| 摘 要： | 运用误差分析方法研究了水平梯田与平作耕地冬小麦的水分供应状况的差异，讨论了水平梯田蓄水率和作物需水量的变化对水分状况的影响。认为主要是作物需水量的增大恶化了梯田水分供应状况。计算了西北黄土高原各地不同坡度水平梯田冬小麦的水分供应修正系数。

| Abstract: | The differences of water supply regimes to winter wheats between the level terraces and the plainwere studied by means of error analysis.The intiuences of the variations bofh of the water storage ratein the level terraces and of the water requirement of wheat on the water regime are discussed. It is mainly the increase of the water requirement of wheat that worsens the water supply re8ime in terracedfields, The modified coefficients of water supply to winter wheats are calculated for the level terraceswith various gradients in the northwestern Loess Plataeu. |
