摘要：

为揭示1949年以来中国粮食生产在不同时段的发展变化特点和和总体演变趋势，从而给现阶段粮食生产发展政策的合理制定提供有力的参考，本研究运用描述性统计分析、GIS、空间分析等方法，在省域层面对中国粮食生产发展和空间分布的演变规律进行了研究。结果表明：1949年以来（1949—2009年），中国粮食总产、单产以及人均产量循着“增长—波动—增长”的轨迹向前发展，而粮食播种面积却表现出波动下降的趋势；就生产比重而言，稻谷是波动中下降的，但它在粮食作物中的比例仍然是最高的，玉米和小麦生产比重是波动上升的；粮食生产重心向东北偏移了148 km；各年代粮食产量不仅存在着显著的空间相关性，而且相近省域的空间集聚程度增加，集聚效应也越来越明显。

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.
