| Abstract: |
| 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. |
