摘　　要：为了深入了解哈尔滨市城市河道沉积物硫污染情况,以哈尔滨三大内河之一——信义沟为例,对其沉积物中酸挥发性硫化物(AVS)的水平和垂直分布进行研究。结果表明,河道所在地的气温、酸雨沉降量以及河道水体-沉积物的氧化还原状态对表层沉积物中AVS的累积具有十分重要的影响;在垂直分布中,沉积物中AVS随深度增加呈现出不同的变化趋势,表明了信义沟河道各区域沉积物稳定性不同。在这一研究结果的基础上,将信义沟沉积物中AVS含量随深度的变化与有机质含量进行线性回归分析发现,信义沟沉积物中AVS与有机质呈正相关,说明了对于北方城市河道沉积物,有机质含量对AVS同样具有重要影响。In order to have an in-depth understanding about the sulfide pollution conditions of riverway sediment in Harbin,Xinyi riverway,one of the three largest rivers in Harbin,was exemplified to study its acid-volatile sulfides（AVS） level and horizontal distribution.Results showed that the accumulation of AVS in surface sediments was greatly influenced by the regional temperature,acid rainfall and the redox state of the riverway;the distribution of AVS in sediments showed different variation tendency with the increasing depth,indicating that the sediments at each parts of Xinyi riverway showed different stability.Based on the research results,a linear regression analysis was conducted,it was found out that the AVS content in Xinyi riverway sediments was positively correlated with the organic content,proving that the content of organic contents produced important impact on the AVS content in the riverways of North China.
