Abstract

Leaf litter decomposition is one of the main carbon release pathways in mangrove forests. Mangrove species and site elevation are important factors for successful restoration of mangrove forests. Carbon sequestration capacity is an important parameter for functional restoration of mangrove ecosystems. The combined influences of mangrove species (Kandelia obovata vs Avicennia marina) and site elevation (low site elevation vs high site elevation) on the carbon release of decomposed leaf litter were seasonally quantified through litterbag method from April 2018 to February 2019. At high elevation site (higher than local mean elevation, 375 cm vs 365 cm), the annual average carbon release of decomposed leaf litter in the A. marina forest (37.04 ± 9.78 g C m⁻², 57.3 %) was significantly higher than that in the K. obovata forest (36.14 ± 8.85 g C m⁻², 52.9 %), because of faster decomposition rate of leaf litter in the A. marina forest. For low elevation site (lower than local mean elevation, 335 cm vs 365 cm), the annual average carbon release of leaf litter in the A. marina forest (33.56 ± 11.33 g C m⁻², 53.2 %) was similar to that in the K. obovata forest (35.65 ± 7.35 g C m⁻², 52.5 %). These results suggested that K. obovata should be selected at high elevation site for mangrove restoration to minimize carbon release in view of carbon release of decomposed leaf litter.

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
