用Mechlich法研究沿淮地区几种类型土壤的电荷数量，结果表明：不同类型土壤电荷数量、电荷性质存在明显差异。供试土壤负电荷量大于土壤正电荷量，土壤永久负电荷量大于可变负电荷量。在沿淮几种土壤中，黄棕壤、黄褐土CECv／CEC8．2≥0．4，为可变电荷土壤，潮土和砂姜黑土为恒电荷土壤。土壤性质是土壤表面电荷的主要影响因素，CECv和CEC8．2主要受土壤pH和粘粒含量的影响，AEC主要受土壤有机质的影响。

Using the method of Mechlich, the characteristics of soil surface charge in the region along Huaihe River in Anhui Province were studied. The results showed that： There had significant difference of soil surface charge in different soil types. Generally speaking, the negative charge quantity was higher than the positive charge quantity, and the permanent negative charge was higher than variable negative charge in the tested soils. In the tested soil types, Yellow brown soil and Yellow cinnamon soil were variable charge soil, and moisturesoil and Shajiang black soil were constant charge soil. The major influencing factors of soil surface charge were soil properties. Soil pH value and clay particles were major influencing factors of soil CECv and CEC8.2, and Soil organic matter content was major influencing factor of soil AEC.
