湛江电厂对周围水域生态的影响分析

Impact analysis of Zhanjiang Thermal Power Plant to aquatic ecosystem in Maxiehai canal

调查和实测资料分析结果表明,湛江电厂对麻斜海水生生态的影响主要局限于排水口附近温升在2℃以上的狭小区域,电厂温排水引起的温升对浮游生物和鱼类的影响表现为夏季在强增温区内使生物物种和数量减少,而对整个渔业生产和海洋微生物的生长不会产生明显影响,但电厂取水对麻斜海大型水生生物和鱼类会造成冲撞危害。

It is shown by the results of analyzing investigating and field detected data that the impact scope of Zhanjiang thermal power plant to the aquatic ecosystem in Maxiehai canal is mainly limited within the narrow area with 2C temperature increases,which is close to the drainage outlet.The impact of water temperature increase caused by the warm water drainage from the plant to plankton and fish behaves as the decreases of kinds and quantity within the high temperature increase area in summer,and litde influence to fishery production and ocean microbes.But the process of water intake to the plant may form punching and ramming harms to big aquatic organisms and fishes.
