Abstract: The paper aims to provide data support for soil improvement and management. The author measured the soil physical properties of park and road green space in Yangpu district, Shanghai by cutting ring method, the electrical conductivity by portable soil moisture meter, and the soil hydraulic by portable osmotic apparatus. The results showed that: the soil conductivity of Yangpu district was slightly higher than the standard value of 0.05 mS/cm3, and the soil aeration was poor, the soil non-capillary porosity was 5.88% lower than the requirement of urban landscape planting; the soil bulk density of road green was 0.03 g/cm3 higher than the standard, the total soil porosity was 2.42% lower than the ideal standard of urban landscape planting, and the park green space complied with a standard; the soil water content and water holding capacity of road green space were significantly lower than those of park green space. Loosening the surface soil in time, increasing the humus content in the soil by accumulating bark and litter to reduce the soil compaction, and strengthening the daily maintenance and management to prevent the disturbance of the destruction of manmade factor, during the plant greening planting process, we can improve the soil quality from the aspect of enriching the plant community structure.
