The detection and attribution of the abrupt change of precipitation in China based on the power-law exponent;

According to the characters of abrupt change and gradual change,a twice difference based method and a window-difference maximum based method are proposed for abrupt change detection and gradual change detection separately.

According to the climate data observed by 19 weather stations in Hexi corridor from 1960 to 2005,the annual and seasonal agricultural climate resources,including light,heat and water and so on,are diagnostically analyzed by using the method of climate changing tendency,and the abrupt changes of critically agricultural resources factors are analyzed by approach of Mann-Kendall.
