针对沿海增养殖业对海洋生态的影响 ,对中国南部沿海 2个增养殖业发达区———南澳岛深澳湾“海上渔村”和赤潮灾区饶平柘林湾进行了实地考察和取样分析。考察发现 ,目前中国南部沿海增养殖业普遍存在技术落后、缺乏科学技术指导和统一管理等问题 ,对海洋生态造成了极大的危害 ;通过海水水质测定实验 ,发现这 2个养殖区水样的平均含氮量较高(2 15 4mg L) ,氮磷质量比较高 (2 2 ) ,处于富营养化状态 ;浮游植物平均密度较高 (190 8 6个 mL) ,个体含叶绿素a量较低 (1 74× 10 -6mg 个 ) ,出现生态衰退现象 In view of the impact of coastal aquaculture on marine ecology, field surveys and sampling analyzes were carried out on two coastal aquaculture-developed coastal areas of South China --- “Marine Fishing Village” in Shenao’ao Bay, Nanling Island, and Raoping River Bay in the red tide affected area. The survey found that coastal aquaculture in southern China is generally backward in technology, lack of scientific and technical guidance and unified management and other issues, causing great harm to marine ecology; seawater quality determination experiments found that the two aquaculture water samples The average nitrogen content was higher (2 15 4 mg L), nitrogen and phosphorus were higher (2 2) and eutrophication. The average density of phytoplankton was higher (190 8 6 mL) (1 74 × 10 -6mg), the phenomenon of ecological decline appears
