Based on the site-specific observation data and related meteorological records, the influence of climate warming on potato yield and the sensitivity of potato growth to climate warming had been analyzed. The results showed that the temperature has rose significantly from 19572015 in the study region. The climate tendency rates of temperature and precipitation were 0.238 ℃/10 a,-10.517 mm/10 a, respectively. Under this situation, the potato yield was significantly negatively correlated with seeding stage(P<0.01) in June, and was significantly negatively correlated with the air temperature in tuber expansion period (P<0.01). The yield of potato decreased by about 4 391.39~6 798.46 kg·hm-2 when air temperature increased 1 ℃ from June to August. There was a negative correlation between accumulated temperature above 0 ℃ and yield. The appropriate threshold of accumulated temperature above 0 ℃ is 2 307.4 ℃. There was an positive correlation between precipitation in seeding stage and the yield of potato. The appropriate threshold of precipitation is 47.8 mm. There was a significant positive correlation between the yield of potato and sun duration in the middle of September (P<0.01). There was a significant negative correlation between the aridity index and the yield during the growing period (P<0.01). The appropriate threshold of aridity index is 1.88. During the tuber expansion period the potato was sensitive to the temperature. The yield is sensitive to temperature change from the emergence of seedling period to florescence period. The sensitive period of the potato yield to the precipitation was in the bifurcation-unfold period and unfold -tuber expansion period. And the tuber expansion period was the period which was sensitive to sun duration. Therefore, The climate warming have negative influence on potato production in the study area.
