| description | Study region: Dry land in Harbin City, Heilongjiang Province, Northeast China Study focus: Water scarcity, non-point source pollution, and climate change are key challenges to the sustainable use of agricultural water and fertilizers in cold regions. These regions' unique climatic conditions, including freeze-thaw cycles, increase the complexity of managing resources. Current research is insufficient in addressing the feedback mechanisms between crop yield, pollution, and resource use efficiency in response to water cycles during growth and freeze-thaw periods. This study combines field experiments, process simulation, and optimization modeling to develop a sustainable method for regulating water and fertilizers in cold farmland. New hydrologic insights for the region: The results show that optimization increases net economic benefits per cubic meter of water by 18.69 % and reduces pollutant emissions by 20.22 %. Utilizing snowmelt and return water could save 43.8–50 % of irrigation water. Additionally, the impacts of future climate change, including altered crop water demand and precipitation patterns, could lead to a savings in irrigation water. This research provides valuable insights into the physical processes that govern the interactions between water, soil, fertilizers, crop yield, pollution, and resource efficiency, contributing to more effective water and fertilizer management in cold regions. |
