Clustering analysis for speciation of Cu in soil samples of Dawu River in Dexing dopper mine
德兴铜矿大坞河流域土壤Cu元素形态的聚类分析

A sequential extraction procedure is used to analyze the speciation of Cu of soil samples in a low-grade ore plot of the Dexing Copper Mine to study how heavy metals pollute the environment.Synthesizing the characteristics of Dexing Copper Mine to make clustering analysis deeply for speciation of Cu,draw a conclusion that shift and transformation of Cu in the local soil is steady relatively and exists mainly in organic matter and the residual fraction.But the carbonate fraction and others of Cu which contribute a lot in the total speciation could transfer under the condition of acidity or oxidation.Then Cu element would pollute the environment potentially.This article contributes much value to study transform of other heavy metal and the environment treatment and reclamation of diggings in science industry.
