Description :
Based on multi-source data, an effective model named the Spatial Production Allocation Model which integrates arable land distribution, administrative unit statistics of crop data, agricultural irrigation data and crop suitability data is used 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 rice production could largely be attributed to rice area decrease.
