollution in the estuary is the heaviest and gradually radiates and decreases to the adjacent sea area. The southern semi-closed sea, especially the coastal area, is more polluted than other sea areas. Strengthening the protection of the water environment of the Yellow River and controlling the pollution of the water source of the Yellow River can effectively improve the water quality pollution of the mouth of the Yellow River and the adjacent sea areas.
