| 摘 要： | 农田土壤磷的淋溶损失，不仅造成肥料利用率降低、农业生产成本上升，还能引起地下和地表水体富营养化。在综合大量中外文献的基础上，阐述了农田土壤磷素淋溶问题的提出、淋溶对水体富营养化的贡献、淋溶液中磷素的形态及其比例、影响土壤磷素淋溶的因子、淋溶机理、预测方法，并对农田土壤磷素淋溶及其预测作了展望。

| Abstract: | Phosphorus (P) is an essential element for plant growth. It also is a key element for eutrophication of water bodies. The loss of P from agricultural soils not only leads to a decrease in the utilization ratio of fertilizers and an increase in the cost of agricultural production,but also gives rise to the eutrophication of surface water and ground water. Eutrophication, caused by P enrichment, first came to the fore in the 1960s, most notably in the Great Lakes region of the USA and Canada. In the following... |
