Explore the theoretical basis and implementation strategy of low-carbon Urban Community Planning

Abstract

Cities carry out various human production and living activities, consume a lot of carbon energy, become the main source of greenhouse gas emissions, and have an increasing impact on the climate. Therefore, as the main battlefield of carbon emission management, cities have become the focus of low-carbon research. The concept of a “low-carbon city” appears in dealing with global climate change. In order to further study the application of low carbon cities, this research discusses how to achieve the goal of low carbon cities from low carbon communities by introducing the concept of low carbon cities and the planning views of experts and scholars on low carbon cities, and based on the theoretical research and practical experience of low carbon cities. In the course of the study, Qianhai Cooperation Zone and Bao’an Central District in Shenzhen are introduced as case studies to analyze the practical application of low-carbon city construction. Through this study, we found that the purpose of low-carbon cities is to provide physical space for resource savings, low waste emissions, high operating efficiency, green and sustainable urban activities. For the completely dispersed urban structure in some regions of China, the polycentric network structure is a favorable urban structure for these regions to achieve low carbon and efficient development. The polycentric network cities have high urban density and activity intensity, so corresponding low-carbon strategies can be effectively implemented according to different functional positioning, density and activity density. On the other hand, in order to achieve efficient and low-carbon urban development, the community should be the basic unit. Only when low carbon is realized in the community can the basic low carbon of urban life be guaranteed and the low carbon of the whole city be realized.

Exploring urban compactness impact on carbon emissions from energy consumption: A township-level case study of Hangzhou, China

“…Townships, as fundamental administrative units in Chinese cities, accommodate approximately 65 % of China's population, contribute to nearly 60 % of China's economic output [ 75 ], and account for approximately half of China's carbon emissions [ 76 ]). Furthermore, the establishment of healthcare and educational institutions, along with the development of road transportation systems and urban pipeline networks, significantly impact the overall carbon emissions across various sectors [ 77 ]. When it comes to urban planning implementation, addressing the issue of urban compactness may appear more challenging than reducing carbon emissions.…”

Multi-Agent-Based Model for the Urban Macro-Level Impact Factors of Building Energy Consumption on Different Types of Land

“…First, more small scattered urban green space is suggested to be increased. At the same time, the existing green space that cannot effectively play the role of energy conservation can also be optimized by adjusting and improving plant types, reserving and transplanting trees, shrubs, and grasslands, reasonably allocating vegetation types, and designing vegetation hierarchy so as to improve the ecological benefit level of the urban landscape system [76]. For areas north of the river that are under construction and have low urban density, in addition to the above methods, the optimization and reconstruction of a climate-oriented energy-saving pattern can also be further considered at the planning level, such as ventilation corridors, landscape pattern networks, climate protection measures, and so forth.…”
