Abstract
I researched some agricultural types about the periphery districts of Ube and Onoda, industrial cities in Yamaguchi Prefecture. In this research I arranged the statistical area units on the basis of communities (“buraku”). But the survey of communities is difficult because of the luck of statistical data, so I used the data of taxation office. “Farm reliance rate”, which is indicated as agricultural income/gross income×100, is one of the indicator of this area divisions, for in Japan many farmers hold side income other than agricultural managements are much influenced by this side jobs. According to the farm reliance rate, I grouped communities as follows: (A) under 49%, (B) 50-60%, (C) 65-70%, (D) over 75% (p. 9 Fig. 4). Further, these four groups are subdivisioned, viz.
Rate of allowance income farmers Rate of forest income farmers
a over 50%
b 30-49% under 19%
c under 29% under 19%
d under 29% 20-49%
e over 50%
We can observe some facts among these groups. (1) Between farm reliance rate and farm unit, we can see the plus interrelation, viz. farm unit of group A is small and that of group D is large (p. Fig.). (2) Between farm unit and its standard deviation rate (V), we can see minus interrelation, viz. community which consists of small farm unit has high rate of V, and the one which consists of large farm unit has low rate of V. But group A and B are obscured these relation (p. Fig.). (3) From the view-point of agricultural management, group B and C are most intensive, and from the view-point of farmer's gross income, group A and B are most profitable. (p. Fig.)
