摘要
为了分析巴南区气候对玉米产量的影响,采用了重庆市巴南区多年气象观测资料及玉米产量资料,运用气候诊断和统计分析方法,围绕玉米产量和气象要素的相关关系开展研究,结果表明:巴南区年平均气温缓慢下降,年降水量呈减少趋势,年日照时数缓增;巴南区历年气温、降水、日照突变均不明显。相关分析、丰歉年分析和积分回归分析方法表明,气候对巴南区玉米的产量有较大影响:巴南区气候变化总体上不利于玉米的丰产。
To study the impact of climate on the yields of Corns of Banan District, Chongqing, using muhiple methods of climatic diagnosis, this article analyzes the connection between the corn yields and the climatic factors. The results showed that the air temperature of Banan District was slowly declining and the annual precipitation also had an inclination of decrease, while the annual sunshine hours slightly increased. Extreme changes of the air temperature, precipitation and sunshine hours were not obvious. Variety of analytical methods showed that climate change of the Banan District had a great influence on the yield of corn, and on the whole, was not conducive to corn yield.
