中文摘要	为了提升山西省粮食综合生产能力,促进农业可持续发展,基于山西省19782011年相关社会经济统计资料,分析了山西省近34年来粮食生产动态变化特征及各县(市)粮食生产空间差异,运用主成分分析法探讨了山西省粮食生产的影响因子。研究表明:(1)19782011年,山西省粮食呈明显波浪式增长,粮食总产量分别与粮食单产、人均粮食占有量动态变化基本吻合。(2)山西省各县(市)粮食生产呈现出明显的空间差异性,并得出自然条件较好的平原和盆地地区人均粮食占有量高,传统农业区粮食年均增长率快。(3)影响粮食生产的4个主要成分分别为:社会经济因素、农业科技水平、农业经济效益、自然灾害,并指出粮食单产、农业机械总动力、农用化肥施用量、农村用电量、财政农业支出是影响粮食产量变化的重要因子。
英文摘要	In order to improve the overall grain production capacity and promote sustainable agriculture development in Shanxi Province, based on the Shanxi Province socio-economic statistics from 1978 to 2011, and the author analyzed the grain dynamic changes and regional differences in the past 34 years in Shanxi Province, then principal component analysis was used to the impact factors of grain production in Shanxi Province. The results showed that: (1) from 1978 to 2011, the characteristics of the dynamic change about the grain production in Shanxi Province mainly performed in two aspects. On one hand, it displayed a significantly growth in grain production; on the other hand, the curve line of total grain production and the changing trends of per capita grain production and output per average of grain production were basically alike. The provinces total grain output increased from 7.069 million tons in 1978 to 11.93 million tons in 2011, output per average of grain increased from 1915 kg to 3629 kg during 1978 to 2011. (2) Grain production of various regions showed obvious space difference in Shanxi Province, per capita grain showed that Piedmont plain and basin were significantly higher than those arid mountain area, grain increase rate by degrees showed that southern grain main production area faster that the mountainous area and mining cities. (3) 4 major components of the impacts on food production were socio-economic development level, the level of agricultural science and technology, economic efficiency of agriculture, natural disasters. The contribution rate of the four main components of food production in Shanxi Province were 44.47%, 19.58%, 13.27% and 10.69%, the output per average of grain, total power of agricultural machinery, agricultural of chemical fertilizers, rural electricity consumption, fiscal spending on agriculture were the main factors in the first principal components. The correlation coefficients were as high as 0.85, 0.94, 0.97, 0.95 and 0.71.
