摘要
土壤垂直剖面上物化性质、矿物和化学组成的深入研究,可以提供有关成土母质、成壤演化作用的重要信息,识别人类活动叠加的污染强度和影响深度,为土壤地球化学背景值调查、土壤污染及其生态环境影响的评价、环境地球化学灾害的监控与预警研究提供科学的方法和依据。根据广东珠江三角洲、湖北江汉平原、四川成都盆地部分土壤剖面实测资料,分析研究了土壤化学组成的剖面变化与成土母质类型及组成、土壤成熟度和污染影响的关系,探讨了土壤剖面地球化学特征的地质与环境指示意义,判断分析了土壤受到的污染叠加作用及其影响深度。
Vertical distribution of elements in soil profiles was mainly controlled by their original sediment component, soil geochemical process and pollution. Therefore, analysis of element distribution in soil profiles can provide important information for sediment environment, geochemical process during soil forming and soil contamination. Some soil profiles in Guangdong, Hubei and Sichuan province has been provided. Vertical distribution of some physico-chemical indicators and elements were described. Finally, their geological and environmental interpretation was discussed.
