摘要:
以日照市城区绿地表层土壤为研究对象，在野外采样和室内分析的基础上，对其土壤肥力特征进行研究。结果表明：日照市城区绿地0—20 cm土层的土壤容重为1.347～1.504 g/cm3，绿地表层土壤pH为6.64～7.01，电导率为85.534～107.079 μS/cm。土壤有机质、碱解氮、速效钾含量普遍较低，有效磷含量丰富。日照市城区不同绿地类型的土壤肥力系数（P）依次为校园绿地（1.57）、市政单位绿地（1.49）、公园绿地（1.44）、广场绿地（1.43）、苗木生产区（1.42）、居住区绿地（1.40）、道路绿地（1.39），均处于土壤肥力等级三等（0.9 < p < 1.8）。不同绿地类型的土壤退化指数为0.00%～24.67%，没有退化的趋势。
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.
