The main content of the study includes: the policy variables are classified into two types, which are continuous policy variable and discrete policy variable, and the two variable is analyzed respectively; as to the continuous policy variable, use reasonable weighting to synthesize comprehensive policy indicator to reflect the comprehensiveness of each main policy indicator; undertake regression analysis for the comprehensive policy indicator, economic and stock market variable and get the effect of all kinds of comprehensive policy indictor variables on the economy and stock market; undertake regression analysis for data on the economic indicator and the data on the stock market and get the relationship between the economy and the stock market; use event research method to analyze its effect on the stock market and get some corresponding conclusions; structure the differential or difference equation groups on the interactive relationship among the variable economy, stock market and policy and do the difference operation and constitute simultaneous equation with the original main variables one after another; use quantitative regression method and solve the coefficient of the simultaneous equation to predict the operating tendency.

本研究主要内容包括：将政策变量划分为连续性政策变量和离散政策变量两个类型，并分别进行分析；对于连续性政策变量，采取合理的权重来合成政策综合指标，反映各主要政策指标的综合力度大小；将各政策综合指标与经济、股市变量进行回归分析，获得各类政策综合指标变量对经济、股市影响程度的大小；将经济指标数据与股市数据进行回归分析，获得经济与股市之间关系的大小；采取事件研究方法来分析其对股市的影响程度；构建关于经济、股市与政策各主要变量之间互动关系的微分或差分方程组，进行差分运算，并以此与原来各主要变量组成联立方程；运用计量回归方法，求出联立方程系数用于预测。

Furthermore, transfer coefficient between total content and variable speciation including acid-soluble/exchangeable, reducible, oxidisable fraction of heavy metals are different. Transfer coefficient of total Cr is 0.65 in tailings area, but that of variable speciation is 0.26. In contrast with Cr,transfer coefficient of total Ni is 0.26, but that of variable speciation is 0.67. The similar characteristics on Pb and Zn in cultivated soil, namely, transfer coefficient of total Zn is high, but low for variable speciation, which is reversed for Pb. Transfer coefficient of total content and variable speciation in abandoned soil are low compared with above two fields soil, especially, variable speciation of Cu and Ni are not transported almost down soil profile.

重金属总量和活性态（包括弱酸提取态、可还原态、可氧化态）迁移率也表现出很大差异，尾矿区土壤Cr总量迁移率较高为0.65，而其活性态迁移率较低为0.26，Ni与Cr迁移特征完全相反，总量迁移率为0.26，而活性态迁移率为0.67；农田土壤中Pb总量迁移率低而活性态迁移率高，Ni与Zn特征相似，总量迁移率高而活性态迁移率相对较低；大棚地土壤中重金属迁移率均较低，Cu和Ni活性态几乎未发生向下迁移。
