本論文介紹旱作灌漑「降雨有效化」之新構想，並提出利用線性複廻歸模式之分析方法。再以日本具代表性旱作灌漑地區（8個地區）之實測灌水量及降雨量時序資料，分析降雨有效化之實態。然後根據分析結果，就各地區之需水程度及降雨有效化之狀況，按農業經營型態分類，並說明其特徵。

In this research, a new way of definiting the "Effectivity of rainfall" will be proposed. In order to analyze it, a method by the linear multiple regressional analysis has been suggested. Moreover, having analyzed the daily data of rainfall and amount of irrigated water measured in the eight farm irrigation districts which represent Japan, the condition of effectivity of rainfall was explicated; furthermore, based on the result from these analysis, we patterned the condition of water demand degree and effectivity of rainfall in the from of land use of each district, and refered to its feature.
