摘要 本文根据1963—2010年黄淮中部地区商丘市的气象数据资料,开展了降水量演变特征的研究。结果表明,黄淮中部麦区全年降水演变特征存在较多的异同点,随着气候变暖,商丘市降水全年变化趋势为线性增加趋势,气候倾向率为13.1 mm/10年;季节分布呈现冬前、冬季和夏季降水量增多,春季和小麦出苗前后降水量减少的特点,总体分析认为,全年降水有向淮河以南转变的趋势。 In this paper,based on the meteorological data from 1963 to 2010 in Shangqiu City,central region of Huang-Huai,the study of the evolution characteristics of precipitation were carried out.The results showed that there were many similarities and differences in the evolution characteristics of the annual precipitation in the central wheat region of Huang-Huai. With the warming of climate,the annual change trend of precipitation in Shangqiu City was linear increasing trend,and the climate tendency rate was 13.1 mm per 10 years. The seasonal distribution showed an increase before winter and in winter and summer,and showed a decrease in spring and before and after wheat seed germination. The overall analysis showed that the annual precipitation had a trend of changing to the south of Huaihe River.
