Research On The Landscape Design Of The Concave Terrain Space In The Mountain City

Because of the undulating and fluctuating mountain terrain,the city parks with distinctive features are formed,and the urban parks which are built on the mountain are hierarchical and stereoscopic.The mountain terrain contains five major categories,of which the concave terrain is the most abundant area of landscape change,which is beneficial to the formation of various interesting spaces.And the concave space also embodies the planned and unnatural and centripetal order,making people more inclined to be in this type of space.The plant landscape also relies on the construction of mountain terrain,which makes the plant landscape of the mountain park become a major feature of the mountain city.With the development of landscape architecture and horticulture,the role and importance of plant landscape are becoming more and more prominent,and it is scientific and practical.At present,there are many researches on plant landscape in mountainous terrain,but there are relatively few studies on plant landscape in concave terrain space,and there is no systematic research.Therefore,the design of plant landscape of concave terrain is a problem worthy of study and in-depth discussion.Therefore,from the angle of the concave terrain,this paper takes the plant landscape of the mountain park as the research object,and studies the following aspects.(1)first,from the three aspects of spatial terrain,plant landscape,plant landscape and terrain,the related research trends of plant landscape design in concave terrain space are elaborated.This paper discusses the significance of the topic,the scope of the research,the purpose of the study and the main methods,and puts forward the research framework.(2)from the environmental psychology,landscape aesthetics,landscape ecology,exterior space design four aspects to summarize the related theory of concave Terrain Landscape,defined the basic concept of concave terrain,plant landscape design;and points out the important role of plant landscape in concave terrain in space and to analyze the influencing factors of concave terrain plant landscape design.(3)the main urban area of Chongqing in the mountain city park to conduct field research,based on a sample of typical,subject diversity,regional comprehensive,terrain type diversity,size,comprehensive park construction time continuity principle,select 34 concave terrain 27 parks as the key research object this.The relationship between the concave terrain and the whole park,the vertical height difference of the concave terrain,the original and the bottom width of the concave terrain and the basic topography of the terrain are investigated.From the perspective of the relationship between concave topography,plant landscape and surrounding environment,plant design,plant space construction,plant facade level and plant and other landscape elements,five aspects are summarized.(4)Based on the results of theoretical research and field research,from the relationship with the surrounding environment,landscape layout,elevation levels,and plants and other landscape elements in four aspects,put forward the existing problems of mountain city park concave terrain landscape plants,and puts forward the design principles and strategies.The concave terrain space plant landscape design should follow the natural ecology,the overall design,focus on the characteristics and basic principles of art;and from the surrounding environment,strengthen the integration of spatial sequence,rich elevation levels,a total of four aspects of the integration of various elements of the overall design strategy;and then,U Valley,depression linear Valley,composite concave terrain put forward specific design strategies,in order to provide some reference concave terrain plant landscape design future.
