中文摘要	以1980- 2015年宁夏农业统计资料为数据源,运用数理统计和GIS空间分析方法,分析了宁夏农作物种植结构的时空变化特征。结果表明: 1) 36年来宁夏农作物总种植面积增长显著,但粮食作物种植面积增长不明显。其中小麦种植面积呈快速降低趋势,玉米、薯类、蔬果等作物种植面积均呈快速增长趋势。2)宁夏主要农作物在空间分布上具有明显的地域特点。水稻主要分布在引黄灌溉区且种植比例和空间分布变化不明显;随着玉米种植比例和种植范围的迅速扩张,小麦的种植比例和分布区域明显缩小;薯类作物主要分布于宁夏南部山区,随着种植结构调整,逐步扩展到中部干旱区;蔬果类作物种植比例和分布区域扩张最为迅速。 3)宁夏农作物种植结构类型逐渐从单一型向多元组合型发展,种植结构类型更加丰富,布局更加合理。
英文摘要	In this research,we analyzed the temporal and spatial variation characteristics of crop patterns in Ningxia during the past 36 years by using the means of mathematical statistics and GIS spatial analysis,and based on the data of Ningxia agricultural statistics during 1980 - 2015. The results show that: (1) The total planting area of crops in Ningxia increased significantly in the past 36 years,but the growing area of grain crops was not obvious. Specifically,the planting area of wheat was decreased rapidly,and the planting area of corn, potato,vegetable and fruit showed a rapid growth trend. (2) The main crops in Ningxia had obvious regional characteristics in spatial distribution. Rice was mainly distributed in the irrigation district and the changes of planting proportion and spatial distribution was not obvious in the past 36 years. With the rapid expansion of the proportion and scope of corn planting,the proportion of wheat planting and the distribution area were significantly reduced. The tuber crops were mainly distributed in the mountainous area of southern Ningxia,and gradually extended to the central arid zone with the adjustment of planting structure. The planting proportion and distribution area of vegetable and fruit expanded rapidly. (3) The crop patterns of Ningxia developed from a single type to multi type during 1980 - 2015. The planting structure type was more abundant and the layout was more reasonable.
