Rice is important for food security and agriculture in China.Single-cropping rice is the biggest type in plant area,distribution and output.Estimating the potential productivity of single-cropping rice scientifically has important significance to reasonable policy making for rice development and potential yield of rice.Choosing 1 km×1 km grid as the calculating unit,by using land use data,climate observation data,and agricultural statistical data,based on the agro-ecological zone model and GIS,this paper calculated the photosynthesis potential productivity,photosynthesis-temperature potential productivity,photosynthesis-temperature-water potential productivity and photosynthesis-temperature-water-land potential productivity of single-cropping rice in China.The results showed that there was obvious difference in the potential productivity of single-cropping rice in the agro-ecological zone which was basically coincident with production layout of single-cropping in China.Finally this paper put forward suggestions and solutions of single-cropping production potential productivity and national food security,which brought basic information and science hereunder for agriculture and rice development in China.
