Study On Planning And Control Of Urban Landscape Visual Corridor

Landscape visual corridor,as an important part of landscape planning and design,can ensure the visibility of urban landscape in a certain range and realize the sharing of urban resources.It is not only an important display form of visual landscape,but also to a certain extent improves the urban landscape system.Landscape visual corridor planning and control research is widely used in the protection of historic and cultural cities and green space system planning in China.It is also an indispensable part of urban design and landscape planning.It plays an important role in promoting the improvement of urban spatial form and inheritance of historical context.In the related research of urban landscape corridor planning and control in China,there are many regional levels and few macro-level cities.From the point of view of research content,it focuses on the evaluation of urban visual landscape and the control method of landscape gallery.Qualitative or semi-quantitative research is mostly used in urban visual landscape evaluation.Quantitative analysis is less and the evaluation index is unreasonable.In the study of the control methods of landscape gallery,the main focus is on the control of overlooking sight,and the expansion and evolution on this basis.In this paper,urban landscape corridor planning and control as a starting point,the scope of research to expand to the city.This paper focuses on three aspects of urban visual landscape evaluation,landscape gallery construction and landscape gallery optimization in planning control.Visual landscape evaluation research focuses on the evaluation model,which is the foundation of landscape gallery construction and optimization.The research on the construction and optimization of landscape gallery focuses on how to improve the quality of the gallery landscape.This paper tries to summarize the basic methods and relevant cases of urban visual landscape control at home and abroad on the basis of the existing theoretical results of visual landscape research.Combining the relevant technical methods such as GIS and AHP,starting with the three elements of scenic spots,field of view and corridor,it explores the construction and optimization methods of landscape corridor,with a view to providing reference for the planning and control of similar urban landscape corridors.Finally,this paper takes the project "Special Study of Landscape Gallery in Luotian County" of Wuhan University School of Urban Design as an empirical study.Based on the historical development track and current construction situation of Luotian County,this paper tries to make an empirical study on the planning control of urban landscape gallery in Luotian County through in-depth interpretation of the historical culture,landscape spatial pattern and artificial built environment of the main urban area of Luotian County,and tests the feasibility of the planning control method of urban landscape corridor.
