• Acceding to the theory of crop water requirement , maximum potential evapotranspirations are calculated by applying fao penman - monteith method , and then we obtain the water requirement , water balance and water correction factors ect . of main crops ( spring maize , summer maize , spring wheat , winter wheat , cotton ) and different type grasslands , and the space - time distribution regularities of water requirement of cropland and natural grassland are analysed , the result show : the water requirements of same kind crop in different areas are different , water satified degrees are different to different crops in the same area , and water requirement of same crop are different between years for climatic variation ; the water requirements of main crops are increasing from east to west and from south to north , water satified degrees are decreasing from east to west and from south to north . in growing season , there are deficits in crops water supply in most area , so the irrigation is needed to meet the requirement for crop growing normally
  根据作物需水的理论和方法，采用计算精度较高的faopenman - monteith方法( 1998 )计算了半干旱区最大可能蒸散，并基于此计算五种主要旱地作物(春玉米、夏玉米、春小麦、冬小麦、棉花)和不同类型的天然草地的需水量、水分盈亏、水分订正系数等，分析了农田和天然草地水分供需的时空分布规律，结果表明：不同地区同一种作物的需水量是不同的，同一地区对不同作物的水分满足程度是不同的，而且同一种作物在同一地区随着气候的变化需水量也会有一个年际变化；主要作物需水量由东向西，由南向北递增，正常生长发育的水分保证程度由东向西，由南向北递减。
