to get a series of spatial distributions of rice area and production and to analyze the pattern of spatial and temporal changes. Spatially , most of the increased area and production were in Northeast China, especially, in Jilin and Heilongjiang ; most
of the decreased area and production were located in Southeast China, especially, in regions of rapidly urbanization in Guangdong, Fujian and Zhejiang. This implies that rice production increase may be due to area expansion and other non-area factors, but reduced
