| 摘 要： | 农业面源污染已成为我国环境污染的主要来源之一,随着农田氮肥施用量的不断增加,由氮素造成的农田面源污染已成为水体污染的主要原因之一。笔者综合近年来国内外专家学者的主要研究成果,分析造成农田施肥后的氨挥发、地表径流、淋溶和硝化-反硝化等氮损失4个主要途径,探讨了影响氮损失量及强度的因素,生态防护林对农田氮素在地表径流、淋溶的过程中的作用,以及影响防护林生态效能的因素。综合认为,防护林能在一定程度上控制农业面源氮素造成的水体污染,提高氮素利用率,并在此基础上就生态防护林减轻农田施肥氮损失的研究领域提出建议。

| Abstract: | The agricultural non-point source pollution has already become one of main environmental pollution problems.Non-point source pollution caused by nitrogen from cropland with increasing use of nitrogenous fertilizer became the major factor seriously causing water quality degradation seriously.In this paper,authors have collected recent published research data on nitrogen loss in farming land cited in Chinese academic journal web and some foreign references.The results indicated that there exist four main ways... |
