摘　　要：为了解投饵型网箱养殖对水库沉积环境硫化物的影响,本文研究了樟湖库湾网箱养殖水域底质硫化物含量的空间分布、季节变化和污染状况。结果表明,硫化物含量范围在0.5735~2.3642μmol·g^(-1)之间,与开放型湖泊及河流较接近;网箱养殖区高于非养殖区,夏季相差倍数和冬季相差倍数分别介于1.67~2.95和1.34~1.83之间,网箱养殖活动对底质硫化物的积累具有一定影响;季节含量变化上表现为夏季>春季>秋季>冬季,网箱养殖区硫化物含量季节变化规律与网箱养殖活动相关;闽江流域硫化物含量本底值较高,沉积环境硫化物的积累更多受外来面源污染的影响。In order to understand the impact of sulfide at feeding cage farming area in reservoir,the spatial distribution,seasonal change and pollution assessment of sulfide in the surface sediments at cage farming area of Zhanghu reservoir bay in Shuikou reservoir were studied.The results indicated that the sulfide concentrations ranged from 0.5735~2.3642μmol·g^(-1),which was approaching the strength of open lakes and rivers.Compared with the properties of sulfide contents from inside and outside the cage area,the previous one was relatively high,and the multiple of difference varied from 1.67 to 2.95 between summer and winter,which were higher than those from 1.34 to 1.83,the results showed that cage culture activities had a certain impact on the accumulation of sediment sulfide.It was found that the seasonal variation of sulfide were in the order of summer>spring>autumn>winter,which showed that the change law was related to cage culture activities.The background value of sulfide content was high in Min River basin,indicating that the accumulation of sulfide in the sediments was more affected by the external non-point source pollution.
