  6. The agricultural production holds an important position in baoding area, winter wheat and summer corn are the main grain crops and cotton is the main cash crop. the water resources used in agriculture include rainwater resources used directly by crops and surface water resources or underground water resources which is used through irrigation. there have been lots of rainwater waste because of lacking in research on rainwater resources utilization and in perfect engineering technology in baoding area. to make full use of rainwater is important to alleivate the water resources crisis and improve the ecological environment, the main objectives can make more rainwater turn into soilwater that can be utilized by crops directly and decrease the crops requirments for the surface and ground water resources

    用於農業生產的水資源包括直接利用的雨水資源和通過灌溉補充的地表水資源和地下水資源。目前，保定市對直接用於農業生產的雨水資源尚未進行深入細致的研究，而且雨水資源的利用工程技術措施尚不完備，這種情況造成了雨水資源的浪費。顯然，充分利用雨水資源，即盡可能多的把天然降水轉化為可被作物利用的土壤水，減少作物對現有水資源（地表水資源和地下水資源）的需求，對于緩解保定市水資源供需矛盾，改善水環境與生態環境有重要的現實意義。
  7. 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

    根據作物需水的理論和方法，採用計算精度較高的faopenman - monteith方法（ 1998 ）計算了半乾旱區最大可能蒸散，並基於此計算五種主要旱地作物（春玉米、夏玉米、春小麥、冬小麥、棉花）和不同類型的天然草地的需水量、水分盈虧、水分訂正系數等，分析了農田和天然草地水分供需的時空分佈規律，結果表明：不同地區同一種作物的需水量是不同的，同一地區對不同作物的水分滿足程度是不同的，而且同一種作物在同一地區隨著氣候的變化需水量也會有一個年際變化；主要作物需水量由東向西，由南向北遞增，正常生長發育的水分保證程度由東向西，由南向北遞減。
