【摘要】 本研究对黔北地区土壤中活性铝的分布进行了分析,结果表明该地区目前土壤活性铝含量的平均水平较低,对于农田及森林系统尚不致有严重影响,但酸性降水对该地区黄壤中铝的溶出有潜在性危害作用。更多还原

【Abstract】 The distribution of available aluminium in soils in northern Guizhou area was investigated. The results show that the mean level of active aluminium in the soils is rather low at present time, indicating no significant effect on agricultural and forest ecosystems. However, the acid precipitation which leachs the aluminium out from the soils may be a potential danger.更多还原
