A Study on the Evolution of Mangrove Forests along the Maritime Silk Road from the Perspective ofScale and Morphology |
LIU Zhaoqi,,HE Fang* |
Abstract: |
Against the backdrop of China's efforts to promote cooperation along the
Maritime Silk Road and establish the "International Mangrove Management Center"
to serve all signatory countries, particularly developing nations, this study explores
the challenges of managing and monitoring mangroves along the Maritime Silk Road.
Specifically, it addresses the issues of "quantity over quality" and "scale effects".
The scale effect refers to the phenomenon where spatial data analysis results change
as the observation grain size changes, making certain spatially sensitive landscape
ecology indicators difficult to apply in cross-country comparisons. To address these
challenges, this study proposes an observation framework from the perspective of
mangrove community size and landscape morphology characteristics. The study
focuses on scale metrics and uses multi-scale self-similar fractal dimensions to reflect
the growth form and quality of mangroves. It combines methods such as the gradient
grid method, Hausdorff dimension, and spatial statistical analysis to verify the fractal
characteristics and robustness of mangrove indicators. By reviewing the evolution
trends of mangrove size and fractal dimensions across 40 countries along the Maritime
Silk Road since the 21st century, this research reveals that in terms of scale, the past
20 years have witnessed a coexistence of overall mangrove area decline and localized
growth in these regions. In terms of morphology, the structural changes in coreperiphery
mangrove communities at the national level are identified as the main cause
of fractal fluctuations in mangroves. Based on these findings, the study classifies the
degradation risks of mangroves in different countries along the Maritime Silk Road
into four categories: low-risk regions for both scale and morphology, low-risk scale but
high-risk morphology regions, high-risk scale but low-risk morphology regions, and
high-risk regions for both scale and morphology. It also explores the spatiotemporal
response of mangrove size and morphology to human societal development. The
results show that macro factors such as population, economy, and urbanization
directly impact mangrove size, while a correlation exists between malnutrition rates
and mangrove morphology degradation. Human activity, as a driving force behind the
evolution of mangrove scale and morphology, can have both negative and positive
effects, depending on whether effective conservation measures are implemented and
whether the mobilization of broad societal efforts can be achieved. The study further
discovers feasible cases where the negative correlation between human footprints
and mangrove community scale evolution has been "decoupled" and can even
revert to "re-coupling" in a positive direction, as exemplified by Shenzhen, China.
The study's findings further reinforce the role of mangroves in providing livelihood
resources such as food and fuel for surrounding communities in some Maritime Silk
Road countries. Research indicates that since the 21st century, nearly half of global
mangrove loss attributable to land use changes driven by livelihood needs, including
rice cultivation, aquaculture, and the cultivation of economic crops like oil palm.
The morphological analysis conducted in this study reveals that the edge and smallscale
mangrove communities are particularly vulnerable to the impacts of agriculture
and aquaculture. Thus, The integration of sustainable mangrove conservation with
agricultural production and livelihood resource acquisition is imperative. Only
by aligning sustainable livelihood practices with sustainable shifts in agricultural
production can the degradation of mangrove scale and morphology due to overexploitation
be effectively avoided. Lastly, the study examines international models
for mangrove governance, including regional cooperative governance, governmentled
legislative frameworks, green technology support, and community empowerment
and participation models. Several governance directions suitable for countries along
the Maritime Silk Road are proposed. These strategies include: 1) Joint management
of negative environmental externalities between neighboring countries, beginning
with non-binding cooperation mechanisms and advancing to parallel bilateral and
multilateral cooperation efforts, with the potential to foster environmental cooperation
even amidst political deadlock; 2) The sharing of mangrove management experiences
and technologies among rapidly urbanizing nations, including legislative and technical
knowledge; and 3) The effective integration of governance frameworks involving
international institutions, local governments, society, and businesses is crucial for
addressing cooperation content, forms, and power structures. These strategies not
only contribute to the overall protection of mangrove quantity but also provide viable
pathways for safeguarding the structural integrity of mangrove morphology. In
summary, this study provides theoretical support for the coordinated monitoring and
management of mangroves in countries along the Maritime Silk Road, contributing
to both the preservation of mangrove quantity and the protection of their structural
characteristics |
