摘要: 为了揭示临河地区气候变化及对春小麦产量的影响,为当地春小麦种植提供科学依据。笔者利用1975—2009年的气候资料和春小麦单产资料,分析临河地区气候变化特征及对春小麦产量的影响。结果表明:临河地区年平均温度呈波动上升趋势,其变化倾向率为0.70℃/10 a,气温突变时间点为1993年,并且大于0℃积温平均以188.4(℃·d)/10 a的速度增加;平均年降水量为150.6 mm;日照时数总体呈波动下降趋势,年日照时数的倾向率为-38.4 h/10 a;春小麦气候产量呈“M”型,1993年以前气象产量相对较低,最低的年份为1987年,1996—2000年前后气象产量相对较高,2000年以后,气象产量呈逐渐降低趋势。

Abstract: The paper aims to explore the climate change in Linhe and its impacts on spring wheat yield, and to provide a scientific basis for the scientific cultivation of spring wheat. The authors used the data of spring wheat yield and climate data from 1975 to 2009, to analyze the climate change in Linhe and the impacts on spring wheat yield. The results showed that: the average annual temperature had a fluctuant increasing trend, the change rate was 0.70℃/10 a, the abrupt change year of temperature was 1993, the accumulative temperature above 0℃ increased by 188.4(℃·d)/10 a; the average annual precipitation was 150.6 mm; the sunshine hours had a fluctuant decreasing trend, the change rate was -38.4 h/10 a; the climate yield of spring wheat presented a “M” curve, it was relatively low before 1993, the lowest year was 1987; the climate yield was relatively high in 1996-2000; after 2000, the climate yield had a gradually decreasing trend.
