| 中文摘要: |
| 2009年7月至2010年5月以叶绿素a、总氮、总磷、高锰酸盐指数和氨氮等为主要水质指标,选用营养状态指数生物指示法对上海市7个周边区的16条农村河道的水环境质量进行了分析和评价。结果表明,所有被调查的河道均已经达到富营养化,按4项主要水质指标评价,16条农村河道已无I类水。秋冬季15条河道总氮含量处于劣Ⅴ类水质,夏季也有10条处在这个水平;总磷含量呈现劣Ⅴ类水的河道在冬季明显较多,达到13条,夏季次之为7条,而秋季大约有9条河的总磷含量处在Ⅲ类水;氨氮含量在春冬季分别有9条和10条河道处在劣Ⅴ类,但夏季有9条河道氨氮处在Ⅲ类或Ⅱ类;河道的高锰酸盐指数全年基本处于Ⅳ类水。调查还发现同一河道在一年中的盐度也有变化,冬季河水的盐度相对较高,最高能达到1.6。科学地分析水体污染状况,采取相应措施加强对农村河道的管理,控制水体的进一步恶化已经到了刻不容缓的地步。 |

| Water quality of 16 of suburban rivers in Shanghai was analysized and evaluated based on main parametern such as Chl. a，TN, TP, CODMn and NH4-N, from September 2009 to May 2010. Comprehensive trophic state index TLI ( ∑) was used to value the water trophic state .The conclusion showed that all of the investigated river channels in Shanghai were eutrophicated. In fall and winter, the total nitrogen content 15 rivers are worse than class V while 10 rivers in summer; The amount of the river channels which showed inferior category V water quality according to the total phosphorus content in winter and in summer is 13 and 7 respectively，compared with that about 7 of the rivers in fall are at class Ⅲ. Ammonia content in spring and winter were separately 9 and 10 rivers at the inferior class V state，9 rivers in summer were in the class Ⅲor class Ⅱ; The annual CODMn index in these rivers were at the water status class Ⅳ .The survey also found that the salinity in the same river changed through the year, in which the salinity reached to maximum 1.6 in winter. It has become a huge urgency to analysis the water pollution scientifically , take appropriate measures to strengthen the management of rural river channels，and avoid further water deterioration. |
