Abstract：Distributions and seasonal variations of the warm discharge water from the Zhuhai Power Station are analyzed based on the data obtained in July 2009 ,December 2009 and January 2010 .Meanwhile ,the cooling effect of drainage engineering such as surface w ater channel and falling into step is also analyzed using those data .T he results show that taking the outfall as the center ,the further the warm discharge water from the power station moves toward the sea ,the lower the water temperature drops .The sea surface area influenced by the highest temperature rising (4 ℃) is larger in the neap season than in the spring season and in winter than in summer .The drainage ways ap-plied by this power station have different cooling effects .The surface water channel has a certain cooling effect ,but not apparent ;whereas the way of falling into step has a substantial cooling effect ,with the average temperature reduction being about 3 .7 ℃ .
