Abstract: As an important carrier of national production and life, the park has also become an important source of carbon emissions due to its provision of huge amount of energy activities and service facilities. The park has obvious physical boundaries, independent ecosystems, clear operation and management rights, making it a natural experimental field for practicing carbon neutrality. This paper first introduces the typical composition of zero-carbon parks and the analysis of their net zero-carbon capabilities. Next, the development form of zero-carbon parks is analyzed from the four levels of physical layer, information layer, platform layer and application layer, and zero carbon operating system in the park is constructed. Then, the key technologies of zero-carbon parks are analyzed, and the existing research of zero-carbon parks is summarized in three aspects: the carbon emission accounting technology of the park, the low carbon economy system of the park, and the low carbon management technology of the park, and the shortcomings of existing research and future research directions are also analyzed. Finally, the challenges and prospects of zero-carbon park construction are proposed.
