河南省不同区域气象因子对玉米产量的影响

为了探究气象因子对河南省玉米产量的影响，以河南省为研究区域，根据2008-2017年河南省气象资料和玉米产量资料，研究了河南省五大区域（豫南、豫北、豫东、豫西和豫中）温度和降水的变化特征，分析了河南省五大区域玉米产量的变化，阐明了温度，降水对玉米产量的影响。结果表明，2008年-2017年河南省年均气温有逐年增加的趋势，河南省五大地区降雨年际间波动较大，豫东地区和豫北地区玉米产量高于其他地区，气温和降水量与玉米产量均呈正相关。

Effects of Meteorological Factors on Maize Yield in Different Regions of Henan Province
Abstract：In order to explore the influence of meteorological factors on maize yield in Henan Province, the variation characteristics of temperature and precipitation in five regions of Henan Province were studied according to the meteorological data and maize yield data of Henan Province from 2008 to 2017. The effects of temperature and precipitation on maize yield were analyzed. The results show that the average annual temperature of Henan Province increases year by year from 2008 to 2017, the rainfall fluctuates greatly between the five regions of Henan Province, and the maize yield in eastern Henan and northern Henan is higher than that in other regions. Temperature and precipitation are positively correlated with maize yield.
