The continuous improvement of urban ecological environment puts forward higher standards on soil quality of urban green space.Besides soil nutrients and pollution，soil health quality，such as soil biodiversity and biological activity，are becoming increasingly prominent.However，there is still no recognized or unified indicator system and quantitative method for soil health quality assessment.Surface soil(0～20 cm)from urban green space in Shanghai was collected. A minimum data set for assessing soil health quality in urban green space was established by the principal component analysis and Pearson correlation analysis based on 14 soil microbial indicators.The minimum data set was composed of five indicators，including soil respiration，urease activity，xylanase activity，archaeal abundance，and microbial biomass carbon.Then，the weight of each indicator was determined(0.102～0.251).Cornell soil health assessment method was used to quantitatively evaluate soil health quality.The results showed that the average score of green space soil in Shanghai was 5.16；and 57.5% of soil samples were in“very low”or“low”level.The research results have a positive role in promoting the scientific evaluation of urban green space soil health quality and the realization of comprehensive and scientific management of urban green space soil quality.
