Exploration of Urban Ecological Recreation Space——Taking Nanjing Commercial Buildings as an Example

As urbanization accelerates and the built-up area continues to expand, people's opportunities for outdoor activities are decreasing. In addition, the pressure of survival brought on by epidemic prevention and control is forcing more and more people to choose outdoor recreational facilities to get close to nature and relax. Most people believe that low density should correspond to comfortable space, while high density corresponds to oppression and compactness. However, high-density space often brings a stronger sense of vitality, convenient living conditions, efficient and resourceful centralization, and rich living levels. I am also transforming the existing urban passive space into active space, starting with the physical and psychological needs of residents and intervening new forces into the existing urban space or architectural space to find a super-density symbiotic recreation space between people and buildings and buildings and architecture. The main content of this design is as follows: first, review the existing literature and related urban open space planning; synthesize and analyze the existing urban open space structure and typical open space functional area research results; and make an objective analysis. Secondly, to explore the recreation demand of urban commercial buildings, to explore the ideal urban recreation space structure pattern and composition elements, and to reflect on their own design. Then, we analyze the hierarchical structure of ecological open space in commercial buildings through the distribution of open space in Nanjing and propose the overall design idea of ecological open space. Finally, we summarize the shortcomings and outlook.
