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。
The results showed that the content of soil organic matter, total nitrogen and available potassium increased with the increasing degree of intensive land use in the past 20 years, Only available phosphorus decreased. The comprehensive soil fertility coefficient is lower in the northeast and southwest, with the large area at the poor level, among which there are a few sporadic distributions of higher fertility. Fertility in the southeast and northwest is higher, most of which are at good and medium levels.
