| 摘 要： | 经过2年13次采样分析、综合评估,结果表明:宁夏阅海湖目前的理化、生物状况已呈现出规律性中度污染—重度污染—中度污染的年度变化。部分重点理化、生物指标年平均为:透明度63.9 cm,pH 8.8,DO 6.07 mg/L,COD 16.84 mg/L,浮游生物量12.36 mg/L。结合生物多样性分析和相关国标水质分类标准,把阅海湖整体定位于中度偏重营养盐污染的藻性湖泊类型,生态系统脆弱。 |

| Abstract: | After sampling 13 times in 2 years of Yuehai Lake,the data was studied and comprehensive evaluated,as well as the physicochemical and biological conditions.The results showed: at present,there was a regular change of pollution with moderate-heavy-moderate yearly.Part of major physicochemical and biological parameters of annual average was transparence 63.9 cm,pH 8.8 DO 6.07 mg/L,COD 16.84 mg/L and biomass of plankton 12.36 mg/L.Combined with biodiversity analysis and national standard of water quality classification,Yuehai Lake was dominated as algae lake with moderate prefer to nutrient pollution as a whole,fragile ecosystem. |
