Abstract:

The study provides a reference for the pond-to-mangrove project through comparing the restoration effects of three restoration models in Dongzhaigang, Hainan, from the perspectives of species composition, community structure, and species diversity, using natural mangrove forests as a control. After 25 years of restoration, there were a total of 16 species of mangrove plants in the study area, with the highest species richness observed in the artificial pond-to-mangrove restoration model. The community structure of the three restoration models was well developed, with Aegiceras corniculatum, Bruguiera sexangula, and Sonneratia apetala being the dominant species in the area. Aegiceras corniculatum and Bruguiera sexangula were the species with vigorously growing population and great renewal potential. With the development of the community, the pond-to-mangrove area is expected to transition toward dominance by native tree species such as Bruguiera sexangula and Aegiceras corniculatum for renewal and succession. From the perspective of the community complexity, individual plant densities in both artificial pond-to-mangrove and artificially assisted pond-to-mangrove models were found, to some extent, to be higher than those of the natural restoration model and natural mangrove. In the pond-to-mangrove project, based on site conditions and cost, appropriate artificial assistance could be prioritized to accelerate the restoration process of mangrove vegetation and increase community species diversity so that a healthy mangrove wetland ecosystem is rebuilt quickly.
