Climate, topography, soil and land use data which closely associated with the distribution of maize (Zea mays L.) has been collected and collated to identify the suitable areas for maize on condition of nature and using the technique of whole plastic-film Mulching on Double Ridges in China, the database of these factors have been created in the current article. The weights of these factors, cri...
