Research On The Planning Of Building Height Control Surrounding The Urban Park Based On Analysis Of Sight

The urban park, as the most important greenbelt type in the city, has gradually become an important place of recreation, exercise and outdoor activities, with a resort to good ecological environment and graceful landscape resources. With the increasing acceleration of urbanization, the growing urban park use demand of the public added to the growth of building height surrounding the urban parks, which resulted in the contradiction between public demand of overlooking park landscape and internal landscape protection, was constantly activated. In the research of building height control surrounding the urban parks, correlation theory of building height control surrounding the urban parks is summarized, by means of analysis and combing researches status on building height control at home and abroad, and introducing the method of sight analysis, feasibility study of sight analysis application on building height control is theoretically analyzed, taking Hunan martyr’s park for example, height control and plan of building surrounding the urban parks is analyzed in the view of practice, the main conclusions are as follows:(1)Aiming at the phenomenon of building height surrounding the urban parks being beyond control, putting forward the importance and urgency of control the building height, according to researching on building height control at home and abroad, method of sight analysis and control and plan on building height surrounding the urban parks,proposed the limitation of general method on building control for it aiming at single landscape types, and the unban parks, as a syntheses, its surrounding building height can be guided by the application of sight analysis.(2) Based on the further study of sight analysis theory, on the principle of health, differences, objective and dynamic the method of building height control based on analysis of sight is proposed, the construction strategy of building height control mode with different landscape types is studied, and it is suggested that the selection of viewpoint and perspective, the control area and the control standard are the three most important control factors, and horizon characteristics, visual range characteristics and building shadowing relationship are the corresponding three conversion indexes of quantitative conversion.(3) Taking Hunan martyr’s park as example, in accordance with the overall thinking of target point visibility analysis, surrounding control region division and height control model construction, building height control and plan is carried out, synthesis results of plan of building height control surrounding urban parks of Hunan martyr’s park is finally gained, the result proved that the feasibility of the sight analysis method in the plan of building height control surrounding urban parks.
