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.
