Abstract: Based on cotton yields and meteorological data of sunlight,temperature and precipitation every ten days in Shaanxi Province,the cotton yield prediction model was established.The changes of cotton yields under different scenarios,e.g.temperature increase by 0.5℃ and by 1.0℃,precipitation change by ±10%,±20% and ±30% respectively,were analyzed.The countermeasures for a sustainable development of cotton production in Shaanxi Province were put forward.

Key words: Climate change, Climate change, Cotton yield, Impact, Countermeasure
