东南亚稻米生产时空变化格局分析

 稻米是重要的基础战略物资，其生产关乎国计民生。基于FAO数据库，从区域及国家两个层次定量分析了1961-2014年东南亚稻米生产的时空格局及其演变特征，并借助LMDI模型探讨了稻米增产的贡献因素。研究表明，1961年以来东南亚稻米生产取得了长足发展，占世界稻米生产的近30%且呈上升趋势，东南亚稻米种植向中南半岛的泰国、越南推进；东南亚国家稻米增产受单产水平提升的影响较为显著。

Spatial and temporal pattern changes of rice production in Southeast Asian

Rice is an important strategic material and its production also relates to national economy and people's livelihood.Investigation on the changes in rice production and its driving factors in traditional rice production regions is of great importance in enhancing food provision function,ensuring regional and national grain security and proclaim contributions factors.Taking the Southeast Asia (SEA) as a study area and using LMDI method and the rice production data of 1961-2014 at regional and national scales from the Food and Agriculture Organization Corporate Statistical Database (FAOSTAT),we analyze the spatial and temporal patterns and change of rice production,and we further investigate the main influencing factors of these changes.The results are as follows.Since 1961,the SEA total rice production has achieved great development,the rice production of SEA accounting for about 30% of global output and showing an overall increasing trend.Meanwhile,rice plantations of the SEA have generally expanded northward from the countries of ISEA to the counterparts in MSEA (especially Thailand and Vietnam).The main contribution factor affecting rice production was unit rice yield in the SEA.
