ONE OF THE MOST SERIOUS PROBLEMS IN PRESERVATION AND REDEVELOPMENT OF HISTORIC DISTRICTS IS CONSENSUS BUILDING. BASED ON A CASE SURVEY, WE ANALYSED THE PROCESS OF COMMUNITY DESIGN BY MEANS OF SYSTEMS ANALYSIS. THE RESULTS ARE AS FOLLOWS: 1)THE LACK OF PROMOTING PARTY INSIDE THE DISTRICT OBSTRUCTED CONSENSUS BUILDING. 2)THE PROCESS IS DEVIDED INTO FOUR PERIODS. 3)THE MAIN POINTS IN DISPUTE ARE THE CONFLICT OF VALUES AND THE EMOTIONAL CONFLICT. 4)THE LACK OF ORGANIZATION FOR NEGOCIATION AMONG VALUES, SUCH AS PROTECTION OF CULTURAL PROPERTIES, COMMERCIAL ACTIVATION, AND IMPROVEMENT OF AMENITY ALSO OBSTRUCTED CONSENSUS BUILDING.
