AT FIRST, URBAN PLANNIG AREA IS DIVIDED INTO DENSELY INHABITED DISTRICT, OUTER DENSELY INHABITED DISTRICT, BOTH OF WHICH ARE BELONG TO URBANIZATION PROMOTING AREA, AND URBAN CONTROL AREA FROM THE CENTER WITH CONCENTRIC RELATIONSHIP. THEN, THE CHARACTERICTICS OF URBAN PLANNING AREA ARE ANALYZED THROUGH POPULATION DENSITY OF THESE THREE TYPES OF AREA. POPULATION DENSITY DISTRIBUTION PATTERN OF URBAN PLANNING AREA IS ALSO ANALYZED. AS RESULT OF THIS STUDY, RELATIONSHIP BETWEEN POPULATION DENSITY STRUCTURE IN URBAN PLANNING AREA AND PLANNED ZONING SYSTEM IS STUDIED AND EFFECTIVENESS OF ZONING SYSTEM FOR CONTROLING URBANIZATION IS CLARIFIED AT A CERTAIN LEVEL.
