摘要:

参照土壤质量内涵的3个方面,对河北平原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,只有土壤有机质、全氮、全磷、碱解氮、锌、钼、有效钼、有效硼等处于相对缺乏状态,其中有机质、全钼、有效钼缺乏严重;依据《土壤环境质量标准》(GB—15618—95)评价研究区土壤,其结果认为研究区土壤重金属环境质量状况良好,土壤重金属超标率非常低。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:

This paper evaluates the elements of Hebei plain topsoil by referring to the three aspects of soil quality. Study shows that elements reflecting soil fertility quality are in a rich or fitting state, but the other ones including TOC, N, P, alkalihydrolyzable N, Zn, Mo, effective Mo, effective B are insufficient, especially TOC, Mo, effective Mo are deeply lacking. According to Soil Environmental Quality Standard (GB-15618-95), it suggests that the environment of Hebei plain heavy metal elements are favorable, and the exceedingstandard rate of these elements is very low. And the analysis of these heavy metal elements form shows that the bioavailability and potential harmfulness of Cd is much large and it is the most ecologically harmful element in the area. Among the elements which reflect the quality of soil health, F is rich or fitting while I is in relatively lacking state.

Key words: :Hebei plain, soil, heavy metal element, evaluation
