With the increasingly severe problem of global climate change

the construction of near-zero carbon communities has become an important direction for sustainable urban development. Taking a community as an example

this paper systematically analyzes the key technical systems in the construction of near-zero carbon communities

including renewable energy construction

near-zero carbon building construction

ecological facility construction

near-zero carbon transportation system construction

near-zero carbon waste system construction

near-zero carbon control system construction

and near-zero carbon operation system construction. Through specific case studies and technical analysis

this paper reveals the application paths and implementation effects of each key technical system in the construction of near-zero carbon communities

providing references and guidance for the near-zero carbon construction of other communities.
