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.
