GIS Based Analysis of Agro-climatic Divisions Scenarios in China

Global warming is one of the present research focus, and the climate change play an important role on agriculture. According to the historical meteorological data from meteorological stations, the temperature data from regional climate model prediction dataset which is provided by National Climate Center, and the agro-climatic divisions index which is suggested by State Meteorological Administration, the background characteristics and future change characteristics of agro-climatic divisions in China has been analyzed. The results show that under the condition of global warming, temperature has change slowly but shows an increasing trend, and it has increase obviously in 2100. The boundary of agro-climatic divisions has an obviously northward movement in the recent 30 years, but until 2100, most of the agro-climatic zone has north moved obviously.
