| The protection of historic cities should be closely integrated with urban development.With the improvement of people's ideology,the protection of urban sightlines has increasingly become an important part of urban planning.However,for a long time,our control technology in historic city's sight protection plan is somewhat simple and rough,and there are also few concrete and feasible quantitative indicators,and the control measures are superficial.Through combing and analyzing the practice of sight protection control at home and abroad,based on the successful experience,this paper discusses the sight protection control plan of historic cities from the view protection system and method.On the basis of collecting a large amount of data,this paper analyzes the present situation of the protection.It reviews and summarizes the relevant urban landscape planning,and points out the deficiencies of the current method of sight protection.On this basis,it developed plans for the protection of the sight in Beijing's old city.In this paper,we use the method of GIS sight analysis to simulate human eye sight in three-dimensional space,and transform visual cognition into quantifiable control index as far as possible.The detailed and feasible control plan is put forward for the panoramic,long-range and framed scenery corridor of Beijing Old City,and quantitative analysis is made for the corridor,so as to protect and control the old city landscape,and ultimately achieve the real purpose of protecting historical and cultural city. |
