| 英文摘要 | In plain regions, nitrogen (N) leaching from agricultural land during wet seasons is a major source of diffuse pollution. Clarifying the impact of different land types on the migration of water and N in the soil would be of great help for alleviating N pollution. Using combined approaches of field monitoring, literature review and farmer surveys, this study analyzed water and N dynamics within the 0-100 cm soil profile during the rainy season, N surplus and risk of N leaching across four land uses in North China Plain: grain field, vegetable field, woodland, and orchard. The results showed that: (1) Dynamics of soil water storage (SWS) followed patterns of precipitation and peaked at the end of the rainy season (September), with the highest value in vegetable field (380 mm), followed by orchard (368 mm), woodland (346 mm), and grain field (324 mm). (2) Nitrate (NO3--N) migrated downward with infiltrating rainfall, causing post-season declines in surface soils (0-40 cm) and concurrent increases in subsurface layers (40-100 cm), evidencing rainfall-driven translocation. (3) Orchard and woodland (502 and 494 kg N ha(-1)) had much greater estimated N losses than grain and vegetable fields (87 and 38 kg N ha(-1)), due to significantly higher NO3--N accumulation in the former (p < 0.05). These results highlighted that intensive rainfall and long-term high fertilization in non-grain systems, particularly orchard and woodland, substantially elevated N leaching risks. Improved management strategies that limit N buildup and mitigate intensive rainfall-induced leaching are urgently needed to curb agricultural N pollution. |
