| 摘 要： | 土壤生态地球化学基准值是衡量和评价由人为扰动产生的微观地球化学效应的参比基准。在区域生态地球化学调查、评价以及环境地球化学研究等工作中均具有重要意义。笔者以中国东部平原区的土壤为研究对象．采用切实可行的试验研究方法，提出了土壤生态地球化学基准值，并提供了相应基准值的土壤物质组成信息。进一步研究结果表明，土壤物质组成特性在宏观上控制了基准值的区域性分布特征。

| Abstract: | The soil eco-geochemical baseline is a reference standard for evaluating the induced by artificial disturbance. It has great significance in regional eco-geochemical geochemical micro-effect survey and evaluation and environmental geochemical research. The paper presents the soil eco-geochemical baseline with the soils of alluvial plains in eastern China and by using practical methods of experimental study and provides the information of the soil granularity and material composition related to the baseline. Further study indicates that the features of the soft material composition macroscopically control the regional distribution characteristics of the soft eco- geochemical baseline. |

| Keywords: | eastern plains soft eco-geochemical baseline soft granularity and mineral composition |
