摘　　要：为了全面分析世界木薯生产情况,为木薯生产提供参考信息,采用属性数据空间化的方法,将地理信息系统(GIS)引入世界木薯生产的时空变化分析,利用联合国粮食及农业组织(FAO)提供的木薯生产统计数据,分析了1969—2009年世界木薯生产的空间变化、时序变化及变化趋势。结果表明,世界木薯的收获面积、总产量和单位面积产量均具有明显的空间差异;在时序变化上,世界木薯生产整体上呈稳步增长的态势,木薯主要种植大洲及主产国的生产变化各具不同的特点;在空间变异趋势上,木薯单位面积产量的南北方向变化规律最为明显,赤道往北单位面积产量随纬度的增高而增加,赤道往南单位面积产量随纬度增高而下降。GIS是一种研究木薯生产时空变化的新手段,通过研究中的分析,世界木薯的发展应采取合作交流、互助支持的发展模式,融合利用全球的土地资源、气候资源和科技资源,根据全球范围内的木薯生产潜能合理开发世界木薯资源,走木薯产业的可持续发展道路。For comprehensive analysis and provide reference information of the world cassava production, the GIS （geographic information system） was used to analyze the temporal-spatial changes and change trend of the world cassava production from 1969 to 2009 based on the cassava production statistics provided by FAO （Food and Agriculture Organization）. The results showed that, the spatial distribution of and per unit area yield had a significant geographical differences. In the changing area harvested, total output of the time series, the whole world production of cassava rising steadily, cassava production changes of the main producing continents and countries had different characteristics. In the space variation trend, the rules that north and south direction altering of the per unit area yield of cassava was the most obvious; the per unit area yield of cassava increased from the equator to north with adding latitude, and it decreased from the equator to south with growing latitude. GIS was a new technology that for researching the spatial and temporal changes of the cassava. The development model of world cassava should be taken to cooperation, exchange and mutual support. The sustainable development of cassava industry might be integrated the land resources, climate resources and technological resources of the world and developed the world cassava resources within a reasonable range based on the potential production of the cassava.
