A dynamic dataset of plant community composition in Xingkai kettle peatlands (2012-2018)

The formation of kettle peatlands is a typical vertical peatland terrestrialization. There are few studies on the plant composition and dynamics of kettle peatlands, especially in freshwater lake wetlands, which lack long-term observations. In this paper, the plant community composition of typical kettle peatlands was observed in the Xingkai Lake area, Heilongjiang and we made strict rules for field investigation, recording and laboratory analysis. This dataset contained the plant community composition, dominant plants, above- and belowground biomass, and plant density in the kettle peatlands from 2012 to 2018. Users can search the data by survey year and plant community composition. On the one hand, this shared the long-term dataset about plant community in kettle peatlands could enrich the peatland plant community dataset. On the other hand, the data can be used as a support for students and researchers working in physical geography and ecology, and as a reference for ecological restoration and sustainable management of wetlands.
