河北井陉地区耕地表层土壤质量地球化学评价

    Geochemical assessment of the surface soil quality of cultivated land in Jingxing area, Hebei Province

    • 摘要: 土壤质量地球化学评价是农业种植等合理利用土地资源的重要参考依据. 井陉地区作为石家庄市生态涵养区,农业是其主要的第一产业. 以井陉地区作为研究区,采集表层土壤样品158件,对土壤地球化学特征、养分元素丰缺性、环境地球质量和综合等级进行分析评价. 结果显示,土壤质量综合等级以一等和二等为主,表明研究区土壤环境地球化学等级为清洁,土壤养分地区化学等级为较丰富,为合理利用土地资源和农作物种植结构改革提供了基础依据.

       

      Abstract: Soil geochemical assessment serves as an important reference for the rational utilization of land resources in agricultural planting. As an ecological conservation area of Shijiazhuang City, Jingxing County relies on agriculture as its primary industry. Taking Jingxing area as the study object, 158 surface soil samples are collected to analyze and evaluate the soil geochemical characteristics, abundance and deficiency of nutrient elements, environmental geochemistry and comprehensive grade. The results show that the comprehensive soil quality classification is predominantly Class Ⅰ and Ⅱ, indicating that the environmental geochemical grade of soil in the study area is clean, while the geochemical grade of soil nutrients is relatively abundant, which provides a fundamental basis for the rational utilization of land resources and reform of crops planting structure.
