    摘要:

    土壤是重要的自然资源之一,与人们的生活息息相关。笔者等基于任丘市1∶5万比例尺土地质量地球化学调查成果,依据相关标准和规范,对研究区土壤植物生长必需营养元素、重金属环境质量和土壤健康质量的元素进行了评价,为研究区生态环境保护、土地利用规划、特色农业开发、高标准农田建设等提供了科学依据。评价结果表明:① 土壤养分元素磷、钾、三氧化二铁处于丰富或中等状态,有机质、氮、铜、钼等元素处于较缺乏状态,有效态中有效锰、有效铁较缺乏;土壤总体处于碱性,偏碱性,元素有效态含量与其全量做相关分析得出具有一定的相关性,土壤pH从碱性到强碱性,Cu、Mn、Zn、K元素有效态与其全量的相关性减弱,B、P元素有效态与全量的相关性增强;②重金属元素单因子指数法评价,除一个样品Ni元素和两个样品Zn元素超过农用地土壤筛选值外,Cu、Pb、As、Cd、Cr、Hg元素均符合农用地土壤污染风险管控标准;研究区尼梅罗综合污染指数全部小于0. 7,说明全部达到了一级水平;研究区8种重金属元素全部符合无公害蔬菜产地的环境质量标准;除个别Cd元素和Pb元素样品不达标外,其他元素水平全部符合土壤《绿色食品产地环境质量标准》;③反映土壤健康质量的元素F和Se元素整体处于缺乏—较缺乏状态,I元素整体处于适中状态。

    Abstract:

    As one of the crucial natural resources, soil is tightly associated with people’s daily life. Based on the 1∶50000 scale of geochemical survey results in Renqiu City, Hebei Province, the writers evaluated the soil quality of the study area, aiming to provide scientific basis for the ecological environment protection, land use planning, characteristic agriculture development, high- standard farmland construction and else over here. Methods: According to the relevant standards and specifications, this paper assesses the nutrient elements essential for soil plant growth, the environmental quality of heavy metals and the factors of soil health quality in the study area. By means of Microsoft Excel, ArcGIS, SPSS and other data- processing softwares, we conduct the data distribution test, parameter calculation and map plotting. Moreover, single factor index method, Nemerow integrated pollution index method, correlation analysis method and else are adopted for further data processing and analysis. Results: (1) Soil nutrient elements like phosphorus, potassium and ferric oxide were found all in a rich or medium state, while organic matter, nitrogen, copper, molybdenum and other elements were in a relatively deficient state, whereas available manganese and available iron in the available state were relatively insufficient. (2) The soil was identified as being generally and slightly alkaline, with the analysis between the effective state content of elements and their total amount showing a certain correlation. The soil’s pH- value changed from alkaline to strongly alkaline, the correlations between the effective states of Cu, Mn, Zn, K elements and their total amounts all decreased, while those between the effective states of B, P elements and their total amounts both increased. (3) According to the evaluation of heavy metal elements by single factor index method, except for one sample of Ni and two samples of Zn exceeding the screening value of agricultural land soil, the elements of Cu, Pb, As, Cd, Cr, Hg all met the control standards of agricultural soil pollution risks. The Nemerow integrated pollution index in the study area was assessed to be all under 0. 7, indicating that all of them have reached the first- class level. The contents of eight heavy metal elements in the study area all satisfied the environmental quality standards of pollution- free vegetables’ origins, Except for some Cd and Pb samples that failed to meet the standard, the contents of other elements wholly achieved the “Environmental Quality Standard of the Sources of the Green Food”. (4) As the indicators of soils’ health quality, the elements of F and Se were found generally in the state of lack to relatively lack, while the element I was in a moderate state as a whole. Conclusions: The geochemical evaluation criteria of soil quality, single factor index method, Nemerow integrated pollution index method and correlation analysis method have all been effectively applied to the geochemical assessment of soil elements in Renqiu City, Hebei Province, which provided a scientific basis for its land use planning, characteristic agriculture development and high- standard farmland construction.
