| 摘 要： | 通过对铁山港湾水动力条件及20a(1983~2003年)来水环境因子变化状况的分析,探讨了该湾水体自净能力及其与环境因子之间的关系,结果表明:该湾具有较强的水体自净能力,但其物理净化能力是以潮流的水动力作用影响为主,迳流影响较小,与北海湾和钦州湾有明显差别;其化学净化能力主要体现在溶解氧的含量水平、有机污染物的氧化分解能力、营养盐的形态转化及消减程度上;其生物净化能力则体现在微生物及浮游动植物对有机物的直接降解及间接贡献上,具有贫营养区的水体自净特点。

| Abstract: | After analyzing the hydrodynamic condition and the variations of the water environment factors over the past 20 years(1983-2003) of Tieshangang bay,we tried to find out the relationship between the self-purifying ability and the environment factors of Tieshangang Bay.The results showed that Tishagang Bay had strong self-purifying ability.Its physical purification ability mainly depended on the hydrodynamic action of tidal currents and small contribution of runoffs,which was remarkably different from Beihai Bay and Qingzhou Bay.Its chemical purify ability was mainly reflected in the content level of the dissolved oxygen,the ability of oxidation and decomposition of the organic matter,the form conversion of the nutrient salts and the extent of their dissipation extenuation.However its biological purification ability was reflected in the direct degradation oforganic matters and indirect contribution microorganism and phytoplankton whichpossesses the character of oligotrophic areas. |
