我国用全球8%的耕地生产了全球21%的粮食,但同时化肥消耗量占全球35%,粮食生产带来的水土流失、地下水严重超采、土壤退化、面源污染加重已成为制约农业可持续发展的突出矛盾。在“十三五”规划纲要中更是提出,重点在地下水漏斗区、重金属污染区、生态严重退化地区,探索实行 China uses 21% of the world’s cultivated land to produce 21% of the world’s total grain output. At the same time, the fertilizer consumption accounts for 35% of the world’s total. Soil and water loss caused by food production, serious over-exploitation of groundwater, soil degradation and increased non-point source pollution have become the main constraints on agriculture. Prominent contradictions of sustainable development. In the “13th Five-Year Plan” is even more proposed, with emphasis on groundwater funnel area, heavy metal pollution, serious ecological degradation areas, to explore the implementation of
