Abstract:: Soil fertility characteristics of urban green spaces in Rizhao City were exmined. The results demonstrated that soil bulk density ranged from 1.347 g/cm³ to 1.504 g/cm³ in 0—20 cm layer; pH was 6.64～7.01 and EC was 85.534～107.079 μS/cm in the topsoil. Contents of soil organic matter, available nitrogen and available potassium were low, but in contrast with these indices, available phosphorus is relative rich. Soil integrated fertility index (P) varied with locations: campus green space (1.57), municipal department green space (1.49), park green space (1.44), square green space (1.43), nursery stock production (1.42), residential green space (1.40), road green space (1.39), which are all at the third class of the soil fertility grade (0.9 < p < 1.8). Soil degradation indexes ranged from 0.00% to 24.67% for all the studied green space, indicating that no potential degeneration for all the green space soil was observed.
