Abstract

To explore the soil physical and chemical properties in regards to the vegetation community of urban forest，and to inquire the relationship between soil and the vegetation from the urban ecology angle，soil was collected from park green spaces，road green belts，residential areas，and green space affiliated to units within the external circle highway of Shanghai City. Based on the community structure，a system of 6 forest types consists of evergreen broad-leaved forest，deciduous broadleaved forest，evergreen coniferous forest，deciduous needle-leaf forest，evergreen shrub forest and deciduous shrub forest was determined. And the polts were ascertained according to the fan-shaped grid method of landscape pattern. Physicochemical properties were measured at soil depths of 0 － 10，10 － 20，and 20 － 30 cm. Results showed that average soil organic matter（SOM） above 30 cm was 15.52 g·kg－1，average total nitrogen（TN） was 3.78 g·kg－1，and average total phosphorus（TP） was 1.13 g·kg－1. SOM and TN in the surface layer were rich and gradually decreased with depth，but TP did not show a gradual downward trend. Soil density was between 1.44 － 1.60 g·cm－3. Because average SOM，TN，and TP in the top 30 cm of urban green belt soil in Shanghai were low and compaction had increased soil density，measures are needed to improve fertility levels，especially in the newly-established green belts，to enhance the nutrient content and increase the landscape effect. ［Ch，4 fig. 3 tab. 25 ref.］
