摘　　要：通过2009年8月和12月对崇明岛2条市级河道和6条县级河道中营养状态特征因子展开调查,结果表明,各因子除高锰酸盐指数外,具有明显的季节性差异。利用综合营养状态指数对崇明各河道进行富营养化评价,结果表明目前崇明大部分河道水体已发生富营养化。针对河道营养物质的来源主要与城镇、农村污水以及农业化肥的施加有关,提出应结合不同地区的特点采取相应的措施。An investigation is conducted to survey the nutrition condition character factor of 2 city-level rivers and 6 county-level rivers in Chongming Island in August and December of 2009. The result shows the factors are seasonal varied significantly, except for Permanganate index. The eutrophication assessment of rivers in Chongming Island by comprehensive nutrition index indicates that eutrophication occurs in most rivers in Chongming Island. Source of eutrophication material is related to the urban and rural sewage, as well as agricultural fertilizers. It proposes that measures should be taken according to local condition.
