Abstract:

To explore and compare the correlation between the seasonal dynamics of soil physical and chemical properties and soil enzyme activities (sucarse, urease, phosphatase) in Shanghai green land, soil samples under five types different plant communities which consist of Platanu sacerifolia, Cinnamomum camphora and Metasequoia glyptostroboides were collected and analyzed. Results showed that: First, soil physical and chemical indicators and soil enzyme activities were much higher in broad-leaf forests and mixed forests than those in coniferous and single-dominant forests, respectively. In addition, soil physical and chemical indicators and soil enzyme activities were relative higher in both autumn and winter, and expect urease and phosphatase activities were higher in spring.  Moreover, there were significant interactive effect of plant communities and seasons on soil enzyme activities, but not on soil physical and chemical indicators. On the whole, there were various degrees of correlations between different soil enzymes as well as between soil enzyme activities and soil physical and chemical properties. These results indicated that mixed forests should be the main plant community types in the construction of urban green land, and also the aimed management of soil nutrition status at different periods during the process of urban green land maintenance also should be taken much into account in
the future.
