摘要:
以1984—1985年海岸带调查资料为基础,讨论了辽宁省海岸带水域的化学要素(DO,pH,盐度、磷酸盐)的分布规律。其动态分布变化规律表明,四种要素的含量与季节的变化有关;通过与1959年海洋调查资料对比可知,四种要素的时空分布没有显著的变化,其含量都处于海水正常浓度水平。在正常潮流水动力作用下,现存的时空分布不会出现较大的改变,即各要素含量梯度不会有明显改变,能够保持稳定的生态环境。
Abstract:
Based on the results of investigation in 1984-1985, the distribution of chemical factors in waters of Liaoning coastal zone, such as DO, pH, salinity and nutrients (PO43--P), are discussed. The variation of dynamic characteristics shows that the four factors changed with the seasons.Compared with the data of 1959, the results indicate that the four factors were still at the same levels in concentration and gradient, which means that the ecological environment was stable during the period under conditions of normal tidal dynamics.
