共享社会经济路径（SSPs）的应用与展望

The Shared Socioeconomic Pathways (SSPs) are an essential part of the new generation of climate scenarios. SSPs have been developing for ten years since their first appearance and playing an increasingly significant role in the field of climate change, both for climate projections and impact analyses. Through the bibliometric analysis of 179 publications, the current application features of SSPs are summarized, as well as the development and application status in China. We find that scenario extensions at sub-national or sectoral scales are emerging; water, land use, and health are the focuses of impact analysis; inter-model coupling and multi-model comparison are increasingly used methodologies. Currently, the development and application of SSPs in China are mainly about estimating basic scenario factors and assessing climate impacts, but the ability of scenarios to capture socioeconomic heterogeneity between different provinces and urban/rural areas needs to be improved. Finally, the future research directions of SSPs are discussed in terms of collaboration with the climate modeling teams, impact and vulnerability analysis, scenario extensions, multi-model comparison, and decision support.
