摘　　要：根据2001年5月、7月和9月对兴凯湖水域营养盐(NH4+-N、NO3--N、NO2--N和PO43--P)含量的监测结果,分析讨论了其含量变化特征,并利用富营养化评价模式,评价了兴凯湖的潜在性富营养化程度。结果表明,兴凯湖水域水体中的氮、磷营养盐含量随养殖进程呈现不同的季节变化规律,兴凯湖水域N/P值的平均值为19.57,表明兴凯湖水体缺磷,春季以磷为浮游植物繁殖生长的限制因子。潜在性富营养化评价结果为:春、夏、秋季节均处于富营养型水平,表明兴凯湖水域的营养水平较高,水质质量良好。On the basis of investigation data in May,July and September of 2001, variation characteristics of inorganic nitrogen （NH^4＋-N,NO^3--N, NO^2--N） and phosphorus（PO4^3-P）of water in Xinkai Lake were analyzed. The eutrophication degree of water in Xinkai Lake was assessed with the potential eutrophication assessment model. The results showed that the contents of inorganic nitrogen and phoshorus varied with seasons. The annual average value of N/P was 19.57, indicating that phosphorus was deficient of waters in Xinkaihu Lake. Assessment on potential eutrophication revealed that the water quality was rich nutrient in spring, summer and autumn, and showed that nutrient levels were high and water quality was good in Xinkai Lake.
