To provide references for the rational exploitation and utilization of climatic resources, the trend of climate change,especially the abrupt change characteristics of climatic factors in Shaanxi were investigated. Based on the observed meteorological data from 78 meteorological stations,the trend and abrupt change of climate resources,e. g. sunshine time, thermal resources and water, in Shaanxi Province from 1961 to 2014 were analyzed using linear trend analysis,Mann-Kendall abrupt test,nonparametric test and moving-1 test methods. The results indicated that:By taking Shaanxi Province as whole,the average temperature,accumulated temperature displayed significant increasing trends. The precipitation and potential evapotranspiration had no significant decreasing trends, sunshine time and wind speed had significant decreasing trends,and aridity index had no significant increasing trend. The abrupt change of temperature occurred significantly in the mid-1990s in Shaanxi as a whole, moreover, it occurred earlier in north Shaanxi than in central and south Shaanxi. The abrupt change of accumulated temperature occurred significantly in the late 1990s,and accumulated temperature occurred significantly in the 2004. There had no tested significantly abrupt change of precipitation in Shaanxi as a whole. However, the abrupt change of precipitation occurred only in the south Shaanxi in the mid-1980s. The abrupt change of sunshine time occurred in the mid-1970s, it occurred earlier in north Shaanxi and south Shaanxi than in central Shaanxi. The abrupt change of wind speed occurred in the early 1990s,it occurred earlier in north Shaanxi than in central Shaanxi and in south Shaanxi. Their abrupt change of potential evapotranspiration occurred in mid 1970s,and there is no abrupt change of aridity index. Although the change trends of temperature,light and wind resource during the period were obvious, their impact on agricultural production and ecological environment had advantages and disadvantages:Significant increase of temperature was beneficial to the growth of overwintering crops, but the risk of crop diseases and insect pests and high temperature stress is also increased. Therefore, decisions about rational exploitation and utilization of climatic resources should be made to develop advantages and avoid disadvantages.
