%X The characteristics of seasonal dynamics of alkaline hydrolysis N in marsh soils of `closed' wetlands and `open' wetlands were studied.The results show that the changing tendency of alkaline hydrolysis N concentrations in surface soils shows a shape of anomalous `N' in the two(typical) sites,as for other soil layers,the contents of alkaline hydrolysis N(change gently,) but increase for each soil layer in autumn.The changing processes of alkaline hydrolysis N contents in soils from each soil layer can be fitted by three order polynomial,and these models give a good fit.
