  • 摘要: 为研究底泥中内源性磷释放对城市景观水体富营养化的影响,以西安市曲江南湖为对象,采用底泥磷形态标准测试方法(SMT)分析了磷的赋存形态,通过模拟实验探究了在不同环境条件(温度、pH和溶解氧)下磷形态变化的特征。结果表明:温度升高促进内源磷的释放,在夏季加剧水体富营养化程度;碱性条件有利于磷的释放,增大补给水源可减少底泥释磷量;厌氧环境下底泥释磷量是好氧时的3.96倍;Al-P 和Ca-P较稳定,在酸性条件下会加速其溶解;NH4+-P、 Fe-P 和OrgP受溶解氧、pH和温度影响较大,其吸附与释放能力有明显的差异。
    Abstract: In order to study the effect of endogenous phosphorus release in sediment on eutrophication of urban landscape river,Qujiang South Lake in Xi'an city was chosen as the study object.Phosphorus forms were analyzed using the standard measurement and test(SMT)procedure,and the characteristics of phosphorus forms change were explored by simulation experiment under different environmental conditions which was temperature,pH and dissolved oxygen(DO).The results indicated that the rising temperature promoted phosphorus release so that eutrophication was serious in summer.The alkaline condition was much more propitious to phosphorus release,while increasing of water-supply was adverse.The release amount of phosphorus in anaerobic environment was 3.96 times higher than that in aerobic environment.The Al-P and Ca-P were dissolved quickly under acidic conditions.The NH4-P,Fe-P and Org-P were greatly influenced by DO,pH and temperature,and its adsorption and release capacity had significant differences.
