摘要
分析比较了相关分析法、多元线性回归法与逐步回归法在环境影响因子辨识中的功能异同点。以甘肃省白银市为例 ,用 3种统计学方法对城郊土壤 -作物系统重金属污染影响因子进行判别 。
Functions of the correlative analysis,multiple linear regression method and stepwise regression method in identifying environment affecting factors were compared.With Baiyin City of Gansu Province as an example for analysis,the three methods were used to identify environment affecting factors of heavy metal pollution of the soil crop system in the suburbs of the city.Based on results of the experiment,indexes were proposed for selecting plans for remedying contaminated soils in the region under research.
