| 中文摘要: |
| 从粮食自给率、人均粮食占有量、粮食单产水平、人均耕地、粮食生产波动系数等方面构建粮食安全综合指数，采用粮食安全系数评价法，对陕西省11个地市1998～2007年的粮食安全状况进行定量评价。结果表明，在最近10年里陕西省粮食安全总体是安全的，但是各地市差异明显。由粮食安全综合评价值F的大小可以将陕西省粮食
安全大致分为3类地区：关中地区的咸阳、渭南、宝鸡属于粮食安全区；铜川、榆林、安康属于粮食临界安全区；其他地区属于粮食基本安全区。影响陕西省粮食安全的主要因素是人口持续增长、土地资源短缺、粮食生产分布不平衡、粮食生产环境恶化等。认为应该从保护
耕地、水利建设、商品粮基地建设、粮食储备以及粮食预警等方面保障陕西粮食安全。 |

| This study is to assess the status of food security in 11 cities of Shaanxi Province. An integrated index of food security, including the food self-sufficiency rate, per capita share of grain, grain production levels, per capita arable land, fluctuation coefficient in grain production etc is constructed for assessing quantitatively the status of the province's food security by taking the coefficient of food security assessment method. The results show that the food security in Shaanxi was overall safe in the last 10 years, but there are obvious differences in various parts of the province. About three types of food security have been identified, which are based on F-value of food security comprehensive assessment. Xianyang, Weinan and Baoji belong to the food security area; Tongchuan, Yulin and Ankang belong to the critical food safety area; and other regions belong to the basic food security zone. The major factors that have impact on food security in Shaanxi Province include the continuous growth of population, the few land resources, the unbalanced distribution of food production and the worsening environment for food production. A series of measures should be adopted in protecting land resources, improving water conservancy facilities, establishing production bases of grain, storing sufficient grain and establishing food warning system so as to ensure Shaanxi's food security. |
