The Application Advances of Crop Models, Remote Sensing and GIS technology in Foreign Agrometeorological Service

Advanced science and technology, such as crop models, remote sensing and GIS, have played an important role in foreign agrometeorological service in recent decades. In developed countries, they are mainly applied in evaluation of crop growth condition and yield forecast, assessment and projection of impact of meteorological disasters and climate changes on agriculture and agriculture management, etc.Crop models, remote sensing and GIS applications are more mature in some countries such as the United States, France, the Netherlands, Australia and Canada. Firstly, progress of the three-techniques application in foreign agrometeorological service is reviewed in this paper. Then, Compared with the developed countries, the gaps of application of advanced science and technology inagrometeorological service in China are analyzed, including the insufficiency of research and development system and scale, lacking of thorough studies of basic theories, and needing to promote the application of these techniques.Finally, suggestions for enhancing these techniques, application in China are recommended.
