摘　　要：通过湖北省孝感市安陆、大悟、汉川、孝昌、孝南、应城、云梦的水稻土有机质及全量氮磷钾状况进行的测定分析表明:各地有机质及全量氮磷钾间的含量差异颇大,总体表现为全钾含量较高,其他元素含量中等。全钾含量除应城外,均高于世界土壤的平均水平;全磷含量差异较大,表现为孝南较大,云梦较低;全市水稻土中有机质及全量氮磷钾含量间的相关性均未达到显著水平,仅全磷与有机质、全氮和全钾呈负相关。The analysis of the organic matter, total nitrogen, phosphorus and potassium of paddy soil in the Xiaogan city of Hubei province （Anlu, Dawu, Hanchuan, Xiaochang, Xiaonan, Yingcheng, and Yunmeng） shows： the contents of N, P, K and organic matter in different areas varies greatly. In general, total K content is very high, and others are at medium level. Except in Yingcheng, total K content is higher than the average level of the world. There is a significant difference about total P content, the highest in Xiaonan, and the lowest in Yunmeng. Oraganic matter, total N, P, and K have no clear positive correlation, the negative corrleation exists between total P and organic matter, total N and total K.
