Abstract: To evaluate the annual climate evolution characteristics in the central area of Huanghuai and adopt positive countermeasures, this paper took the meteorological data of Shangqiu from 1963 to 2010 to conduct a research on the annual evolution features of sunshine, temperature and precipitation. The results showed that: the sunshine duration tended to decrease linearly with 127.3 h/10 a, but the sunshine and temperature in different years had a different increase or decrease tendency, especially during 1991-2010, both sunshine and temperature dramatically increased or decreased, in which the average annual temperature increased by 0.49℃ compared with that of 1963-1990, 0.64℃ higher than the perennial value; while the average annual sunshine duration was 264.54 h lower than that of 1963- 1990, and 298.41 h lower than the perennial value. Precipitation growth rate was 13.1 mm/10 a, rainy season was summer and autumn, less rain season was winter and spring. The overall analysis suggests that the annual sunshine duration could meet the growth demand of two-season crops; the growth period of summer crops affected by temperature change would be prolonged, the disease and pests damage would be increased, and the growth period of wheat would be shortened and the freezing injury frequency would be decreased. The annual precipitation has a changing trend towards the south of the Huaihe River. In view of the effect of the uneven spatio-temporal distribution of precipitation and the uneven seasonal distribution of temperature, the feasible countermeasures are evaluated and analyzed.
