Abstract: The precipitation suitability degree and given year had no good linearity and temperature and light suitability degree had increased with year and synthesized climate suitability had improved in jointing to tasseling period. Duing the tasseling to milky mature period, the temperature suitability degree and given year had no good linearity and light suitability degree had went down and precipitation suitability degree had increased and synthesized climate suitability improved with year. The correlative relationship between unit yield and light suitability degree in emergence to jointing, jointing to tasseling, and tasseling to milky mature are notability. The correlative relationship between unit yield and temperature suitability degree in sowing to emergence tasseling to milky mature are notability. The correlative relationship between unit yield and precipitation suitability degree in jointing to tasseling and tasseling to milky mature are notability. The climate changes are favorable for maize production, because of temperature suitability degree increasing in the future.
