摘要: 为了研究廊坊地区夏玉米对气候变化的适宜程度,笔者对廊坊地区夏玉米各生育期和全生育期气温、降水、日照的气候适宜度进行了综合分析。结果表明:各个生育期和全生育期气温适宜度最高,其次是日照适宜度,降水适宜度最低;所有生育期气温适宜度年变化均呈弱的上升趋势,日照适宜度呈下降趋势,七叶—拔节、乳熟—成熟2个生育期的降水适宜度呈微弱上升趋势,其他生育期均呈下降趋势,且年际间波动较大。气候适宜度因受降水的影响最大,各生育期和全生育期年变化趋势和降水适宜度相同,但年际间变化小于降水适宜度。对廊坊地区而言,气温对夏玉米的生长发育是适宜的,而降水是影响夏玉米产量的主要因子。

Abstract: The paper aims to study the adaptability of summer maize to climate change in Langfang Region. The authors calculated and analyzed the climate suitability degree of temperature, precipitation and sunshine at each growth stage and the whole growth period of summer maize. The results indicated that the suitability degree of temperature was the highest, then was that of sunshine, and the suitability of precipitation was the lowest in each growth stage and the whole growth period of summer maize. The temperature suitability degree increased slightly, but the sunshine suitability degree went down in the whole growth period with year. The precipitation suitability degree decreased except in 7-leaf to jointing stage and milky to mature stage, and the inter-annual fluctuation was great. The climate suitability degree was mainly influenced by precipitation, so the tendency was consistent with the precipitation suitability degree. In Langfang Region, temperature was suitable for summer maize growth, however, rainfall was the main factor which affected the yield.
