Abstract:: The soils in city greenbelt are the basic guarantee of plant landscape construction. the soil physical and chemical characteristics, such as pH value, nitrogen, phosphorus, potassium and ratio of carbon nitrogen are studied by collecting soil of Harbin city streets and square green space, college attached green space and nursery production green space (0—20 cm). The results show that in Harbin urban green space, the soil available nitrogen content is at the second or third level, the soil available phosphorus content and available potassium contents are mainly at the first level and show the enrichment tendency. Ratio of carbon and nitrogen in greenbelt soil is generally less than 15, and soil nutrient supply is at a medium level. Most of the soil pH values are greater than 8.5, mainly being alkaline or strongly alkaline soils. Based on soil physical and chemical analysis, this paper proposes some planting countermeasures, such as using organic fertilizers, interplanting green manure plant, replacing alkaline soil, adding impermeable ditch and reducing hazards of snow-melting agent so as to promote the sustainable development of the urban plants landscape construction.
