Research On Urban Planning Strategies Of Park City In Karst Landforms

With the general acceptance of the development concepts of "ecological civilization" and "low-carbon economy",and the popularization of the contemporary value orientation of "people-centered" and "high-quality development",urban and rural development has gradually become ecological,green,people-oriented and sustainable.Continued directional transformation is inevitable.The solution of problems such as the destruction of the urban ecological environment and the loss of local characteristics in the early urbanization process urgently requires systematic and good measures,and the concept of park city that is in line with the urban ecological development space and coordinated with the urban natural and human landscape structure is proposed,which can be described as the key to solving the problem.The special topographical features of the karst landform area determine that the problems of urban and rural construction land constraints and ecological environment sensitivity are relatively concentrated.The shape and outline of the skyline imply the different potential and special path of the park city construction.How to promote the system construction and image shaping of the park city in the karst landform area through urban planning strategies,coordinate the spatial layout of Sansheng,highlight the characteristics of the city,and promote the integrated development of the city and nature,has become the focus of this paper.This paper takes cities in the karst landform area of Guizhou as the research object,takes the concept of park city construction as the starting point,sorts out the evolution of relevant urban development concepts at home and abroad and the theoretical and practical research process of park city construction,and summarizes the ecological diversity and livability of park cities,the contemporary connotation of mutual benefit,openness and sharing,and the general characteristics of ecology,integrity,uniqueness,efficiency,and openness.Secondly,the basic characteristics of the mountain city environment in the karst landform area are discussed from three aspects: the landscape pattern,the mountain-city spatial pattern,and the regional cultural environment.Then,by analyzing the "citymountain" mosaic form,landscape elements,local cultural characteristics as the adaptability characteristics of the goal of building a park city,as well as ecological sensitivity and land use constraints,the key and difficult content of the park city in the karst landform area is summarized.Finally,taking Anshun City as an example,combined with its own development foundation and spatial characteristics,the principles and goals of urban construction of landscape parks are determined.From the two spatial levels of the city area and the main urban area,it is proposed to respect the nature of the mountains and rivers and build the base of the overall ecological landscape;relying on the skeleton of mountains and rivers,guide the urban development pattern;highlight the humanistic features and create urban characteristic scenes;integrate urban and rural areas,activate the overall green corridor,as the macro and micro planning strategies,in order to provide reference for the construction of park cities in the karst landform areas of Guizhou.
