| Abstract: | In order to determine the soil fertility status of park, campus, nursery and road green space in the central district of Harbin, the pH value, organic matter, available nitrogen, phosphorus and potassium were measured at 31 sampling points in Harbin urban greenbelt. The results showed that the soil of road and campus green space was mostly alkaline, and the soil of nursery and park green space belonged to neutral or acidic soil. The average contents of organic matter, available nitrogen, phosphorus and potassium in the green space of campus and nursery were relatively plentiful, whlie the contents in the street green space were relatively poor. |
