中文摘要：
酸雨是一种强电解质溶液,它与土壤接触发生液-固反应,酸雨的离子强度对土壤中电性吸附的各种离子起着至关重要的作用。本试验通过运用两种离子强度的模拟酸雨溶液,分别进行四种pH值的模拟酸雨淋滤试验,探讨离子强度与氢离子浓度对土壤缓冲力的影响。结果发现,氢离子浓度和离子强度越大,土壤的缓冲能力就越弱。
英文摘要：
Acid rain was one kind of strong electrolyte solution,which can occur liquid-solid reaction when contacts soil.The ionic strength of acid rain played a vital role on electrical adsorption of various ions in soil.Ionic strength and hydrogen ion concentration influence soil buffer force were studied,including stronger ionic strength and hydrogen ion concentration.The relationship of ionic strength and hydrogen ion concentration was studied.The result showed that the gydrogen iron concentration and ionic strength were higher,the soil buffer force was lower.
