长江口及毗邻海域水环境现状与污染防治对策

Water Environment Status and Pollution Prevention and Control in Yangtze River Estuary and Adjacent Waters

长江口及其毗邻海域作为具有多种功能的重要海域,水体质量越来越多的受到人类活动的影响。该文基于国家海洋环境质量公报,以及相关监测站对长江口海域的监测数据,分析研究了长江口水环境状况。结果表明,长江口水域水质整体上受到污染加重、咸潮入侵以及湿地生态环境破坏的影响,水质常年处于劣四类。分析认为,陆源不合理排污、近岸大型工程建设及滩涂围垦等人为因素是主要原因。针对存在的环境问题,提出了相应的治理措施,为今后长江口水域环境质量的不断提升提供借鉴。

Yangtze River estuary and the adjacent waters are more and more affected by human activities,as an important area. The condition of water environment in Yangtze River estuary and its adjacent waters are analyzed,by referring to the literature and making the reference to the monitoring data getting from the ocean official gazette of the Yangtze River estuary. The key problems are the terrestrial drainages,saline water intrusion and wetland ecological environment destruction because of unreasonable drainage,water conservancy project construction,and land reclamation on tidal flat. The perennial water quality is below four degree. This paper explores these questions and introduces the suggestions for the future comprehensive treatment.
