| 摘 要： | 研究了广州市7个功能区绿地土壤的特征,分析其在功能区的分布规律及造成差异的影响因素,并对土壤肥力进行了综合评价。结果表明:与自然土壤相比,城市土壤普遍存在压实现象,质地以砂质壤土和粉质壤土为主,pH明显升高,以中性和碱性所占比例较大,有机质和全氮含量偏低,磷含量则略高。土壤肥力以新居住区为最好,其次为公园,其后依次为老工业区,新开发区,老居住区,交通区,商业区。

| Abstract: | The soil properties of Guangzhou urban vegetation and the distribution regulations in different functional zones were studied to analyze the possible influence of human activities,and assessed the soil quality.The results indicated that the surface soil was dominated by sandy loam and light loam.Surface soil had high gravel content,high bulk density.The pH values of soil were distinctly high as compared with natural soils,and dominated by neutrality and alkali.Soil organic matter and total N were low,but total P was a little higher than natural soils.The order of soil quality coefficient in functional zones was new residence>old industry>newly developed>old residence>traffic area>inner commercial> park. |
