Abstract
Mangroves are the major sink of blue carbon in coastal ecosystems. However, due to high levels of anthropogenic activities, mangroves rapidly disappear worldwide, resulting in a significant loss of carbon stocks. This study aims to quantify the biomass carbon stock of mangroves (standing live trees and roots) and soil organic carbon stocks at six sample sites affected by aquaculture pond expansions in the Barru District, South Sulawesi Province. We investigated the structure and composition of mangrove vegetation at each site in a 20 m × 50 m transect and sampled six soil cores at depths of 0 cm–15 cm, 15 cm–30 cm, 30 cm–50 cm, and 50 cm–100 cm. We used allometric equations for specific species from previous studies to estimate biomass carbon stocks and used the Loss on Ignition method for soil analysis. Based on the carbon stocks value, the mean values of aboveground (tree) and belowground (root) carbon of mangroves were 100.66 ± 23.44 Mg C ha-1 and 2.81 ± 1.16 Mg C ha-1, respectively, while the mean value of soil organic carbon was 570.76 ± 97.70 Mg C ha-1. The over-exploitation of mangrove areas in this region in the last two decades (for various purposes, but mainly related to aquaculture pond development) has resulted in lower blue carbon estimates than in other regions in Indonesia. Therefore, protecting intact mangrove areas and rehabilitating and restoring areas that have been degraded or lost is essential to conserve blue carbon and rebuild and increase carbon stocks to mitigate climate change and ensure mangrove sustainability.
红树林是沿海生态系统中蓝碳的主要储存库。然而,由于高水平的人为活动,红树林在世界范围内迅速消失,导致碳储量的大量损失。本研究旨在量化南苏拉威西省巴鲁地区6个受水产养殖池扩建影响的样点红树林(直立活树和树根)的生物量碳储量和土壤有机碳储量。我们在一个20 m × 50 m的样带上调查了每个样地红树林植被的结构和组成,并在0 cm - 15 cm、15 cm - 30 cm、30 cm - 50 cm和50 cm - 100 cm的深度取样了6个土壤芯。我们利用以往研究中特定物种的异速生长方程来估算生物量碳储量,并利用引燃损失法进行土壤分析。基于碳储量值,红树林地上(树)碳均值为100.66±23.44 Mg C ha-1,地下(根)碳均值为2.81±1.16 Mg C ha-1,土壤有机碳均值为570.76±97.70 Mg C ha-1。过去二十年来,该地区红树林的过度开发(用于各种目的,但主要与水产养殖池塘开发有关)导致蓝碳估算值低于印度尼西亚其他地区。因此,保护完整的红树林地区,恢复和恢复已经退化或丧失的地区,对于保护蓝碳,重建和增加碳储量,以减缓气候变化,确保红树林的可持续性至关重要。
期刊介绍:
Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include:
Physical sedimentology and geomorphology
Geochemistry of the coastal ocean (inorganic and organic)
Marine environment and anthropogenic effects
Interaction of physical dynamics with natural and manmade shoreline features
Benthic, phytoplankton and zooplankton ecology
Coastal water and sediment quality, and ecosystem health
Benthic-pelagic coupling (physical and biogeochemical)
Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles
Estuarine, coastal and shelf sea modelling and process studies.
