摘要

基于河南省1960—2015年的17个基本气象站点的气象资料,采用FAO推荐的Penman-Monteith公式和作物系数法计算了河南省葡萄需水量;并利用线性趋势分析法和Mann-Kendall非参数检验法,对葡萄生育期需水量和不同月份需水量的年际变化趋势进行了分析。同时,也对其与气象因子的相关性进行了探讨。结果表明,1960—2015年,河南省葡萄生育期平均需水量为451.71 mm。56 a来,除4月份葡萄需水量呈不显著的上升趋势外,其他月份的需水量均呈下降趋势,尤其是6月、7月和8月的需水量均呈显著下降趋势。葡萄生育期需水量的空间分布特征为自西北向东南逐渐降低,豫西葡萄生育期平均需水量最高,为460.82 mm,豫南葡萄生育期平均需水量最低,为438.15 mm。对影响河南省葡萄生育期需水量的气象因子进行相关性分析表明,日照时数和平均风速与葡萄生育期需水量有极显著正相关性,平均相对湿度与生育期需水量呈极显著负相关性。
        Basing on the meteorological data obtained from 17 basic meteorological stations in Henan province between 1960 and 2015,this essay calculated water requirement of grape in Henan province during growth period by using Penman-Monteith formula and crop coefficient method.Linear trend analysis method and Mann-Kendall nonparametric test method were also used to analyze the interannual variation tendency of water requirement in the whole growth period and different month of grape.Meanwhile,the correlation between water requirement and meteorological factors was investigated.The results showed that the average water requirement of grape was 451.71 mm from 1960 to 2015.Over the past 56 years,except that the grape water demand in April showed an insignificant upward trend,the average water demand in other months showed a downward trend,especially in June,July and August,showed a significant downward trend.The spatial distribution characteristics of water requirement during grape growth period was gradually decrease from northwest to southeast,with the highest demand in the western Henan as 460.82 mm and the lowest in the southern Henan as 438.15 mm.The analysis of meteorological factors influencing grape water requirement in Henan province indicated that the average wind velocity and sunshine duration had a remarkably positive correlation with the water requirement of grape.Whereas there was a negative correlation between average relative humidity and water requirement.
