摘　　要：基于浙江省淳安县1∶25万多目标地球化学调查获取的表、深土壤地球化学数据,本文采用X射线荧光光谱法(XRF)、电感耦合等离子体质谱法(ICP-MS)进行统计分析,获得淳安县土壤54种指标的地球化学基准值和背景值,明确其分布特征。与全国相比,调查区土壤地球化学基准值总体偏高,而Na_(2)O、CaO偏低。深、表土壤方面,元素地球化学分布和分配表现出较大差异。山地丘陵区土壤中元素的分布与成土母质、土壤类型关系密切,成土母质以泥页岩、砂(砾)质岩类风化物和灰岩、白云岩类风化物为主,其中,泥页岩、砂(砾)质岩类风化物占调查区面积的较大比例,该区背景与全区土壤背景基本一致。Based on the surface and deep soil geochemical data obtained from the 1∶5250000 multi-target geochemical survey in Chun’an County,Zhejiang Province,this paper uses X-ray fluorescence spectroscopy(XRF)and inductively coupled plasma mass spectrometry(ICP-MS)for statistical analysis,so as to obtain the geochemical reference values and background values of 54 soil indicators in Chun’an County,and clarify their distribution characteristics.Compared with the whole state,the reference value of soil geochemistry in the survey area is generally higher,while Na_(2)O and CaO are lower.In deep and surface soils,the geochemical distribution and distribution of elements show great differences.In the soil of mountainous and hilly areas,the distribution of elements is closely related to the parent material and soil type,the soil-forming parent material is mainly shale,sand(gravel)weathering materials,limestone and dolomite weathering materials,among them,shale and sand(gravel)weathering materials account for a large proportion of the survey area,and the background of this area is basically the same as the soil background of the whole area.
