Abstract
Land valuation by means of marks allocation is a method for deciding substitute lots for the purpose of grouping of farm land. But this method when applied to paddy fields gives rise to many problems. The objective of this paper is to investigate the feasibility and practicability of this method of substitute lots decision when applyed to the grouping of paddy field. As a result of this study the method for deciding substitute lots according to a definite order is proposed here as a new method for the purpose. As a first step in this study, the factors affecting the effectiveness of labor in the paddy fields are examined by presuming that the factors affecting the productivity of the land are more or less constant.
With the function formed from these factors, the condition of the paddy field of each farmer is then expressed. It is my opinion that the function Σli, namely the summation of the distance from one's farmstead to each lot, obtained from this study is the most suitable function for this.
This function is set on an order of increasing magnitude, and the substitute lots are then decided according to that order.
