摘　　要：通过连续 4年对黄河三角洲 6座水库水环境化学的观测发现 ,水层中总磷 (TP)丰度存在明显的季节波动 ,并与氢离子 (H)或 (和 )氯化物 (Cl)丰度存在显著相关关系 (p<0 .0 1 ,p<0 .0 5) ,但没有发现其随着年度推移的变化规律。根据对 7座 9～ 2 6年不同库龄水库的调查发现 ,随着库龄的增加 ,底泥中沉积的总磷 (DP)显著增加 (p<0 .0 5)The Yellow River Delta lies in the littoral of Bohai Sea, 38°N 118°E. Because of the nutrient-rich inflow by the Yellow River, the reservoirs in this region, with depth from 1.5 to 6.0 meter, often represent either bloom of toxic green-blue algae or that of nuisance submerged-grass in the water. Four years of continuous monthly researches on total phosphorus concentration in water (TP) and other water environmental chemistry factors in 6 reservoirs in Hekou district north to the Yellow River, and twice researches on deposited total phosphorus concentration in sediments (DP) of the 6 reservoirs and another reservoir south to the Huanghe River in the winter of 2002 got the following results: (1) The seasonally fluctuation of TP were correlative significantly with chloride concentration or (and) hydrogen ion concentration (p<0.01 and p<0.05); (2) The four years' fluctuation of TP had no significant tendency as year passing, whereas the DP enhance significantly with reservoir ages (p<0.05); (3) The TP ranging between 0.01mg/L and 0.1mg/L and the DP ranging between 0.9mg/g and 3 mg/g suggested that sediments there had capacity of storing more phosphorus than other lakes researched by other limnologists, because of higher salinity in water and special soil in this region.
