Sustainable Regeneration Of Public Space Landscape In High Density Agglomeration Of Cities

The high-speed development of high-density and high-intensity development models in cities in China has made urban environmental problems and urban diseases prominent.The unsustainable issues such as high density,population expansion,environmental degradation,high energy consumption,and wasted resources have seriously plagued the healthy development of cities.Urban public space landscapes,as an important site for improving urban environmental quality and meeting outdoor activities of urban residents in high-density urban environments,are also threatened by unsustainable issues.In terms of reducing energy consumption,saving resources,alleviating urban greenhouse effects,coping with urban floods,reducing urban noise,and alleviating urban pollution,we must further increase the degree of emphasis.With the implementation of the concept of "sustainable development" and the development model of China's cities from incremental to quality development.Through the “sustainable regeneration” process in the public space landscape in high-density urban agglomerations,urban public space landscapes are given to relieve the oppression of high-density cities,provide more functions,reduce the consumption of energy resources,and respond to urban flooding and noise and pollution.Multifaceted capabilities.It is of great significance to the construction and development of the current urban public space landscape in China.The paper takes the high-density urban agglomeration area as the background,takes the important but scarce urban public space landscape as the research object,and supports the theory of “sustainable development” from the perspective of multi-professionals such as landscape architecture,architecture,and urban planning.To sort out and comprehensively analyze the public space landscapes and various non-sustainable issues faced by high-density urban agglomerations in various cities,and use Xi'an as an example to carry out in-depth investigation and research,aiming at various types of high-density gathering areas.The five issues of space and function,energy consumption,green planting,rainwater digestion,and pollution reduction and noise reduction have proposed the spatial superposition of functions,the reduction of energy consumption,the maximization of the benefits of water conservation and carbon conservation for garden plants,the restoration of rainwater circulation,and the adoption of The landscape approach to pollution reduction and noise reduction proposes five design principles,takes the view of creating new energy landscapes and reduces the dependence on urban power;uses urban construction waste,recycles recycled materials,and environmental protection materials to create landscapes;uses plants that maximize the benefits of water saving and carbon fixation Collocation;Form a coherent system for the digestion and utilization of rain water;Use plants to absorb waste gas and reduce noise,reducing light pollution and many other design strategies,and ultimately Through the application of the abovementioned multiple design principles and strategies in the urban public space landscape design with typical characteristics of high-density urban agglomeration areas,explore the design methods for “sustainable regeneration” of public space landscapes in high-density aggregation areas and give them high Density Concentration Area Public space landscape for better spatial perception,more versatile use features,lower energy consumption,better rainwater digestion,and a more comfortable space environment.It will help promote the improvement of the urban environment,the improvement of the environmental quality and the sustainable development of the city,and create a more sustainable urban public space.
