Study On Promotion Strategies Of Mountain Cities Planning Based On Natural Landscape Perception

Under the background of the construction of ecological civilization,urban construction paid more and more attention to the protection and utilization of natural resources.Problems such as extensive urban construction and environmental pollution have emerged in Chinese rapid urbanization.The creation of urban space ignores people’s experience and feelings.Mountainous cities faced with more problems due to the shortage of construction land and the fragility of ecological environment.The landscape pattern of "mountain-water-city" gives the mountain city a unique spatial form,but the erosion and destruction of the natural environment by the urban development leads to the gradual disappearance of the individual character of the mountain city in the trend of homogenization competition,and people’s cognition of the mountain spatial form becomes more and more obscure.From the perspective of human perception,this paper builds landscape perception theory of mountainous city.Then,the pattern of natural landscape perception in a built area of a typical mountainous city is studied.Combining urban and rural planning theories and methods,this paper puts forward some urban planning strategies to enhance mountain natural landscape perception level,in order to improve the quality of mountain city space,and to reshape the mountain city image.This paper firstly conducts basic research.Through combing and analyzing the theories and practices related to landscape perception,architectural physics,urban and rural planning,and "five senses" experience design,and mountain natural landscape.Through combing and analysis of relevant research and practice,this paper emphasizes the importance,rationality and feasibility of combining the natural landscape perception with the spatial planning of mountain cities.And the research content of this paper is discussed.Then,this paper analyzes the components of the natural landscape system of mountain cities,and makes an in-depth analysis of five human perception modes,including vision,hearing,smell,touch and taste,so as to identify the perception elements of natural landscape corresponding to the five senses.Based on the survey of public preference and typical cases,this paper summarizes the ideal modes for the perception of natural landscape in mountainous cities,including seeing mountains and waters,feeling wind and rain,seeing flowers and trees,listening to birds and cicadas,identifying fragrance and taste,and the coordination of five senses.In addition,this chapter identifies the urban space carrying the landscape perception activities,and interprets the perception frequency,perception distribution and perception approach as the basic characteristics of the natural landscape perception pattern.Finally,the theoretical system of natural landscape perception in mountain cities is constructed.Through analyzing the present situation of the natural landscape perception of a typical mountain city built area – Nan’an district of Chongqing,a comprehensive evaluation of the natural landscape perception pattern is put out based on the theory and practice of natural landscape perception in mountain cities.Three problems are identified,including missing of perception elements,unbalanced distribution of perception,and limited approaches of perception.Then,the impact on the quality of natural landscape perception in Nan’an district from urban development and construction is analyzed.Finally,based on the characteristics and deficiencies of the natural landscape perception pattern of Nan’an distract,this paper puts forward some optimization strategies of urban spatial planning from the perspective of system,technology,and methods.Such as planning system integration strategy,natural landscape resources protection and utilization strategy,natural landscape perception system construction strategy and the natural landscape perception spaces building strategy,combining the natural landscape perception with the field of urban and rural planning in mountainous areas.
