Based On Multi-factor Analysis Of The Urban Landscape, The Visual Environment Control

At present, China is in the rapid development phase of urbanization. The unconventional development has been caused the convergence of urban form and the loss of urban characteristics, while high-intensity development and transformation of the old city also seriously damaged the environmental conditions on which the beautiful urban landscape relies. Therefore, in the upsurge of urban development, it is of great significance to strengthen protecting and controlling the visual environment of urban landscape, and create the urban landscape with local characteristics.Based on the theories and practice of the visual environmental control of urban landscape in many domestic and foreign well-known cities, with analyzing their characteristics and summarizing their experiences, the paper educes a new method in the visual environmental control of urban landscape - the comprehensive analysis of multi-factor. It expatiates on the basic concepts and content of this analysis method, and its research methods and techniques line of building height control in the urban landscape control, which puts forward a comprehensive analysis of the line of sight from the city's skyline contour lines, sight-Gallery, street space, visual environmental protection within landscape and so on, with GIS geographic information system for the software platform, adopting a multi-factor approach to control building height.The study aims to improve the scientific nature of the Regulatory plan Index System, create a pleasant urban landscape, and protect the local features of visual environment. At present the research method has achieved very good results in the course of the actual project.
