| 摘 要： | 根据2009年春夏秋冬4个季节调查资料，分析钦州湾表层海水温度、盐度及pH值的季节变化和分布特征。结果表明：钦州湾海水平均温度春季20．4℃，夏季30．1℃，秋季16．0℃，冬季14．6℃，变化特征与气温的季节变化相同，空间分布为夏秋季河口区的水温都略高于湾口区，而春冬季则相反。海水平均盐度春季20．067，夏季17．975，秋季23．864，冬季23．660，表现为秋季〉冬季〉春季〉夏季，各季节空间分布总体表现为河口区低，湾口区高的趋势。海水pH平均值春季7．82，夏季8．11，秋季8．01，冬季8．10，全年空间分布高值区均出现在大风江口外海域。钦州湾海水比较适宜大蚝、对虾、文蛤等广温广盐性品种的海水养殖。

| Abstract: | The seasonal variation and distribution of temperature,salinity and pH value of surface seawater are analyzed according to the measurements of seawater in Qinzhou Bay,Guangxi,and Southern China in 2009.The results show that the average seawater temperature is 20.4 °C in spring,30.1 °C in summer,16.0 °C in autumn,14.6 °C in winter.The seasonal variation of seawater temperature is the same as that of air temperature.The seawater temperature in the estuary is slightly higher than that in the bay in summer and autumn,and reverses in spring and winter.The average salinity is 20.067 in spring,17.975 in summer,23.864 in autumn,23.660 in winter,and shows decline in the order of autumn,winter,spring,summer.The spatial distributions of these seasons display high salinity in the estuary and low salinity in the bay.The average value of pH in the surface seawater is 7.82 in spring,8.11 in summer,8.01 in autumn,and 8.10 in winter.The high pH values appeared in the outer area of the Wind River for four seasons.It is suggested that Qinzhou Bay is favor to mariculture such as oyster,penaeid and clam. |
