However,the removal of soil noncrystalline aluminum with DCB soultioncaused an obvious decrease of soil SSA.3.The hydroxy aluminum in the interlayer of 1.4nm intergrade mineralhad an important negative effect on the cation exchange capacity ofsoil colloids.Its removal would cause a significant increase in CEC valuesof the soil colloids.4.Free aluminum was the major carrier of phosphate adsorption of soilcolloids.Particularly,the active aluminum had a decisive effect on thecapacity of phosphate adsorption of soil colliods.5.Addition to the effects of other soil constituents on soil surfaceproperties,it was thought that the effect of soil free aluminum,especially active aluminum on soil surface properties,deserved closeattention.

焦磷酸钠、草酸铵、DCB、柠檬酸钠和NaOH提取的土壤铝对提高土壤CECv、AEC、PZC和PZNC起重要作用，尤以活性铝的作用较大。2）用草酸铵处理除去铝后，土壤比表面积变化不大或略有增加；用DCB处理除去土壤铝后，土壤SSA明显降低。3）层间羟基铝对土壤胶体的阳离子交换量有显著负贡献，用柠檬酸钠将之除去后，土壤胶体的阳离子交换量明显增加。4）土壤胶体中的游离铝是土壤胶体吸附磷的主要载体，尤其是其中的活性铝，对土壤胶体的磷吸附能力起决定性作用。5）除其它土壤组分对土壤表面性质的影响外，土壤中的游离铝、尤其是活性铝对土壤有关表面性质的影响，值得引起特别的重视。
