Climate change has become a global environmental issue concerned by the international community. Study on climate change has increasingly become a frontier for academics and scholars in all fields. From subjective judgment to objective measurement, CSSCI journal papers coHected from the CNKI database in 1996 - 2016 were used. With the aid of bibliometric tools, it is a new attempt to explore the development thread of domestic climate change research and recent research hot spot within the framework of the climate change subject. It found that the current problems in the field of climate change research in China are a foUows: (i) low research level and unbalanced discipline development, (ii) relatively spatially concentrated research institutions and relatively research direction, and (iii) single research perspective of the field of agricultural climate change and lack of agricultural adaptability studies.

This paper tries to answer the question that whether farmers can adjust better to climate change in the short-term than in long-term by using panel data models and long difference models respectively. We find that short term weather shocks are less detrimental to maize yield than the long-term climate changes, which can be seen as the evidences of adaptations. For adaptation options, we find farmers choose to decrease maize planting area or enlarge the irrigation inputs to cope with the increase of extreme heat days; when there are more precipitations, farmers will increase the input of fertilizer or labor.
