新疆耕地和粮食生产力变化的区域差异分析

由于自然和人为因素的影响,耕地的数量、质量在时空上存在较大差异,科技进步等人文因素对各个区域的粮食单产造成不同程度的影响,这些都直接影响到新疆的16个区域的粮食生产水平的分异.从新疆各个区域1996-2004年的耕地面积、粮食产量及粮食播种面积等农业统计资料出发,分析新疆耕地面积和粮食生产力变化的区域差异,并简要分析其变化的原因,从而为新疆农业发展,尤其是粮食生产的发展提供了科学的参考依据.

Regional Differences in Cultivated Land and Grain Productivity in Xinjiang

With the development of economy and society,cultivated land area and grain production in Xinjiang Autonomous Region have greatly varied.Because of the natural and human factors,the quantity and quality of the cultivated land are different in time and space,and advance in science and technology also has a different effect on grain production in every region,which results in difference of grain productivity in sixteen areas of Xinjiang Autonomous Region.Based on the agricultural statistics of cultivated area,grain yield from 1996 to 2004,this paper analyzes the difference of the quantity change of cultivated land area and grain productivity change,providing scientific foundation for protecting cultivated land and improving agricultural production,especially grain production in Xinjiang Autonomous Region.
