| Abstract: | The purpose of this research is to develop a China-adapted AEZ methodology and applies it to assesse food productivity potential of cultivated land in China. The methodology of AEZ (Agro-Ecological Zones) is explored. Under the land utilization types and agricultural inputs of year 2000, the food productivity potential of cultivated land is assessed as follows: cereal 589.8 million ton, oil-bearing crops 30.17 million ton, and sugar crops 97.4 million ton. Results show that AEZ is an effective method for assessing land productivity potential in macro level. However, when applied to regional scale, further validation of results is needed due to inadequate accuracy of data and calibration issues. |
