A Planning Support System for Retrieving Planning Alternatives of Historical Conservation Areas from Spatial Data Using GIS

Abstract

Urban conservation has drastically changed in theory, in practice, and even its basic definition, over the past 50 years. The definition of urban conservation is not limited to the scope of human society, which has continued to evolve since the 1931 Athens Charter. Historical towns and urban areas, as well as their natural landscapes and residential environments, are also included as subjects of urban conservation. In China, urban conservation is currently of interest to urban designers and city administrators, who are concerned with providing a historical urban identity as well as an authentic urban identity. The historical conservation areas in Beijing have become the most congested areas due to the lack of effective planning control and management, and these areas have gradually became warrens, which have been settled by numerous migrant laborers.
