The physical and chemical properties of soil in different landscape of Harbin City were analyzed.Result shows that the average content of organic matter in the landscaping of Harbin City is 48.26 g kg-1 ,organic matter content in green space of trees are the highest.Soil bulk density of different green space range from 1.3 g cm- 3 to 1.48 g cm- 3 ,soil bulk density of trees is least.Total soil porosity of different greenbelts is averagely 39.82%;to-tal soil porosity of shrub land is the highest.Green space of trees has good soil structure,which can offer promotion model for soil ecological recovery in Harbin City.
