摘要:

从物种组成、群落结构和物种多样性等角度, 以周边天然红树林为参照, 对海南东寨港人工退塘还林、人工辅助退塘还林和自然修复3种修复模式的修复效果进行了比较分析, 为退塘还林工程提供参考与数据支撑。经过25年的修复, 研究区调查到红树植物16种, 人工退塘还林修复模式群落的红树林物种数量最多。各修复模式的群落结构发育良好, 桐花树(Aegiceras corniculatum)、海莲(Bruguiera sexangula)和无瓣海桑(Sonneratia apetala)为区域分布优势种, 其中桐花树和海莲为旺盛增长种群、更新潜力大。退塘还林生态修复区域将向着以海莲、桐花树等自然更新树种为主的方向演替, 逐渐达到乡土红树植物的生态恢复。从物种多样性指数来看, 人工退塘还林模式和人工辅助退塘还林模式的群落复杂程度及物种均匀度一定程度高于自然修复模式和天然林, 适当的人为干扰在早期可以增加红树林修复群落的生物多样性。退塘还林工程中可综合考虑立地条件、成本费用等因素, 优先选择人工辅助退塘还林方式, 促进红树林植被恢复、增加群落物种多样性, 以快速重建良好的红树林湿地生态系统。

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.
