摘　　要：探讨了梅山岛附近海域冬、夏季水化学要素的分布特征及其成因,并根据海水水质标准,对该海域的水质进行了评价。结果表明,该海域各化学要素含量均为冬季高于夏季(氧饱和度除外),水质质量夏季比冬季好,氮含量偏高,只要严格控制工业和生活污水的超标排放,同时防止水土流失,减少陆源对氮含量的影响,那么该海域冬、夏季水质就能达(?)类海水水质标准,适宜海水养殖。The distribution and cause of the hydrochemical composition, O2, pH, PO4-P, SiO3-Si, NO3-N and NO2-N, in the vicinity of the Meishan Island in winter and summer have been studied and water quality has been assessed according to the standard proclaimed by the state. The result shows that the contents of the composition, except that of oxygen saturation degree, were higher in winter than summer. The water quality wae better in summer than winter. The content of nitrogen was slingtly high. So long as the drainage effluent was controlled strictly and soil erosion on the land was prevented to lessen the nitrogen flux into the sea, the water puality in summer and winter will be up to the first grade of the state standard, thus suitable for marine aquaculture.
