| 中文摘要: |
| 以绿地空间的详细划分为基础，通过大量实测数据的采集与分析，以南京市为例拓展城市绿地土壤酸碱度研究的广度和深度。研究结果表明，绿地土壤具有整体偏碱的特征，绿地空间形态的丰富变化在一定程度上引起了土壤pH的差异化表现。基于数据分析总结出时空连续性、地形和平面形态3个影响因素，讨论其各自成因与影响方式。作为土壤环境的重要指标，酸碱度不仅直接影响植被生长，还是各种生物、化学反应的关键调控因子。 |
| 英文摘要: |
| Based on the detailed division of green space, through the collection and analysis of a large amount of measured data, this paper selected Nanjing as an example to expand the breadth and depth of the research on the soil pH of urban green space. The research results indicated that the soil of green space had the characteristics of being generally alkaline, and the rich changes in the spatial form of the green space also caused the differential performance of soil pH to a certain extent. Based on data analysis, this paper summarized three influencing factors of temporal and spatial continuity, topography and plane form, and discussed the respective causes and influence methods. As an important indicator of the soil environment, pH not only directly affects the growth of vegetation, but also is a key regulator of various biological and chemical reactions. |
