摘要
针对熊河水库表层沉积物氮、磷及有机物污染状况,开展监测分析。结果显示:熊河水库入库河口和坝前底泥堆积较厚,表层多为松软的黑臭泥,其中坝前淤泥堆积最深;熊河水库沉积物0^-45 cm层总有机碳含量在0.9~3.7%之间,其中0^-10cm的表层有机污染相对较高,坝前有机物污染含量较高且累积最深;沉积物的总氮和总磷含量均较高,但各采样点分布不一致,个别高含量点存在高释放风险。
Monitoring and analysis of nitrogen,phosphorus and organic pollution in the surface sediments of the Xionghe Reservoir.The results show that the sediment at the estuary of the Xionghe Reservoir and the front of the dam is thick,and the surface layer is mostly soft,black and stinky mud.The silt in front of the dam is the deepest.The total organic carbon content in the 0^-45cm layer of the Xionghe Reservoir is between 0.9~3.7%,of which the surface organic pollution of 0^-10cm is relatively high,and the organic matter pollution in front of the dam is high and the accumulation is the deepest;the total nitrogen and total phosphorus contents of the sediments are high,but the distribution of each sampling point is not consistent There is a high release risk at individual high content points.
