广西金秀地区不同海拔梯度的土壤环境质量分析

Analysis on Soil Environmental Quality Evaluation Based on Altitude Gradient in Jinxiu Yao Autonomous County

通过对金秀瑶族自治县不同区域和海拔的土壤理化性质(有机质、PH、阳离子交换量)、无机物(Cd、Hg、As、Pb、Cr、Cu、Zn、Ni、V、Mn、Co)、有机物(六六六、滴滴涕、苯并[a]芘、氯丹、七氯)监测,依据国家的相关标准,对不同梯度海拔土壤进行环境质量分析。结果表明:金秀地区土壤质量状况良好,土壤成分含量与海拔梯度存在一定的相关关系,海拔的升高对土壤有机物与无机物的含量有一定的影响,此研究的结果对判明该区域土壤环境质量具有一定的指导意义。

Through at different altitudes in Jinxiu Yao Autonomous County of the soil physical and chemical properties（ organic matter,p H,cation exchange capacity）,inorganics（ Cd,Hg,As,Pb,Cr,Cu,Zn,Ni,V,Mn and Co）,organics（ BHC,DDT,Benzo [a] pyren,chlordane and heptachlor） monitoring,according to the relevant standard of different elevation gradient soil environmental quality analysis,the results show that the Jinxiu Yao Autonomous County soil component content into positive and negative correlation with the local altitude gradient,the rise of altitude affect the content of soil organics and inorganics. Good soil basic situation in Jinxiu Yao Autonomous County,and altitude factor is linked to a certain extent. The results have some significance for the determination of soil environmental quality of the area.
