| 摘 要： | 该文研究了郑州市城市化过程中土壤肥力质量时空变化及时空分布,结果表明:20多年来,随着土地利用集约度的不断提高,土壤有机质、全氮、速效钾含量都有所提高,仅有速效磷含量有所降低。土壤的综合肥力系数在东北西南方向较低,大面积处在差的水平,其中有少数零星分布的较高肥力。东南和西北方向的肥力较高,大部分处在良与中的水平。

| Abstract: | A study on the change of suburb soil quality and distribution in space-time for the last 20 years was conducted.The results showed that soil organic matter,total nitrogen,and available-K were improved to some extent,but the content of available-P that was reduced.The coefficients of comprehensive soil fertility in the direction from southwest to northeast was relatively low,however they were relatively high in the direction from southeast to northwest. |
