ABSTRACT

With the intensification of global climate change and human activities, the fluctuation of groundwater level is becoming more and more significant, which has an important impact on the transport and distribution of nitrogen and phosphorus in soil. In this paper, the effects of water table rise and fall on the vertical transport of nitrogen and phosphorus were investigated, and the joint mechanism of hydrogeological conditions, soil type, vegetation cover and human activities on the migration pattern of nitrogen and phosphorus was analysed. Through a combination of field investigation and indoor simulation experiments, this study monitored the changes of nitrogen and phosphorus concentrations in soil profiles under different water table conditions. The results showed that the rise and fall of the water table directly affected the distribution of dissolved oxygen in the soil pore water, which in turn affected the nitrification and denitrification of nitrogen, as well as the adsorption and release process of phosphorus. The research in this paper not only reveals the control mechanism of groundwater level change on nitrogen and phosphorus transport, but also provides a scientific basis for the rational use and management of land resources.
