Soil water content and soil characteristics were measured in Shuangtai Wetland, which is one of National Nature Reserves in China and is also one of major places of reed production for paper industry. Continuous measurements of surface water level, soil water content and ground water level were carried out, and samples of soil layers containing fine roots of reed were analyzed. A vertical 1D numerical model was adopted for the simulation of vertical groundwater movement to understand the variation of soil water content obtained from the field measurement. Model parameters were determined based on the soil sample analysis and relating existing studies. The computational result had a fairly good agreement with the observation though uncertainties are still remained.
