| Abstract: | On the basis of a previous research on potential agricultural productivity, the potential land productivity of China was studied with geographic information system (GIS) and national agricultural databases which include spatial databases and attribute databases The method of GIS based study on the potential land productivity was discussed A computing method and model were put forward after stressed research on soil effective coefficient By using the mechanism methodology and relative computing models , China's national potential land productivity was computed according to the factors such as radiation, temperature, precipitation, and soil in county unit The characteristics of numeric value disperse and spatial distribution of potential land productivity in China were analyzed through classification statistics and classification mapping |
| Keywords: | GIS China potential land productivity soil effective coefficien| |
