| The thesis focuses its research on geochemical characteristics of soil environment in someregion of Han Yuan county the new city ,Luobogang of 8.1 square kilometers.At the sametime,the auther also determines geochemical baseline by researching on the contents ofseveral kinds of heavy mentals such as Pb,Zn,Cd,Ni,Cu ect.On the basis of above,the thesismakes the environmental geochemistry analysis of heavy metal pollution to the topsoil in thesystematic region.The main researching results are as follows:1. With the use of statistically analyzing method accumulated frequency way, theenvironmental geochemical baseline of heavy metal elements in topsoil in Han YuanLuobogang region.2. Through the Geoaccumulation Index calculation of elements such as Cr,Pb,Zn,Cd, Ni,Cu,As in topsoil in Luobogang region, the Geoaccumulation Index is from -0.07to 2.55,it is shown that most elements are in contamination level of 1 to2 ,uncontaminated/slightly contaminated;some dements are in contamination level of 3 to4,moderately contaminated/strongly contaminated.According to the GeoaccumulationIndex,the contamination degree fron strong to weak in topsoil is:Pb＞Zn＞As＞Ni＞Cu＞Cr＞Cd.3. According to the study on the environmental geochemistry of topsoil,we can get theopion that the constraction to the city is practical and the systematic is same to the soilenvironmenta geochemical.According to the study on the soil environmental geochemical,we can offord theconstractive standard or scale of the following environment changing not only nature but alsoman- made,also can give out the performing thought and working focus on managing theenvironment problem produced by moring of the city, and can take out the decision-makingfoundation to the government to plan, and can give concerned information to evaluate the soilenvironment,and can offord the scientific information about controlling the ecologyenvironment and overall propelling environment and the continuous development suggestionof the city.
