Abstract: The study aims to provide references for crop production in winter wheat area of Kashgar. The data of temperature, precipitation, sunshine duration from 1981 to 2014 during the growth period of winter wheat in Kashgar was used to study the variation characteristics of climate factors and their effects on winter wheat growth and development by the climate statistical method. The results indicated that the annual average temperature change during winter wheat growth in Kashgar showed an increasing trend. The precipitation showed a decreasing trend in the first two months after winter (March and April), and an obviously increasing trend in the rest time. Meanwhile, the effective accumulative temperature and the sunshine duration showed an increasing trend. Each development stage of winter wheat was ahead of schedule in different degrees during recent 34 years, especially the early stage and the jointing stage, but the overwintering stage showed a trend of delay. The temperature, effective accumulative temperature and the sunshine duration were negatively correlated with each development stage of the winter wheat. In short, the main reason for the advance of winter wheat growth period was the increase of temperature, effective accumulative temperature and sunshine duration. The impact of climate warming on winter wheat growth was significant in Kashgar.
