为摸清长江口总体污染情况,通过查阅大量的文献资料,从地理位置、污染程度、海洋功能等方面对长江口污染控制区进行了划分;按地理位置把长江口分为南支、北支、南北港、南北槽4个污染控制区,按污染程度从长江口内向东依次分为严重污染海域区、中度污染海域区、轻度污染海域区、较清洁海域区和清洁海域区,按照海洋功能标准把长江口划分为港口航运区、渔业资源利用和养护区、旅游区、海水资源利用区、海洋保护区、特殊利用区、工程用海区和保留区。研究初步分析了长江口的总体污染现状,为长江口将来的环境规划、治理、发展和建设提供参考。
In order to find out the general pollution in the Changjiang Estuary, by referring to a large amount of documents and materials, the pollution control areas in the Changjiang Estuary were divided from the aspects of geographical location, degree of pollution and marine functions. According to the geographical location, the Changjiang Estuary was divided into South Branch and North Branch , South and North ports, North and South trough four pollution control areas, according to the degree of pollution from the mouth of the Yangtze River Estuary were divided into serious polluted sea area, moderate polluted sea area, slightly polluted sea area, cleaner sea area and clean sea area, according to The marine functional standard divides the Yangtze Estuary into port shipping area, fishery resource utilization and conservation area, tourist area, sea water resource utilization area, marine protection area, special use area, engineering sea area and reserved area. The study initially analyzed the overall pollution in the Yangtze Estuary and provided reference for the future planning, governance, development and construction of the Yangtze Estuary.
