中文摘要在中国北方,干旱是冬小麦生育期内常见的灾害,对冬小麦的生长及产量有直接的影响。本研究以滨州灌区为例,分析了灌溉作用下干旱对冬小麦生长的影响。利用1951-2014年气象观测站的气象资料和MODIS数据,计算滨州灌区的标准化降水指数(SPI)、蒸散量、有效降水量和冬小麦的水分亏缺量及其生育期内的MODISNDVI值。结果表明,在冬小麦生育期内,该区的干旱月份占总月份的70.1%,在冬小麦生长关键的3月份、4月份、5月份、6月份,其干旱频率分别为92.2%、60.9%、39.1%、9.4%。在冬小麦生育期内,干旱月份平均水分亏缺量为697.6 mm。灌溉只能减弱干旱对冬小麦归一化植被指数(NDVI)的影响,但不能完全消除。通过分析灌溉对干旱情况下小麦的作用,可以为今后该区域冬小麦种植措施的实施提供有益借鉴。 
英文摘要Droughts are one of normal disasters during the winter wheat-growing seasons in northern China. Irrigation is one effective way to combat droughts. Analyzing the effects of irrigation under drought conditions is very important for water resource-reasonable utilization. The meteorological data and MODIS data recorded from 1951 to 2014 were used in this study to analyze this issue in Binzhou region,Shandong Province,as a case study. Standard precipitation index( SPI) ,evapotranspiration,effective precipitation( EP) ,crop water deficit and NDVI were calculated. The results indicated that the percentage of drought months to all months for winter wheat-growing season from 1951 to 2014 was 70. 1%. The drought frequency in November,March,Apirl,May and June was 92. 2%,60. 9%,39. 1% and 9. 4%,respevtively. Average annual crop water deficit during winter wheat-growing season was 697. 6 mm. Irrigation could only reduce the impact of drought on the NDVI of winter wheat,but it couldn’t completely eliminate its impact. This will help to provide more guidance and management suggestions for winter wheat growth in the region.
