以西湖不同湖区（北里湖、外湖、西里湖、茅家埠）2012年的逐月监测资料为基础，分析了西湖不同湖区氮磷营养盐以及浮游植物的时空变化特征，并采用综合营养状态指数法，对不同湖区富营养化现状进行了评价。结果表明，氮磷营养盐及浮游植物随时间和空间的不同呈现不同的变化规律。受引水及水生生态系统的影响，西湖水域茅家埠和西里湖自我修复能力较强，水质明显优于北里湖和外湖，全年稳定地处在中营养水平，北里湖和外湖总体处于轻度富营养化，季节变化明显，夏秋季节营养值数明显高于秋冬季节。相关性分析表明，北里湖、外湖、茅家埠三个湖区的综合营养指数与叶绿素a、总磷、水温有显著的正相关关系，西里湖由于受引水影响较大，其综合营养值数与各营养因子及环境因子都没有明显的相关性。

Based on the monthly monitoring data in different areas of West Lake (Beili,Waihu,Maojiabu,Xili) in 2012,temporal and spatial distributions of nitrogen,phosphorus and phytoplankton were analyzed.The eutrophi-cation status was assessed using comprehensive nutrition state index (TLI ).The study showed different variation laws for phytoplankton,inorganic nitrogen,and phosphate over time and space.Because of the influence of water inflow and aquatic ecosystem,Maojiabu and Xili were found to be more capable of self rehabilitation than Beili and Waihu.Therefore,the water quality in Maojiabu and Xili turned out to be better and more stable than that of the other two sites.On the whole,Maojiabu and Xili were mesotropher throughout the whole year of 2012.Beili and Wai were light eutropher.Their seasonal variation trend was quite obvious.The correlation analysis showed that TLI was significantly correlated with Chlorophyll a,total-phosphorus,and water temperature in Beili,Wai and Mao-jiabu.Due to the impact of water diversion system,the TLI and nutrients and environmental factors seemed not?correlated in Xili.
