| 摘 要： | 以浙江省农业地质环境调查取得的区域地球化学资料(2002—2004年)为依据,遵循地球化学背景值的基本概念,根据成土母质类型将土壤地球化学基准值划分成13个统计单元,土壤环境背景值以浙北杭嘉湖与宁绍平原、浙东沿海温黄与温瑞平原、浙中金衢盆地区统计单元,在反复剔除异常数据后,获得了52种元素(氧化物)的平均值、标准离差和变异系数,为区域土壤环境质量标准的制订、土壤污染评价和治理修复提供了重要的地球化学依据。

| Abstract: | The soil geochemical baseline values for main agricultural areas of Zhejiang Province are divided into 13 statistical units and the soil environmental background values are divided into three geographical statistical units,i.e.the Hangzhou-Jiaxing-Huzhou and Ningbo-Shaoxing plains of northern Zhejiang,coastal Wenzhou-Huangyan and Wen-Rui plains of eastern Zhejiang and Jinhua-Quzhou basin of central Zhejiang.The division is made according to the types of soil-forming parent materials,based on the regional geochemical data obtained during agro-geological environmental survey in Zhejiang Province(2002-2004)and following the basic concept of geochemical background values.The mean values,standard deviations and variation coefficients of 52 elements(oxides)were obtained after eliminating anomalous values repeatedly.The soil geochemical baseline and environmental background values are basic geochemical data for the formulation of regional soil environmental quality standards and assessments and remediation of soil pollution. |
