摘要: 依据河南省15个夏玉米主产区1961—2015年的气象资料,计算夏玉米生育期的需水量和有效降雨量,进而得到夏玉米生育期的灌溉需水量,并利用线性倾向估计和空间插值法对河南省夏玉米生育期降雨量、有效降雨量、需水量和灌溉需水量的年际变化趋势和空间分布特征进行分析,以期为河南省夏玉米生产中水资源合理分配和灌溉方案制定提供科学依据。结果表明,在时间分布上,1961—2015年,河南省夏玉米生育期降雨量和有效降雨量年际间整体上变化趋势平稳,而需水量和灌溉需水量整体上呈明显的下降趋势。在空间分布上,河南省夏玉米生育期年均降雨量整体上由东南向西北递减,年均有效降雨量从西南向东北递减;豫西夏玉米生育期年均需水量相对高于其他区域,而豫北灌溉年均需水量明显高于其他地区。

Abstract: Based on the meteorological data from 15 stations of summer maize producing areas in Henan Province during 1961 and 2015,the water requirement and effective rainfall in the whole growth period of summer maize were calculated,thus,the irrigation water requirement was obtained.The interannual variation and spatial distribution characteristics of summer maize rainfall,effective rainfall,water requirement and irrigation water requirement were analyzed by linear propensity estimation and spatial interpolation method in Henan Province.The results showed that in terms of time distribution,the rainfall and effective rainfall in summer maize growth period had no obvious change,while the water requirement and irrigation water requirement showed significant downward trend from 1961 to 2015.In terms of spatial distribution,the average annual rainfall in summer maize growth period decreased from southeast to northwest,and the average annual effective rainfall decreased from southwest to northeast in Henan Province;the average annual water requirement of western Henan was higher than that of other regions,while the average annual irrigation water requirement of northern Henan was obviously higher than that of other regions.

Key words: Summer maize growth period;Effective rainfall;Irrigation water requirement;Spatial and temporal distribution, Henan Province
