山东省17市土壤地球化学背景值

Soil Geochemical Background Value of 17 Cities in Shandong Province

摘要:

近20年来，利用财政资金，通过山东省黄河下游流域生态地球化学调查等4个项目，全面完成了山东省1∶25万土地质量地球化学调查与评价。该文以表层土壤Ag，As，Au，B等54项指标地球化学调查数据为基础，分行政区域，统计并研究了全省17市表层土壤地球化学参数及其特征，厘定了山东省17市土壤地球化学背景值，并与全国、全省背景值进行对比，分析了其差异性。

Abstract:

In the past 20 years, through four projects, such as ecogeochemical survey in the lower reaches of the Yellow River basin in Shandong Province, land quality geochemical survey and evaluation with the scale of the 1 : 250000 in Shandong province have been completed with financial funds. Based on geochemical survey data of 54 indexes, such as Ag, As, Au and B in surface soil, geochemical parameters and characteristics of surface soil in 17 cities of Shandong province have been studied by administrative region statistics. The geochemical background values of 17 cities of Shandong province have been determined. Comparing with those of the whole country and province, their differences have been analyzed.
