摘要
阐述了河北省海兴县海岸带河流、近海污染现状及演变趋势。调查分析表明,80年代以来,海岸带河流和近海水质污染日趋加重,污染物主要源自陆源输入,输入渠道包括漳卫新河、宣惠河及大口河,因此需严格控制其水质及输入量;海水中重金属在晒盐过程中逐级富集,并沉积于盐体内。并对杨埕水库水质进行了调查研究。
The pollution statues of rivers and coastal water and their changes in Haixing County were evaluated. The investigation results showed that the pollution is becoming more serious. Pollutants are mainly from inland sources such as Zhangweixin River,Xuanhui River and Dakou River. The heavy mentals in sea are gradually accumulated during the procedures of making salt in sun. The water quality at Yangcheng reservoir was also investigated.
