宜宾市翠屏区宋家乡土壤地球化学质量评价及意义

An Appraisal of Soil Environmental Geochemistry Quality in Sung Home Town of Cuiping Area,Yibin City,China and Its Meaning

在表层土壤系统采样调查的基础上,进行了相关的灌溉水、饮用水以及土壤有机物和大气降尘等的测试,分析结果显示,宜宾市翠屏区宋家乡土壤存在重金属元素超标趋势,尤其是镉。采用地质累积指数法和污染程度分析对翠屏区宋家乡地区土壤质量进行了评价和分析,为该区土壤资源、环境评价和农业经济发展规划提供了实用地球化学信息。

In the surface layer water, the tap water as well as soil system sampling investig foundation, the correlation the irrigation the soil organic matter and the atmospheric falling tested. The analysis results show that the soil, in Song home town of Cuiping aera, metallic element exceeding the allowed figure tendency, in particular cadmium （Cd geological accumulation exponential method and the pollution degree analysis carries dust and so on were Yibin city town exist ） element. Using the on the appraisal and the analysis to Song home town area soil quality, for this area soil resources, the environment appraisal and the agricultural economy development plan has provided the practical geochemistry information.
