| 摘 要： | 对重庆市主城区的8个备用水源（水库）进行了富营养化调查,结果表明,调查水库水体中CODMn浓度为3.93-8.13 mg/L,TN浓度为0.778-2.86 mg/L,TP为0.039-0.067 mg/L,Chla含量高,部分水库出现＂水华＂现象;沉积物中TN浓度为0.940-1.898 g/kg,TP浓度为486.6-691.0 mg/kg,水体中TN、TP均超过发生水体富营养化含量标准。采用综合营养状态指数法对水体营养指标进行富营养化评价,其中中营养水平的水库1座,7座水库达到富营养化水平。

| Abstract: | The eutrophication of 8 spare water resources in the main urban area of Chongqing was studied.The results showed that the values of CODMn,TN,TP of the drinking water resources were 3.93-8.13,0.778-2.86,0.039-0.067 mg/L respectively.The concentrations of TN and TP in these spare resources were up to eutrophic level.Concentration of TN and TP in sediment ranged from 0.940-1.898,486.6-691.0 mg/kg respectively.The eutrophic state of drinking water resources was evaluated by the comprehensive nutritive index.7 r... |
