摘　　要：对重庆市都市圈6座水库的监测结果表明,所有调查的水库均具备了产生富营养化的条件。各水库Chla值范围为4.62～36.40mg/m3;TP范围为0.012～0.323mg/L;TN范围为0.005～5.94mg/L;SD范围为0.48～1.95m;CODMn范围为1.24～7.03mg/L。3种评价方法的相关性较好,综合营养状态指数法可作为评价水库富营养化的统一方法。评价结果:5座大中型水库中,达到重度富营养化的1座;轻度富营养化的2座;中营养水平的2座。这表明都市圈内大中型水库的富营养化程度已经相当严重。An investigation of the 6 large and medium sized reservoirs in Chongqing city zone was carried out and has revealed that concentration of chlorophyll-a, total P(TP), total N(TN), see chi disk depth and COD_(Mn) are ranged from 4.62～(36.40mg/m^3), 0.012～0.323mg/L, 0.005～5.94mg/L, 0.48～(1.95m), 1.24～7.03mg/L.There is significant correlation among the 3 methods. Evaluation with the methods of synthesis index of nutrition state, 1 of 5 reservoirs evaluated are hyper eutropher, 2 are light eutropher, 2 are mesotropher. The eutrophication of the reservoirs in Chongqing city zone is more and more serious.
