How much carbon is stored in Dongting Lake?

With the removal of Poplar forests, the average carbon storage capacity decreased in Dongting Lake. The unit carbon storage was 108.58 MG/ha, 96.32 MG/ha, and 84.65 MG/ha in 2014, 2017, and 2021, respectively (Figure S1d, S1e, and S1f).

Why is the Dongting Lake basin important?

The Dongting Lake Basin is an important hydrological regulation and flood storage area in the Yangtze River Basin, which plays an important role in maintaining regional ecological security. The watershed vegetation and its carbon sequestration capacity have changed dramatically due to climate change and human activities in the last two decades.

Is the water area of Dongting Lake stable?

However, apart from the substantial contraction observed in 2006, the water area of Dongting Lake remained relatively stable in the other years studied. Table 2. Changes in the Water Area of Dongting Lake from 2005 to 2020. Fig. 3. Time evolution of Dongting Lake. Fig. 4. Spatial evolution of Dongting Lake from 2005 to 2020. 5.1.2.

What are the ESS outcomes in Dongting Lake?

Using Dongting Lake as a case study, this study systematically evaluated the ESS outcomes by quantifying three key ESSs, including water conservation, carbon storage, and habitat quality before, during, and after the implementation of the PERP.

How much water is conserved in Dongting Lake?

With the changes in wetland type, Dongting Lake exhibited different characteristics in terms of overall water conservation (Table 4). The total water conservation amounts were 1.61 km 3, 1.53 km 3, and 1.60 km 3 for 2014, 2017, and 2021, respectively.

Does Dongting Lake have a more concentrated centre of gravity during dry season?

Conversely, during the dry season, it was primarily concentrated in the northwest-lower direction of Nandashan Town, suggesting that compared to the flood season, Dongting Lake exhibited a more concentrated centre of gravity during the dry season, indicating relatively minor migration or changes in its centre of gravity.
