摘要
本文利用主分量分析方法对模拟酸雨淋洗下,土壤淋滤液的 pH 值、Ca^(2+)Mg^(2+)、K^+、N_2^+和盐基离子总量的化学指标进行了分析,为利用土壤淋滤液评价和预测酸雨对土壤的各种影响提供了有效的手段。
This paper deals with the application of the mathematical method of principal component analysis in value of pH,Ca^(2+),Mg^(2+),K^+,Na^+ and total base cation of chemical indices of Soil solution,which is leached by simulated acid rain.Effective method was supplied by utilizing chemical indices of soil solution for evaluating and calculating different effects of acid rain on soil.
