山东省茌平县土壤元素地球化学特征与质量评价

Geochemical Characteristics and Quality Evaluation of Soil Elements in Chiping County in Shandong Province

摘要:

以茌平县土壤为研究对象，通过系统的地球化学调查，获取了土壤20余项指标含量数据；在此基础上计算了茌平县土壤中背景值和基准值等系列地球化学参数，圈定地球化学异常区，评价了土壤养分和环境地球化学等级、土壤质量地球化学综合等级。结果表明，与山东省土壤背景值平均值相比，茌平县土壤中K、Mn、Pb、V、Mo、I等元素偏低，而有机质、As、Cd、Hg、B等元素偏高。调查区7类异常区域均有分布；土壤质量综合评价以优质等级为主，约占全区面积的73.96%，良好等级约占全区面积的24.67%。

Abstract:

Taking the soil in Chiping county as the research object, more than 20 index content data of soil have been obtained through systematic geochemical investigation. Based on geochemical parameters and geochemical grade of soil, geochemical grade of soil has been calculated. Comparing with the average value of soil background value in Shandong province, the elements, such as K, Mn, Pb, V, Mo and I in the soil of Chiping county are lower, while the elements, such as organic matter, As, Cd, Hg and B are higher; Seven types of abnormal areas are distributed in the survey area. The comprehensive evaluation of soil quality is mainly high quality grade, and accounts for about 73.96% of the whole region, and the good grade accounts for about 24.67%.
