| 摘 要： | 以合肥市一环内绿地土壤和近郊蜀山森林公园土壤为对象,研究了土壤表层0~10 cm的理化特性,分析了全磷与速效磷,速效磷与潜在酸度之间的关系。结果表明,市区绿地土壤的容重平均值为1.41 kg/cm3,土壤电导率显著高于近郊森林土壤;城市绿地土壤pH值多在7.51~8.50之间,与森林土壤相比,碱性化趋势明显;城市土壤具有明显的富磷和贫氮特征,其全氮含量平均值为1.44 g/kg,全磷含量平均值为792.0 mg/kg、速效磷含量为50.6 mg/kg,分别是近郊森林土壤的0.64倍、2.9倍和5.1倍;城市土壤全磷与有效磷含量呈显著的正相关(r=0.79,p=0.000);潜在酸度与有效磷含量呈显著负相关(r=0.65,p=0.000)。

| Abstract: | Soil physicochemical properties of urban greening and suburban Shushan Forest Park in Hefei were investigated.The parameters of soil properties included bulk density,electronical conductivity(EC),pH,total N,total P and available P for the surface soil layer(0~10 cm).The results showed that the soil bulk density of urban greening averaged 1.41 g/cm3,with a rather high value of EC.Most of urban soils had pH value between 7.51 and 8.50,indicating a notable tendency to alkalinity.Compared with the suburban fore... |
