摘要：20世纪90年代初,浙江省地球物球地球化学勘查院先后在杭嘉湖平原区、宁绍平原区、温黄平原区、金衢盆地等四大块平原区开展生态环境地球化学调查，获得了数以万计的定量分析数据，编绘了各类相关图件及说明书。将数以万计的分析数据，经技术处理，最终取得了全省土壤中元素背景含量。

BACKGROUND CHARACTERISTICS OF SOIL ELEMENTS IN FOUR PLAINS OF ZHEJIANG PROVINCE

At the beginning of the 1990 s, the authors carried out ecological environment geochemical investigation in Hangjiahu plain, Ningshao plain, Jinqu Basin and Jinqu plain and, as a result, obtained thousands of analytical data and compiled various kinds of relevant maps and manuals. On the basis of these materials and through technical management,the authors finally acquired threshold contents of soil elements in the whole province.
