| Abstract: |
| On the basis of analyzing the changing pattern of arable land resources since the founding of People's Republic of China and changing tendency of grain yield of Shanding Province,by adopting correlation analyzing method,this paper probes into the influences exerted by arable land resources change to grain production,including the annual change rate of areas of arable land,grain sowing areas,total grain production,grain per unit area yield,and the correlation between these 4 elements;puts forward counter measures and suggestions for guaranteeing grain safety. |
| Key words: Shanding Province,grain production,arable land resources,grain sowing areas,correlation analysis |
