摘　　要：分析了福建省旱地土壤的水肥状况 ,认为土壤存在着退化现象 ,其主要表现是土壤水分性质不良和土壤养分亏缺 .分析数据表明 ,该区旱地土壤潜在肥力较低 ,有机质含量差异较大 ,大部分土壤氮、磷、钾养分供应不足 .土壤贮水库容小 ,尤其是土壤有效水库容有限 ,供水能力差 ,这容易导致和进一步加剧该区干湿分明的亚热带季风气候造成的夏秋季节干旱 .在此基础上 ,进一步探讨了影响土壤水肥状况的原因和因素 .In the paper,soil moisture properties and nutrient status of the dryland soils in Fujian province were analysed.The results showed that soil moisture properties were poor and soil nutrient were deficient.The analytical data revealed that the potential fertility of the dryland soils was rather low,such as nitrogen,phosphorus and potassium content in soil were deficient on the whole.The water-stroage capacity,especially the available water-stroage capacity of the sutdied Ferrisols was limited,which could promotes the progressive development of drought situation in summer and autumn in the area.Futhermore,some reasons and factors which influenced soil moisture and nutrient were discussed in the paper.
