对广西靖西县新甲乡田七土壤肥力及重金属(As、Hg、Cr、Pb、Cd)污染现状进行调查与分析。结果表明,在研究区域范围内,新甲乡田七土壤中有机质和速效钾养分达到I级、II级,但区域2中速效钾是III级,但3个区域土壤速效氮均为IV级,处于缺乏状态。土壤重金属含量除Cr达到轻微污染外,其他均未超出警戒范围。从综合污染指数结果可知,3个区域土样重金属含量已达到警戒线,土壤污染水平还处于尚清洁。
The soil fertility and the status of heavy metals (As, Hg, Cr, Pb, Cd) pollution in Tianqi, Xinjiaxiang, Jingxi County, Guangxi were investigated and analyzed. The results showed that in the study area, the organic matter and available potassium in the soil of Xinjiaxiang field reached Grade I and II, but the available potassium in the area 2 was Grade III, but the available nitrogen in the three areas was Grade IV, Lack of status. Heavy metal content of soil except Cr to achieve a slight pollution, the other did not exceed the warning range. According to the result of comprehensive pollution index, the content of heavy metals in soil samples in the three areas has reached the warning level, and the level of soil pollution is still at a clean level.
