土地质量地球化学调查成果在判定土壤盐渍化、沙化中的应用

Application of land quality geochemical survey in soil salinization and desertification

依据临夏地区土地质量地球化学调查成果,以与研究区土壤盐渍化指示元素为研究对象,通过元素含量变化和元素间的相关关系,判断研究区盐渍化、沙化土壤分布范围。利用本次调查成果对研究区做出了土壤环境安全现状预警。

Based on the results of land quality geochemical survey in Linxia area,the distribution range of salinized and deserted soil in the study area was judged by taking the indicator elements of soil salinization in the study area as the research object and studying the changes of element content and the correlation between elements.This paper made an early warning for the status of soil environmental security in the study area based on the survey result.
