| 摘要: |
| 根据1998年和1999年的春夏秋冬季节的4次调查资料,分析廉州湾海水温度、盐度及pH值的季节变化和分布特征。结果表明:廉州湾海水温度(平均值),春季22.7℃,夏季35.6℃,秋季27.0℃,冬季18.3℃,变化特征与气温的季节变化相同,空间分布为春夏季河口区水温略高于湾口区,秋冬季则相反;海水盐度(平均值),春季25.6,夏季21.2,秋季26.3,冬季30.3,表现为冬季>秋季>春季>夏季,各季节空间分布的高低差值则刚好相反;海水pH值(平均值),春季8.03,夏季8.32,秋季8.18,冬季8.18,空间分布春夏季高低差值较大,秋冬季高低差值不断减小。廉州湾海水比较适宜开展对虾、文蛤等广温广盐性品种的人工养殖。 |

| Abstract: |
| The seasonal fluctuation and distribution of temperature,salinity and pH value are analyzed according to the measurements of seawater in Lianzhou Bay,Guangxi,Southern China in 1998 and 1999.The results show that the average temperature of seawater is 22.7℃ in spring,35.6℃ in summer,27.0℃ in autumn and 18.3℃ in winter.The seasonal fluctuation of seawater in temperature is the same as that of air temperature.The seawater temperature in the outfall is slightly higher than that in the bay in the time of spring and summer,and reverses in autumn and winter.The average salinity of seawater is 25.6 in spring,21.2 in summer,26.3 in autumn and 30.3 in winter,and shows decline in the order of winter,autumn,spring and summer, but its daily difference in each season is oppositional.The pH value of seawater in average is 8.03 in spring,8.32 in summer,8.18 in autumn and 8.18 in winter, and has great daily difference in spring and summer,and small daily difference in autumn and winter.It is suggested that Lianzhou Bay is favor to the sea farming such as penaeid and clam. |
