Exploration on Landscape Reconstruction Design of Old Residential Communities Embedded with Green Technology Based on Smoke-Free Environment: Regarding Shangdatianwan Central District in Yuzhong District of Chongqing a Case

Abstract

A smoke-free environment is crucial to the health of low-income, marginalized and vulnerable groups in the wake of COVID-19 and extreme weather.Low-income vulnerable groups mostly live in old residential areas, where the quality of living environment is poor. Ground buildings lack fire protection and smokeless facilities, and ground, rain and sewage pipes are mixed, posing serious safety and health risks.However, urban reconstruction and restoration often pay attention to the smoke-free environment, underground pipe network facilities and green and intelligent application of new residential areas, while ignoring the implantation of smoke-free environment, environmental protection and energy saving sustainable technology measures in the reconstruction of old residential areas.The old residential areas are the last link in the implementation of smoke-free policy and the most vulnerable areas of urban governance.Urban renewal design implanting smoke-free environment and green technology into urban fabric can improve its resilience and quality of living environment.Based on this, taking Shangdayanwan Central District, Yuzhong District of Chongqing, a typical mountain city, as an example, the reconstruction and design of the old residential area with green technology embedded in smoke-free environment was carried out, and the technical mechanism was explored, providing reference for urban renewal design to reduce pollution, prevent disasters and improve the ecological conservation of human settlements.
