Construction and Application of Height Control Model of Urban Building based on GIS: Taking Guanyun County as an Example

It has become an urgent demand of urban residents to shape the appropriate urban space style and strengthen the sharing of landscape resources through the height control of urban buildings. Starting from the visual corridor of urban landscape, taking Guanyun County, Jiangsu Province as an example, a scientific and efficient height control model and planning technical framework for urban buildings were constructed based on GIS. Based on the demonstration of the surrounding area of Dayi Mountain in Guanyun County, scientific viewpoint selection and multi-dimensional line-of-sight control analysis were carried out to construct the three-level urban building height control model: reference model of urban height control, modified model of urban height control, status quo correction model of urban height control. Finally, the height control zones of urban buildings were divided and planning guidelines were proposed. It can provide reference for the research on height control of urban buildings and related planning and construction.
