The chemical weathering index, K/Na ratio, eluvial coefficientand A-CN-K diagram , can availably indicate the evolution of pedogenic environment. The A-CN-K and CIA-K/Na diagram showed that the Holocene paleosol was in the primary stage of weathering, which K-feldspar went through weak weathering and K was less leached with much leach of Ca and Na. The intensity of weathering went stronger gradually from west to east in the Weihe Valley.
对化学风化指数、K/Na比值、残积系数等化学综合参数的研究结果显示,各项地球化学参数可有效指示成壤环境与成壤强度;从A-CN-K风化趋势图和CIA-K/Na比较图中可知,渭河流域三个剖面风化程度最高的全新世古土壤基本处于同一风化阶段,即脱Ca、Na,尚未到达脱K的阶段,还是风化较弱的初级阶段,但三者的风化程度是存在差异的,风化程度XJN剖面最低,JYC-N剖面最高,ETC剖面介于其中,说明渭河流域自西北向东南风化程度逐渐增强。
