系统动力学在太原盆地重金属地球化学预警模型中的应用

APPLICATION OF SYSTEM DYNAMICS TO HEAVY METAL PREWARNING MODEL FOR TAIYUAN BASIN,SHANXI PROVINCE

系统动力学是一门研究信息反馈系统的科学。以太原盆地土壤重金属元素背景值为评价标准,对太原盆地重金属元素数据进行分析,利用系统动力学软件(Vensim PLE)建立重金属系统动力学模型,结合地质累积指数方法对As,Ni,Cr,Zn,Cu,Pb,Hg,Cd等8种重金属元素的累积进行预测,并对结果进行了有效的分析。

System dynamics is the science of research information feedback system. Taking the element background value of heavy metal in soil of Taiyuan basin as the evaluation criteria the heavy metal data of the Taiyuan basin are analyzed. Based on this foundation system dynamics＇ software （Vensim PLE） is adopted to establish the heavy metal system dynamics model. Then combining with the Geoaccumulation Index method forecast is made to the accumulation of the eight heavy metals： As, Ni, Cr, Zn, Cu, Pb, Hg, Cd with effective result.
