摘　　要：水中的铁是动植物生长必需的微量元素,其含量直接影响水的质量。水生态系统中的铁主要以亚铁和三价铁的形式存在,两种形式之间的平衡以及铁的沉淀和释放取决于许多人为和自然因素。研究区域位于济平干渠末端,通过持续一年对济平干渠总铁和亚铁的含量进行检测,结果表明,济平干渠水中总铁的含量较高,且夏秋季节浓度高于春冬季节,其浓度和形态的季节性变化与水中水温、溶解氧、高锰酸盐指数、pH的含量有关,为济平干渠优化分季节取水提供了依据。Iron in water is a necessary trace element for the growth of plants and animals, and its content directly affects the quality of water. Iron in aquatic ecosystems exists mainly in the form of ferrous and trivalent iron. The balance between the two forms and the precipitation and release of iron depend on many human and natural factors. The study area is located at the end of Jiping trunk canal. The content of total iron and ferrous iron in Jiping trunk canal has been tested for one year. The results show that the content of total iron in the water is high and the concentration in summer and autumn is higher than that in spring and winter. The seasonal variation of the concentration and form of total iron is related to water temperature, dissolved oxygen, permanganate index and pH. It provides a basis for optimizing the seasonal water intake of the Jinping main canal.
