The dataset comprises monitoring data from three typical vegetation communities in the Dongting Lake wetland ecosystem: the Carex soil biological sampling site in the comprehensive observation field, the Southern Cattail soil biological sampling site, and the Water Knotweed soil biological sampling site in the supplementary observation field. The monitoring of Dongting Lake beach vegetation is conducted on a plot basis. To ensure spatial representativeness of the data, five replicated sampling areas are established for each community type in each monitoring session. The monitoring is conducted around the mid-month of each month during the non-flood period, with slight variations depending on weather conditions. Due to different flood fluctuations, the number of monitoring sessions varies each year. For this dataset, data from February, April, October, and December of each year were selected. However, in October 2012 and 2015, the monitoring plots had not fully receded due to high water levels, so data from November were chosen instead. The aboveground biomass of the vegetation communities is calculated based on species-specific survey data conducted within 1m x 1m plots. For some species, their biomass is too small to be accurately measured, resulting in either non-sampling or recording of the total biomass of the plot, with an explanation provided in the remarks field.Citation(s)
