Study On The Protection Strategy Of The Landscape Pattern Of Hilly Cities Based On Fuzzy Comprehensive Evaluation

As the skeleton and vein of natural ecological environment,hills and rivers are the material carrier of people’s survival.Since ancient times,the history of urban construction in China has emphasized the harmonious coexistence of man and nature,the coordinated development of urban constr uction and environmental protection.However,with the accelerating process of urbanization and the rapid expansion of urban scale,people ignore the importance of ecological environment while pursuing speed and efficiency,resulting in the increasingly pr ominent contradiction between human and nature,city and ecology.Under the guidance of the trend of ecological civilization construction,paying attention to the protection of the landscape pattern of hilly cities is an important means to coordinate the c ontradiction between urban development and ecological environment,a key measure to guide the transformation of urban planning to "priority of protection and control",and a necessary way to build a hilly city with regional characteristics.Based on the above background,on the basis of on-the-spot investigation,literature sorting and systematic analysis,this paper summarizes the deficiencies of the current theoretical research and practical experience of the landscape pa ttern,summarizes the characteristics of the landscape pattern of hilly cities,constructs the protection and evaluation system of the landscape pattern of hilly cities,puts forward the protection strategies of the landscape pattern of hilly cities,and t akes the protection of the landscape pattern of Zhangjiajie central urban area as the basis In order to provide reference and guidance for the planning and construction of other cities,the actual cases are studied in depth.The thesis is divided into four parts:In the first part,starting from the research background of the gradual convergence of urban spatial and regional characteristics,the trend of ecological civilization construction,and the challenges faced by the Hilly Urban landscape environment,the purpose and significance of the research,the definition of related concepts,and the research content,methods and framework are briefly introduced,which lays the basic thinking of this paper.The second part first analyzes the relevant theoretical and practical research on "hill city" and "landscape pattern" at home and abroad,and summarizes the experience and deficiency of the current theoretical system and urban practice.Secondly,it discusses the characteristics of the landscape pattern of the hilly city.Starting from the basic connotation of the landscape pattern,it analyzes the elements of the landscape pattern and their mutual influence,expounds the mechanism and law of the evolution of the landscape pattern,and summarizes the performance characteristics of the landscape pattern in the hilly city from the three aspects of space,land use and culture in combination with the regional characteristics of the hilly city The construction of protection evaluation system and the proposal of strate gy provide the starting point.The third part discusses the evaluation indexes from three aspects: natural landscape background,urban spatial layout,regional history and culture.Combined with the fuzzy comprehensive evaluation method,the protection eva luation system of hills urban landscape pattern is constructed.Secondly,based on the evaluation system from the planning strategy,implementation strategy and safeguard mechanism,the paper explores the general methods of landscape pattern protection in hilly cities,and initially constructs a set of method system suitable for landscape pattern protection in hilly cities.In the fourth part,combined with the actual projects that the author participated in,according to the current characteristics and exi sting problems of the landscape pattern of Zhangjiajie central urban area,the application of the evaluation system and the specific practice of planning strategies are explained,so as to provide solutions for the problems faced by the landscape pattern p rotection of Zhangjiajie central urban area.
