摘　　要：选择中国东部中温带、暖温带、亚热带、热带的16个沼泽作为研究对象,研究其土壤的有机质含量、氮含量、磷含量和钾含量的分布特征,并对其在4个气候带间和每个气候带内的沼泽土壤的理化数据变化进行了分析。结果表明:有机质含量、全氮含量、全磷含量和全钾含量在不同气候带之间的分布是有明显差异的,在同一地区内即温度大致相同的情况下其含量在不同地点不相同。从而说明气温变化不是决定沼泽土壤特征变化的主要因素。最终可表明沼泽土壤中有机质含量、全氮含量、全磷含量和全钾含量并没有随着气候带的变化而呈现出地带性分布规律。Select the eastern China in temperate and tropical,subtropical,warm temperate zone of 16 swamps as the research object,the soil organic matter content,nitrogen,phosphorus content and potassium content distribution,and in its four climate and each climate within the swamps of soil physical and chemical properties are analyzed;Results show that the content of organic matter content,nitrogen,phosphorus content and potassium content in different climatic distribution is obvious difference in the same area,the temperature is roughly the same situation its content in different locations are not the same.Thus explains temperature is not decided to change the soil characteristics of soil swamp the main factor.Finally can show soil organic matter content in the swamp,nitrogen,phosphorus content and potassium content is not as climate change and presents a wide distribution rule.
