| 摘 要： | 农田污染是粮食高产的重要制约因素。分析了1981-2005年黄淮海地区小麦、玉米的生产现状,指出黄淮海地区这两种作物的单产、播种面积和总产在波动中持续增长;但是,由于粮食生产提高的需要,1991-2004年黄淮海地区使用了大量的化肥、农药和农膜,造成了土壤、农田灌溉水的污染,已成为粮食生产的制约因素。从实际出发,提出了农田产地环境污染的防治对策。

| Abstract: | Farmland pollution is the major restrictive factor to the grain production.The planting statue of wheat and maize in Huang-Huai Hai area were analyzed,the results showed that the planting area,the per unit area yield and the total output of wheat and maize all have a fluctuant increase in 1981-2005.At the same time,with the in- crease of grain demand,the use of fertilizer,pesticide and agricultural plastic film all increased,it has threaten the. health of farmland soil and the irrigative water in the region.The urgent missions for controlling farmland pollution are to enhance the management according to the relative laws,attach importance to the scientific research,take a series of controlling steps at the pollution source,establish the supervising systems and strength the pollution pre- caution. |
