Abstract:

In order to reveal the development and overall trend of grain production in different times in China since 1949, and formulate reasonable development policy for the currently grain production, in this research, descriptive statistical, GIS and spatial analysis are used to analyzed the development and spatial distribution of grain production in the province level in China. The results show that: the total grain production, grain yield and the food production per capita of China follow the “growth–fluctuation- growth”, while the fluctuations in grain sown area showed a downward trend; When the proportion of the production is concerned, the rice is declining fluctuating, but it is still the highest in the proportion of food crops , the proportion of corn and wheat production is rising volatility; The study also revealed, the focus of grain production has shifted 148 km to the north-east direction in the region; The grain production is not only significant correlation between the space, grain production presented aggregated global spatial patterns at provincial level, gather effect is becoming more and more obvious.
