    The evaluation of soil elements in topsoil of the sewage irrigation area in Shijiazhuang

    • 摘要: 提要:本文参照土壤质量内涵的三个方面,对石家庄污灌区表层土壤元素进行了评价。研究认为,反映土壤肥力质量的肥力元素大部分处于丰富或适宜状态,只有Mo、Co、碱解氮、有效Mo等处于相对缺乏状态;反映土壤环境质量的重金属元素含量都低于《土壤环境质量标准》(GB-15618-95)中二级标准限值,其中Cu、Ni、As、Hg、Pb元素100%达到了土壤一级环境质量标准,同时通过对研究区重金属元素的形态分析认为:Cd的生物有效性和潜在危害性较大,是研究区最具有生态危害的重金属;反映土壤健康质量的土壤元素F处于丰富或适宜状态,I处于相对缺乏状态。

       

      Abstract: Abstract:In this paper soil elements in topsoil of the sewage irrigation area in Shijiazhuang are evaluated, with three aspects of soil quality taken into account. Studies suggest that elements reflecting soil fertility quality are in a rich or desirable state except for Mo, Co, alkali-hydrolyzable N, available phosphorus and effective Mo which are relatively deficient. The concentrations of heavy metal elements which can reflect the soil environment quality are all below the secondary standard limits in "soil environmental quality standard" (GB-15618-95), with the concentrations of Cu, Ni, As, Hg, Pb completely reaching the senior standard. A morphological analysis of heavy metal elements show that the bio-availability and potential harmfulness of Cd are relatively serious and hence this element may be the most ecologically harmful element in the study area. Among the elements which reflect the quality of soil health, F is in abundant or desirable state while I is in relatively deficient state.
