| 摘 要： | 研究了在两次台风和一次暴雨期间及随后的恢复期内，厦门湾表层海水盐度、pH、溶解氧以及COD的变化特征。结果表明，台风暴雨期间两站位盐度、pH和溶解氧呈下降趋势而COD则正好相反。随后几日这些参数逐渐回落到风雨前的水平。对影响这些参数变化的机制进行了初步探讨。

| Abstract: | Variation of salinity, pH, dissolved oxygen and COD in Jiulongjiang Estuary and Western Xiamen Harbour were studied during two typhoon process (9810# and Bilis) and one rainstorm process. The results indicated that salinity, pH and dissolved oxygen in both stations showed a decrease tendency during the typhoon or rainstorm process, while COD increased during the same period. They gradually recovered to pre typhoon or pre rainstorm levels in subsequent several days. The factors controlling variation of these parameters were discussed. |
