基于最近5年的调查监测数据，利用内梅罗污染指数法和综合营养状态指数法对南宁市南湖水质变化情况及富营养化程度进行综合分析和评价。结果表明，南湖水体受到了不同程度的污染，TP、TN超标严重，是主要污染因子。南湖水质总体上处于Ⅳ～Ⅴ类，即为中污染至重污染，在个别时期出现了严重污染。南湖水体综合营养状态指数大多处于50～70，大部分属于轻度富营养化中度富营养化；综合营养状态指数呈较有规律的波浪式变化，波峰大都出现在每年的5月至10月，波谷大都出现在每年的1月至4月。

The water quality and eutrophication degree of Nanhu Lake in Nanning were com- prehensively analyzed and evaluated by the Nemerow Pollution Indexes and Comprehensive Trophic Level Indexes, based on the monitoring data of water quality in the period of 2007- 2011. The results showed that the water was polluted in different degrees in Nanhu Lake. The total nitrogen and total phosphorus, as the main pollution factors, were highly over the standards. The water quality of Nanhu Lake was in the degree of IV and V , which was mod- erate and heavy pollution with sometime severe contamination, respectively. Comprehensive Trophic Level Index values were mostly between fifty and seventy, which belonged in the levels of light eutrophication and moderate eutrophication. Comprehensive Trophic Level In- dex values were appeared in a regular wavy variation. The wave peaks appeared from May to October and the wave troughs from January to April.
