This study is a case study of system improvement measures for urban regeneration of the historical and cultural environment. The example areas are Hwangnam and Inwang Hanok districts in Gyeongju City, which operate various systems to solve the urban decline problem caused by the historical and cultural environment regulations. The subjects of this study are resident support programs and district unit planning systems under the advanced promotion system established in the case area. As research methods, literature studies, field surveys, and in-depth interviews were conducted. Through this, the background and purpose of introduction of each system, major plan contents, and problems of the system application process were analyzed. This study drew the following implications through case studies. First, in order to more effectively promote the urban regeneration of the historical and cultural environment, it is necessary to improve the related systems in an integrated and systematic manner. Second, in order to resolve the policy distrust of local residents in the historical, cultural and environmental management system, a wider variety of planned alternatives to narrow the difference in interests between the public and private sectors should be presented.

If cultural Heritageis located in the downtown, conservation areas was developed or is being developed In most cases Therefore, in this case, the relative height of the building during construction than the regulatory limit is reasonable, is emerging need to be objectified. This study was utilizes GIS analysis techniques for 'View Corridor' and building height standards were determined. First, 'View Corridor' set and building height restrictions for the analysis of urban environmental factors were analyzed in. In particular, the topography and urban planning, and existing buildings, including the distribution of the physical urban environment, with detailed analysis on the major historical and cultural assets with a combination of a review of the impact factor for the formation of the urban landscape recognize the scope has been expanded. Second, the key selection criteria for View point largely focused on cultural Heritageand the surrounding communicative point of view and, consequently, connectivity, and symbolism, accessibility, analysis, factors such as Prospect, setting the standards by applying a detailed assessment of each item the main view point were derived. Third, the derived key View point on the terrain and landscape characteristics simulation analysis carried out by considering together the main axis, and this suggests a reasonable height for the proposed standards.
