摘要
土壤是人类赖以生存的基础,土壤中各种化学元素的含量与人类生活环境息息相关,因此对土壤中化学元素进行异常查证是十分必要的,不仅有助于进行环境评价,而且能为环境治理提供有力的依据。本文主要研究重金属元素在表层土壤中的传播特征,建立相应的数学模型,给出求解方法。
Soil is the base for human being survival.The contents of chemical elements in soil are closely linked with the environment.Therefore the investigation on anomaly of geological environment for urban soil is necessary.This administers to evaluate urban environmental quality,and provides convincing arguments for fathering environment.In this paper,the propagation character of heavy metals contamination in urban topsoil is studied.A mathematical model and solving method are presented.
