摘要
根据田庄水库的自然地理和水文特征,作者选择7个监测点,定量监测了水库和入库河段的水质分布特征,并采用卡森水质营养状态指数法和特里指数法对水库富营养化情况进行综合评价。研究结果表明,在所有监测点中NH4+-N、TN、TP均严重超标,田庄水库现状水体已经达到轻度富营养化水平;从入库、库区至出库的表层水体中,TP的浓度逐渐降低;除DO外,在水库的垂直剖面上,其他指标浓度随深度的增加呈增加的趋势。
According to the characters of physical geography and hydrology of Tianzhuang Reservoir, 7 sites were selected for monitoring the distributive characteristics of water quality in Tianzhuang Reservoir and its input stream. And the level of eutrophication in Tianzhuang Reservoir＇s water was also assessed by Carlson TSIs and TLIs.The results showed that the concentrations of NH4^＋ -N, TN, TP were much higher than the values of relevant standard at all monitoring sites, and the water quality has become eutrophication lighdy in Tianzhuang Reservoir.And the concentrations of TP in surface water from input stream to reservoir decrease gradually.The concentrations of all the indexes but DO increase with increase of depth vertically.
