Abstract:

According to the shihezi area 3 meteorological offices and stations in 1961-2008 meteorological data, Establish shihezi area annual average temperature, average minimum temperature, temperature, shanxi and sunlight time sequence, using linear regression, atmospheric, inspection, wavelet analysis of correlation analysis method, shihezi area nearly 48 years basic meteorological elements of change. The results showed that: (1) nearly 48 years shihezi area annual average temperature, average minimum temperature except slight fluctuations between the interannual, presents ascendant trend, the former to the latter, changes in temperature than poorer showed a trend of decrease, (2) of years shows significantly increase the temperature, the rising trend for 93.1 ° c / 10 years, the correlation coefficient of 0.546, through the confidence of alpha = 0.01 significant level, and the annual average temperature cycles of time for 16 years, 8 years plus or minus oscillation, (3) frost-free period and sunlight time all is not significant, but the increasing trend, (4) shihezi area in sunshine duration, etc, the temperature increasing of quantity of heat to the local cotton yield and quality improvement.
