| 摘 要： | 研究了长春地区主要类型土壤的缓冲性及土壤理化性质对土壤缓冲性的影响。结果表明：5类土壤对酸缓冲性弱程度依次为：黑钙土＞草甸土＞黑土＞白浆土＞暗棕壤；对碱的缓冲性强弱顺序是：草甸土＞白浆土＞暗棕壤＞黑土＞黑钙土；土壤碳酸钙含量、交换性盐基总量、土壤质地和有机质含量对土壤缓冲性的强弱均具有不同程度的影响。

| Abstract: | The buffer action of different types of soil in Changchun region and the influence of the physical and chemical characters of soil on the soil buffer action were studied in a simulated experiment. The results showed that the order of acid buffer capacity of the five types of soil was chernozem>meadow soil>phaiozem>planosol>dark brown earth; and the order of alkali buffer capacity of the five types of soil was meadow soil>planosol>dark brown earth>phaiozem chernozem. Effects of various degrees of the content of CaCO 3, exchangeable base capacity, soil texture and the content of organic matter on the soil buffer action were found in the experiment. |
