| 中文摘要: |
| 采用灰色关联分析法,对陕西省1983~2004年粮食年产量与粮食播种面积、农机总动力、化肥施用量、有效灌溉面积、成灾面积、农业劳动力数量等6项投入要素的关联情况进行了相关分析,以了解近22年产投结构变化情况及影响粮食产量的主要限制和推动因素。结果表明:农业劳动力数、有效灌溉面积、粮食播种面积始终是影响陕西粮食产量前三位的投入要素,化肥施用量、农机总动力、成灾面积三种投入要素对粮食产量的影响经历了由弱到强的变化。稳定耕地面积,增加有效灌溉面积,提高农村劳动力生产率,优化资源配置,是增加陕西粮食产量的主要途径。 |

| Due to the enlarging gap between grain supply and demand in Shaanxi province,it is urgent to conduct an analysis of agricultural input elements.By using the grey analysis on grain output of Shaanxi province and farming area,agricultural machinery power,fertilization dosage,effective irrigation area,disastrous area from 1983 to 2004,We will get the structure variation of input and output,the crucial factors of impacting grain output during the past 22 years.The grey analysis indicates that,from 1983 to 2004,the first three crucial factors impacting grain output of Shaanxi province are agricultural labor force population,effective irrigation area,and farming area.In terms of the impact of fertilization dosage,agricultural machinery power as well as disastrous areas affected,there experienced a change from weak to strong.In order to increase the grain output of Shaanxi province,it is suggested that more efforts should be put to stabilize farming areas,increase effective irrigation areas,promote the transfer of agricultural labor force,and optimize resource collocation. |
