Abstract: In order to study on the impact of climate change on the growth of Sanmenxia apple, the author used the apple planting base of Sanmenxia meteorological and phenological data, the climate tendency method, comparative method, to analyze the change trend of precipitation, temperature and main meteorological disasters on apple growth influence; according to the Sanmenxia apple growing environment to partition the area, combining with climate the division method, evaluation of the climate suitability score was done. The results showed that: in 40 years to apple planting area temperature showed a rising trend in general, the warming effect of apple florescence in advance, the precipitation showed a decreasing trend; the last 3 years district climate suitability differences, Zhongshan District and part of mountain apple planting area, other areas were suitable areas and sub suitable region. It was indicated that: the meteorological disaster effect on growth of apple: high temperature effect on apple quality plateau; low temperature and frost, hail to the Zhongshan apple growth of conspicuous; precipitation reduction caused by drought disaster frequency. Sanmenxia apple producing areas of climate suitability differences, meteorological disaster effects of different planting scale, future expansion was larger space.
