内容記述 | Intensive wetland reclamation and concomitant water management in Sanjiang Plain exert profound effects on dissolved iron formation and transport, affecting the primary production in the neighboring marine environment. In this report, the distribution and transport of iron in three wetland soils under various land uses were studied, and the importance of irrigation in the function of paddy fields as a source to export iron to rivers was estimated. Cultivation generally increased the accumulations of crystallized iron and amorphous iron in the 0-60 cm surface soil layer. The changed distribution of soil iron under cultivation was ascribed to the hydrological condition-driven changes in formation and transport of dissolved iron, irrigation of iron-containing groundwater, soil weathering and plowing. In particular, greatly reduced percolation and groundwater irrigation in the paddy fields and no or little water percolation in the upland fields have been causing continued long-term impacts on dissolved iron formation/transport and iron distribution in the cultivated soils. Based on representative scenarios for water budget in the paddy fields and typical levels of dissolved iron in surface runoffs and groundwater, the function of the paddy fields as a source to export iron to rivers was estimated to be greatly reduced, and might even shifted to be a sink. The overall trend in export of iron out of flooded soils of Sanjiang Plain was also discussed. | |||||
