%X A two-year field located monitoring was carried out to study the impacts of hydro-periods on the lakeshore meadow wetland soil total nitrogen(TN) and hydrolysable nitrogen(HN) in Napahai plateau wetland in northwestern Yunnan province.The results show that meadow soil alternate drying-wetting is the significant characteristic influenced by hydro-periods.Hydro-periods of meadow wetland control the physical environment of meadow soil,and the occurrence of TN in the upper layer(0-20 cm) was influenced more sig...
