| 中文摘要: |
| 以大量的数据分析了陕西省13年以来的耕地、人口和粮食变化情况,利用平衡系数进行测算分析,同时,尝试性地提出了粮食距平系数的概念,并利用其分析了陕西十地市的粮食盈缺情况。在此基础上结合人口预测模型预测了陕西省各地市未来粮食平衡情况。 |
| 英文摘要: |
| The state of cultivated land in Shaanxi Province is complicated and various, and the contradiction of people and land, which has aggravated with the rapid economy growing since 1980's, has already been an important problem in regional sustainable development. In this article, through a large amount of data, the variation condition of cultivated land, population and grain in the past 13 years in Shaanxi Province is analyzed, and the balance coefficient is calculated. Meanwhile, the concept of grain anomaly coefficient is proposed tentatively, and it is utilized to analyze the grain situation of ten districts in Shaanxi Province. Furthermore, the population forecast model is used to predict the balance situation of grain in different districts in the future. |
