| 摘 要： | 农业是国民经济用水的大户,农业节水对水生态系统的保护与修复十分重要,在国际粮食供求趋紧的背景下.提高农业水分生产力是农业节水的关键.应用农业标准产量概念,建立农业水分生产率评价方法,以行政分区为分析单元,研究山西省农业水分生产率与灌溉强度、灌溉广度以及复种指教之间的关系,评价区域农业水分生产率状态,分析了不同区域水分生产率及单位标准产量高低的原因,为山西省水生态修复工作的开展提供基础资料. |
| 关 键 词： | 水分生产率 标准产量 复种指数 山西省 |

| Abstract: | The agricultural water is the most important part of the water used in economic systems.Agricultural water-saving is very necessary for the conservation of water ecosystem.As the gap between the demand and supply of food is becoming wide,enhancing the agricultural water production ratio is the key way for water-saving.The evaluation method for agricultural water production ratio is established based on the concept of agricultural standard yield.Through taking the regionalism as analysis unit,the relationshi... |
| Keywords: | water production ratio standard food production cropping index Shanxi Province |
