几种统计学方法在环境影响因子辨识中的应用

Abstract

Abstract: 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.

Key words: affecting factor, contamination, heavy metal, identification, soil plant system, remedy, statistical method
