Spatial-temporal Evolution and Prediction of Ecosystem Carbon Storage on Hainan Island by Coupling InVEST and FLUS Models
[Objective] The influence of land use changes on carbon storage were studied under the expansion of urbanization in Hainan Island to reveal the spatial-temporal evolution pattern of carbon storage and to predict future development trends in order to provide scientific evidence for optimizing the spatial layout of the national territory and for protecting ecologically sensitive areas. [Methods] Based on land use data from 1980 to 2020
this research showed the spatial-temporal changes of carbon storage for Hannan Island. The data were used with the carbon storage module of the InVEST model. The FLUS model and the InVEST model were coupled to simulate land use and carbon storage changes for Hainan Island in 2030 under three scenarios: the natural development scenario
the rapid development scenario
and the ecological protection scenario. [Results] ① The main types of land use on Hainan Island were forest land and cultivated land. From 1980 to 2020
the areas of cultivated land
grassland
forest land
and unused land decreased to varying degrees. The area of construction land and water increased over that time period
with the fastest growth rate being 83.4% for construction land. ② Carbon storage for Hainan Island was generally characterized as “higher in the middle and lower in the surrounding areas”. Carbon storage changed slightly from 1980 to 2000
with a decrease of about 0.03%. From 2000 to 2020
the urbanization process on Hainan Island accelerated
and the loss of carbon storage also increased. The average annual loss was about 372 t
and the cumulative loss of carbon storage was 7 439 t. ③ The prediction results showed that construction land will continue to expand in the future
and carbon storage on Hainan Island in 2030 will decrease under the three scenarios. Under the rapid development scenario
the land use change of construction land was the largest
and carbon storage was the most vulnerable to loss
followed by the natural development scenario. The ecological protection scenario had the smallest change. [Conclusion] Land Use Planning for Hainan Free Trade Port in the future should focus on the protecting key ecological areas such as the central mountainous areas
strengthening the nature reserves of Hainan Island
optimizing the land use pattern
and strictly controlling the transformation of forest land
cultivated land
and wetlands into construction land. The efficiency of carbon sequestration should be improved
and forest carbon sinks should be increased to achieve regional sustainable development.
