| 摘 要： | 研究了河南郑州郑东新区新建城市绿地系统的土壤剖面、硬度等土壤特征，分析了不同绿化土壤的养分含量、结果表明，城市绿地土壤由于受人为的强烈干扰，与自然土壤相比，出现了明显的退化现象，并且随程度的增加，土壤理化性状变得更加恶化．改善城市绿地系统的土壤质量，保障绿化成果，对其进行改良是十分必要的。

| Abstract: | In this paper, we investigated the soil characters such as soil section and soil hardness and analyzed the soil nutrient contents of the new urban greening system in Zhengdong New District of Zhengzhou City, Henan Province. The results showed that compared with natural soil, urban greening soil degraded significantly due to the strong human disturbance. And with the increasing of disturbance degree, the soil physical and chemical characters became worse. To improve the quality of urban greening system and ensure the greening achievements, the urban greening soil should be meliorated. |
