Abstract:
At present, Shaanxi Province is in the progress of urbanization and industrialization. Therefore, it is of great significance to keep certain areas of farmland for crop yield. The authors, with the help of tendency analysis and structure analysis, study the changing tendency of crop yield and structural changes of crop planting of Shaanxi Province after the foundation of P.R.of China. The analysis indicates that the crop production is characterized by “wave-like” pattern, although there is a stability in planting area and structure. However, there is an obvious changes of the absolute areas among different crops in the time changes, and the rise of one-crop yield has contributed a lot to the total increase of crops.The results of analysis show that there is a close relationship between land utilization and crop yield.
