| 摘 要： | 农田化肥投入过量导致资源浪费和环境污染问题,成为全球关注的焦点和热点.以环渤海地区为例,利用1989-2008年统计年鉴相关数据资料,分析了区域化肥投入的总量变化、区域变化和单位农作物播种面积变化的差异.通过建立农田化肥肥效指标,评价了环渤海地区及其分省(市)的化肥施用效率,研究提出了单位农作物播种面积的化肥施用适宜量,为实现合理施用化肥、提高化肥施用效率和保护农田生态环境提供了参考依据.

| Abstract: | The excessive agricultural consumption of chemical fertilizer leads to serious resource waste and environmental pollution problems,and this has become a research focus at home and abroad.Taking the area around Bohai bay as the study area,the relevant data that come from statistical yearbooks from 1989 to 2008 was collected to analyze the change pattern of total fertilizer input,regional fertilizer input,and fertilizer input per unit crop sowing area.By establishing agricultural fertilizer efficiency indexes... |
