| Abstract: | Under the background of global warming,climate change including mean temperature,solar radia-tion and precipitation of spring Maize growth period,were studied in Northeast China using mathematical sta-tistics method based on daily data from 101 meteorological stations from 1971 to 2007.The light-temperature potential productivity and the climate potential productivity of spring maize were also analyzed using the geo-graphical information system(GIS) techniques in different areas and different times.It was s... |
