华南地区军用土地金属元素含量水平和分布规律

Content of Metallic Elements in Military Land in South Chin and Their Distribution Pattern

经过对我区驻海南、两广、湖南、湖北等4个土壤采样区,32个采样点,共160个土壤样品,金属元素含量水平监测调查,结果表明:华南地区军用土地10种元素金属元素含量水平大小排序为Fe>Mg>Ti>Mn>Zn>Pb>Cr>Sr>Cu>Cd;且Fe、Mg、Zn、Cr、Mn、Ti、Cd、Pb等8种金属元素土壤含量均由北向南顺地域递减;不同元素在不同地区、不同生活区、不同土质中含量水平和分布差异均较大。

A total of 160 soil samples were taken from 32 sa mpling sites in four military sampling areas in Hainan,Guangdong,Guangxi,Hunan and Hubei to determine their content of metallic elements.The results of the investigation show that the content of the ten metallic elements in military land in South China is Fe>Mg>Ti>Mn>Zn>Pb>Cr>Sr>Cu>Cd,and that the content of eight elements-Fe,Mg,Zn,Cr,Mn,Ti,Cd and Pb-steadily declines from the north to south regions.The content and distribution of the elements vary significantly in different regions and living quarters and in soils of different quality.
