%X Based on the daily temperature, precipitation and sunshine data of the National Weather Station of Weixian County, Hebei, China from 1961 to 2014, the average temperature, accumulated temperature, precipitation and sunshine trends of the year and four seasons were analyzed. The results showed an upward trend of the average annual temperature, average annual maximum temperature and average annual minimum temperature and the minimum temperature increase is the largest. The average temperature in summer is decreasing, while the average temperature, maximum temperature and minimum temperature in spring, autumn and winter showed an upward trend. ¡Ý0<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;#176</span>C accumulated temperature increased by 193.82<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;#176</span>C for 54 years, and ¡Ý10<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;#176</span>C accumulated temperature increased 54.59<span style=\"font-family:Verdana, Helvetica, Arial;white-space:normal;background-color:#FFFFFF;\">&amp;#176</span>C for 54 years. Weixian County sunshine hours were 119.121 h/10 years to reduce the rate of adverse effects on crop growth; annual precipitation decreased by 116.4 mm for 54 years, the maximum precipitation decreased by 8.2 mm, and the number of annual precipitation decreased 18.6 d, which caused great pressure on groundwater recharge
