宜宾江安桐梓镇土地整理区耕地土壤重金属含量及评价

摘要

土壤重金属污染问题已成为环境问题中备受关注的一个焦点,而重金属污染严重的土壤会影响到农作物产量的质量和安全性,进而对人类自身健康造成一定危害.这里以地质地球化学调查填图为基础,以土壤采样分析成果为依据,以地球化学研究方法为手段,查明了桐梓镇土地整理区耕地土壤重金属元素含量特征和分布现状,为当地无公害食品等农业生产基地优选,农业种植结构调整等方面,提供了翔实的地球化学方面的基础资料.%Soil heavy metal pollution in the environment becomes a focus of concern, and heavy metal pollution of soil will affect the crop yield quality and safety and cause some harm health of human beings. The paper introduce the geochemical research methods to identify Tongzi town land consolidation area heavy metal content of arable soil characteristics and distribution of the current conditions, and for local no pollution offood optimization of agricultural production bases of agricultural planting structure adjustment with picture - based, results - based soil sampling and analysis as a means, which has provided the basic geochemical information.
