| 摘 要： | 通过实地采集北京市6种不同城市用地土壤样品，并与北京市西山风景区土壤进行对比，分析不同绿地类型土壤的pH、可溶性盐及孔隙度特征。研究结果表明：由于受人为因素的影响，北京市建成区土壤pH均大于8．0，土壤碱化严重；城区土壤无盐渍化现象，但土壤电导率有一定的上升趋势；城区土壤孔隙度显著低于景区土壤。建议城市绿化时应选择喜碱或耐碱及适应性较强的植物。

| Abstract: | Throug with the soil in X ferent types of gr Beijing City is lar salt alkalization. h field sampling of 6 different land soil samples in Beijing City, compared ishan Scenic Area, the pH, een space soil were analyse soluble salts and porosity characteristics of dif d. The results show that the urban soil pH of ger than 8, resulted from the influence of human factors, with serious soil There is no soil salinization enomenon but a rising trend of soil electrical conductivity that the urban soil porosity is significantly lower than that of scenic area soil. City greening proposal is supposed to choose alkaliresistant plants with strong adaptability for Beijing City greening. |
