一种确定土壤重金属污染源位置的辨识方法

确定土壤重金属污染源位置的问题是国内外研究的热门问题。考虑到当前城市土壤由于人类活动导致的环境剧烈变化,驱使自然生态系统下的自然成土过程向人工生态系统下的受人为因素干扰严重的特殊成土过程转变。提出利用因子分模型和灰色关联分析模型相结合的方法,确定污染源的位置。具体建模思路为:利用因子分析模型,筛选出受人为因素影响严重的重金属污染元素,然后利用灰色关联分析模型对筛选出的元素进行综合分析,进而确定污染源位置。

Indentification Method for Soil heavy Metals Contaminants Source

Determine the location of soil heavy metal pollution has attracted wide attention.Taking into account the current urban soil environment due to human activities lead to dramatic changes in natural ecosystems driven into the soil under the natural process of the artificial ecosystem under serious interference by the special human factors into the process of changing the soil, this paper proposes the use of factor scores and gray correlation model analysis model to determine the method of combining the location of pollution sources. Specific modeling ideas are: the use of factor analysis model selected by the serious human factors elements of heavy metal pollution, and the use of gray correlation analysis model for screening out a comprehensive analysis of the elements, and to determine the location of pollution sources.
