中文摘要	根据国内外相关的研究成果，分析选择并确定了适宜于风沙区参考作物需水量（ET_0）的计算模式。利用典型风沙区的气象资料，对多年逐旬参考作物需水量及2001年春小麦与春玉米生育时段内逐日参考作物需水量进行了分析计算。结果表明，FAO最新修正的Penman-Moteith公式可较好地用于风沙区参考作物需水量的估算，一般ET_0值在年内与年际间变化较大，最高值发生在6月上旬左右，多年平均为5.82mm/d，最低值发生在1月上旬，多年平均0.43mm/d左右，年内各日ET_0值受气象因素的影响变幅很大，因此，精确灌溉应设法提高短期天气预报和灌溉预报的精度。
英文摘要	Weveral models of calculating reference crop evapotranspiration (ET_0) are selected and compared in calculating reference crop evapotranspiration for windy desert area in Inner Mongolia. The data collected from a weather station in the typical windy desert area was used to calculate the reference crop evapotranspiration for each ten-days period, and the daily reference crop evapotranspiration in spring wheat season and spring corn season in 2001. Results show that the latest revised Penman-Monteith equation recommended by FAO in 1998 is more suitable for estimating reference crop evapotranspiration in the windy desert area in the Inner Mongolia. Generally, ET_0 values vary obviously with time, and the variation of ET_0 of the same period also is remarkable. At average, the greatest ET_0 value is 5.82 mm/d and appears in the first ten-days of June. The least ET_0 values is 0.43 mm/d and occurs in the first ten-days of January. The daily ET_0 values are affected and determined mainly by weather factors, which indicattes the necessary of a precision weather forecast for a precision irrigation management.
