The analysis on correlevity grain yield fluctuation and its relation with agricultural natural disasters in China in the recent years |
| |
| Abstract: | Taking a general view of grain yield fluctuation in China in the recent years,
the fluctuations of staple crops and their regional difference ar e discussed by
separating the fluctuation element from the whole production. Th e influence of major
natural disasters in agriculture on grain production is also analyzed. The results show
that the fluctuation of grain yield in China, to a great extent, is controlled by natural
disaster and regionality. |
