以选自东部平原3种不同类型8个浅水湖泊的18个表层沉积物样品为研究对象,运用分级提取法,研究了沉积物中有机磷(OP)质量分数、形态及其分布状况,并探讨了OP组分与湖泊富营养化的关系.结果表明:东部平原湖泊沉积物中w(OP)为65.2-539.2 mg/kg,占w(TP)的19.9%-40.6%,污染程度高的沉积物w(OP)高于污染程度较轻的沉积物.沉积物中各形态有机磷主要以中活性有机磷(MLOP)与非活性有机磷(NLOP)为主,不同类型湖泊沉积物中各形态w(OP)顺序均为城市湖泊>大型养殖型湖泊>大型自然湖泊,城市湖泊与养殖型湖泊以NLOP为主,其相对含量达到50%以上;而大型自然湖泊以生物有效性有机磷(LOP+MLOP)为主,其相对含量为54....

Eighteen surface sediment samples taken from eight shallow lakes belonging to three different types in the eastern plain region of China were chosen to investigate their contents, forms and distribution characteristics of organic phosphorus （OP）, The relationships between the OP fractions in sediments and their lake eutrophication were also discussed. The results showed that the contents of OP ranged from 65.2 to 539.2 mg/kg, accounting for 19.9% to 40. 6% of w（TP）, which were higher in the heavily polluted sediments than those in the light...
