摘要

红树林湿地生态系统在碳中和和海岸保护方面具有重要的生态服务功能。近几十年来，一系列的人工红树林湿地已经形成。然而，这类红树林湿地的可持续性还没有得到充分的研究，特别是在景观尺度上。本研究为评估红树林景观的可持续性探索了一套稳健且可移植的技术程序。在谷歌Earth Engine （GEE）云平台的支持下，获得了1990 - 2023年洛阳江口人工红树林的时空演变格局。景观指数由Fragstats计算，并通过Spearman等级相关系数筛选，得到9个关键指标。采用景观指标法和主成分分析法计算了景观可持续发展指数（LSDI），对红树林生态系统的可持续性进行了评价。从PCA得分中得出的LSDI为红树林保护和恢复工作的有效性提供了见解。从1990年到2023年，洛阳江湿地的可持续能力逐渐增强。这一趋势表明，该地区的生态稳定性和恢复力正在朝着积极的方向发展。这些研究结果有助于中国实现碳峰值和碳中和的战略目标，为生态工程提供理论见解和实践建议。

Assessment of wetland sustainability capacity of artificial mangrove wetland on landscape scale: A case of Luoyangjiang River Estuary, China

Mangrove wetland ecosystem plays a vital ecological service function in carbon neutralization and coastal protection. In recent decades, a series of artificial mangrove wetlands have been produced. However, the sustainability of these kind of mangrove wetlands has not been fully studied, especially on the landscape scale. This study explored a set of robust and transplantable technical routines for assessing the sustainability of mangrove forest landscape. With the support of the Google Earth Engine (GEE) cloud platform, the temporal and spatial evolution pattern of artificial mangroves in the Luoyangjiang River estuary was obtained from 1990 to 2023. The landscape index is calculated by Fragstats and screened by the Spearman rank correlation coefficient, and 9 key indicators are obtained. The Landscape Sustainability Development Index (LSDI) was calculated using landscape metrics and principal component analysis (PCA) to assess the sustainability of mangrove ecosystems. The LSDI derived from PCA scores, provides insights into the effectiveness of mangrove conservation and restoration efforts. From 1990 to 2023, the sustainability capacity of the Luoyangjiang wetland, as indicated by LSDI, has gradually increased. This trend suggests a positive trajectory towards enhanced ecological stability and resilience in the region. These findings contribute to the strategic objectives of carbon peaking and carbon neutrality in China, offering both theoretical insights and practical recommendations for ecological engineering.

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.
