Urban green space is a very important part of urban ecosystem, and usually called as urban "lung". Through the functions of its supporting plants and microorganisms and itself, the soil of urban green space can beautify and clean urban environment, and has great significance for urban sustainability. Soil samples with 0~20 cm and 20~40 cm depths of park green space, road greenbelt, residential area and green space affiliated to units were collected at central district in Shenzhen city, and soil texture, bulk density, porosity, CEC, pH, organic matter, N, P, K were studied in this paper. The results indicated that the soil texture was dominated by sandy loam and light loam, the soil texture for 20~40 cm depth was accounted for loose sand and tight sand to a certain degree. Gravel content was high in soil, heavily gravelly soils account for more then 91%. Surface soil (0~20 cm) had a high bulk density, low porosity, and low CEC. The pH value of urban green space soils in Shenzhen city were distinctly high as compared with natural soils, and dominated by neutrality and slightly acid. soil organic matter was low, total N, alkali-hydrolyzable N and total P, was very low, soil available P, total K and available K was medium or over medium. Organic matter, total N and alkali-hydrolyzable N in soils with 0~20 cm depth were much higher than those with 20~40 cm depth. According soil quality situation of urban green space in Shenzhen city, some measures and suggestions were put forward for soil scientific management.
