摘　　要：基于2009年新立城水库的水质调查资料,分析了新立城水库营养盐动态及富营养化特征.结果表明,高锰酸钾指数范围为3.4～8.6mg/L,TN为0.48～1.66mg/L,TP为0.021～0.096mg/L.TN和TP含量均超过水体发生富营养化的临界值.7～9月份的N/P适宜藻类生长.选用修正的Carlson营养状态指数法评价水体营养状态,结果表明,6～9月为富营养水平,其余月份为中营养水平.相关分析表明,温度对Chl-a含量的影响显著.另外,Chl-a与pH、总磷之间的相关性显著,与总氮、溶解氧之间相关性较弱.We analyze the nutrient dynamics and eutrophication features in Xinlicheng reservoir.The variation ranges in CODMn,TN,and TP were 3.4-8.6mg/L,0.48-1.66mg/L,and 0.021-0.096mg/L,respectively.TN and TP concentrations exceeded the threshold for eutmphie state.N/P ratios favored algal growth between July and September.The trophic state of Xinlicheng reservoir was meso-tropher to eutrophic.Significant positive correlations were found between Chlorophyll-a and water temperature,pH,and TP.However low correlations were found between Chlorophyll-a and TN and between Chlorophyll-a and dissolved oxygen.
