Abstract

Profile samples from 0 to 70 cm depth were collected in 5 plant zones along a hydrological gradient in a typical land/inland water ecotone of the Yueliangpao Wetland, Northeast China. Total phosphorous (TP), organic phosphorous (OP), inorganic phosphorous (IP) and available phosphorous (AP) were measured to study their horizontal and vertical distribution patterns in the land/inland water ecotone, as well as their important influencing factors such as soil organic carbon (SOC) and water level. The results demonstrated that the levels of TP, OP, IP and AP were generally higher in the flooding zone (zone A), the over-wetted zone (zone B) and the drying and wetting zone (zone C), but the drying zones (zones D and E) contained lower P concentrations. It is suggested that the distributions and dynamics of P forms in soil, especially in the land/inland water ecotone, can be significantly impacted by various biogeochemical and environmental factors
