The research of Qinling's climatic condition variations is significant for the development of rice based on local conditions and the guarantee for stable rice production,because the Qinling,one of geographical boundaries and climate transition zones in China,is sensitive to climate changes. Based on daily data of 37 meteorological stations in the south of the Qinling Mountains from 1960 to 2016 and the methods of linear trend,climatic trend rate and spatial interpolation,the paper researched temporal and spatial variations of climatic conditions during the growth period of single-season rice. The results are as follows: ① The heat resources tended to increase,the water and light resources tended to decrease in the past 57 years in the south of the Qinling Mountains. Especially since 1988,the temperature has become obviously higher and the climate has become warm and wet,and the lighting conditions have been relatively improved. ②The average temperature and ≥10 ℃ accumulated temperature and the precipitation gradually reduced from south to north in the study area. The heat injure intensity ( in July and August) gradually reduced from southwest to northeast,the drying index and sunshine hours were contrary to it. The diurnal range gradually reduced and the precipitation in the spike differentiation period increased from center to east and west. The sunshine hours of the fructicative period gradually increased from west to east. ③ There were a small increment of the high value region of the average temperature and ≥10 ℃ accumulated temperature and a large increment of the low value region. The heat injure intensity was higher in the west of the study area. There were a smaller decrement of the low value region of the diurnal range and a large increment of the high value region. The spatial variation of precipitation was complicated, the rainy areas tended to be dry and the less rainy areas tended to be moist. The climatic trend rate of the dry index decreased in the east while rised in the west. The climatic trend rate of the light conditions decreased. The above results have a practical guiding value for the single-season rice cultivation in the south of the Qinling Mountains.
