The objective of this study is to approach on the spatial boundary of rural development protect by areal classification technique with spatial reference to searching of areal homogeneities in two hierachial administrative units, Ri Eup/Myun. In this study, a criterion for judging areal homogeneities is the degree of agriculture and urbanizing. Variables selected by these two criteria are analysed with the method of fator analysis. The results of areal analysis are as follows: first, generally, the importance of agricultural factors in areal analysis is getting less. Second, areal classification by Myun, Ri in Ansong City is revealed variously because of urban factors. Urban factors make areal heterogeneities become greater, Therefore urban factors are important when analyzing areal characteristics. Third, lately, in areas near by Chung- cheong Do and areas with bad road's condition, areal heterogeneities have been also getting greater. The results of analysis about areal characteristics of Myun and Ri are different from each other. In addition, urban factors are more influential on the areal characteristics than agricultural factors. Therefore, the establishment of rural development project for inindle spatial boundary between Myun unit and Ri unit is needed.

In the study it is assumed that regional characteristics of each Ri within a Myeon are different in certain degrees. This assumption implies that in some case of rural planning, Goon(county) or Myeon may be inadequate as a planning unit. because regional characteristics within Myeon will vary in a considerable degree. The objective of this study is to obtain knowledge relevant to ascertaining planning units by classifying entire number of Ri in Ansung Goon according to the components of regionality, namely the degree of sustaining agriculture and the degree of urbanizing. There was a significant variation among Ri within a Myeon the degree of sustaining agriculture as well as in the degree of urbanizing. In this study it is implied that rural program planning of Goon as a whole seems to be irrelevant. And planning Myeon level programs needs eventually adjustments in such a way of eliminating areas(Ri) which are of inconsistent character. Some planning such as farming cooperation may be efficient if they are to be undertaken at Ri basis. If the program planning include such activities of marketing and cooperative use of facilities, a group of Ri in consistent nature of regionality can be a unit of planning.
