| Abstract: |
| According to meteorological data and cotton yield in in Weinan, a study was carried ou to establish assessment methods of agricultural adaption to climate change based on reviewing the previous researches on climate change adaption. The results show: (1) The climate warming and drying trends benefited cotton production in Weinan from 1980—2009; Cotton yield increased by 241 kg/hm2 and 13 kg/hm2 respectively when the temperature (Apr.～Oct.) increased by 1℃ or precipitation (Sep.～Oct.) reduced by 10 mm; (2) Human adaption has improved year by year in the background of climate change, and agro climatic adaption increased in W
einan from 62.5% in the 1980s to 93.72% in the early 21st century, however the coefficient of variation reduced from 83.7% to 6.3%. The degree of adaption to climate change in agriculture showed a clear increasing trend year by year, but the volatility decreased in Weinan. (3) Technological progress on human ability to adapt to climate change significantly helps to enhance the role of humans, and we have a strong adaption to climate change in cotton production of Weinan. |
