摘 要:对哈尔滨市道路交通绿地、居住区绿地、公园广场绿地和防护绿地共43个样地,采集40~60 cm层次土样,对采集土样分别测定土壤p H值、有机质、速效钾、有效磷和碱解氮的含量。结果表明:哈尔滨市绿地土壤的p H基本呈碱性,土壤有机质、有效磷和碱解氮含量偏低,而有效钾的含量相对较高。利用方式不同,城市土壤的化学性质也有着显著地差异。哈尔滨市城市绿地土壤肥力由低到高基本为道路交通绿地〈居住区绿地〈公园广场绿地〈防护绿地。因此在不同绿地类型进行城市绿化时,应注意城市绿地土壤的特点,为以后城市绿地土壤改良提供一定的理论基础。A total of 42 soil samples from the road traffic green space,residence area green space,park plaza green space and protective green space in Harbin were investigated and the 40- 60 cm soil layers of the soil samples were tested in terms of p H,organic matter,available potassium,available phosphorus and available nitrogen content. The results showed that soil p H values were a little higher indicating that the soil was saline alkaline. But the soil organic matter,available phosphorus and available nitrogen were a little lower,while the available potassium was a little higher. The order of the fertility quality of urban green soil in Harbin was road traffic green space residence area green space〈 park plaza green space 〈protective green space. Therefore,we should pay attention to the characteristics of the soil while greening different types of green space. The study has provided a theoretical basis for future soil improvement in urban greenbelts.
