Abstract:

In order to study the impact of climate change on crop system in China, the research results of different researcher on the impact of climate change on crop system were reviewed. The results showed that the area of three crops in one year increased, the area of one crops in one year declined greatly and the area of two crops in one year changed little with the climate change in the future. The results also showed that the multi-cropping index increased all over the country, but the increase degree was different in different region. There was also some imperfectness in the researches, because the accuracy of climate model wasn’t enough and the impacts of other facts like technology development were not included in the research. In order to improve the precision of prediction, the accuracy of climate model should be improved and other factors which impacted the crop system also should be included in the study in the future.
