Abstract: Frequent wetting and drying processes increase the dynamic regulation functions of soil water in the Poyang Lake wetlands. In this study, the soil textures and associated soil-water characteristic parameters were investigated using field sampling and laboratory testing in a typical wetland section at Wucheng, northern Poyang Lake. The main objectives of this paper are to analyze the spatial heterogeneity of the soil textures and water characteristic parameters in the wetland. Field investigations show that the wetland section has three different soil textures, including sand, silt sand and loam. The sand and silt sand primarily distribute at the high elevation of the wetland section, and the loam distributes at the low elevation area adjacent to the open lake water. This spatial pattern is likely to attribute to the highly dynamic water level variations due to the combined effects of local catchment rivers and the Yangtze River. The soil textures exhibit obviously spatial heterogeneity in this typical wetland section in both the horizontal and vertical directions. In addition, the van Genuchten model has the ability to capture the relationship between the soil water content and soil pressure head, and the correlation coefficient can reach up to 0.99. The saturated water content θs for different soil textures varies from 42% to 57%, and the residual water content θr varies between around 9% and 19%. The fitting values of α and n in van Genuchten model are around 0.01 cm-1 and 3.2, respectively. These results demonstrate that soil textures play an important role in soil water storage and water transport processes. Sensitivity results further indicate that the variations of soil water content are more sensitive to the values of α and n than to those of the θr and θs. The outcomes of this study will not only provide background information relating to the soil water for the future model development of Poyang Lake wetland, but also make better understanding the ecological environment changes of the lake and its wetland and how these evolve along with the water regime changes. Our study produces a first step to bridge a major gap of soil investigation in the wetland, making it possible to better understand the soil physics, chemistry and nutrient transport within the lake wetland.

Key words: soil texture, van Genuchten model, water retention curve, spatial heterogeneity, Poyang Lake wetland
