Multi-Scenario Land Use/Cover Change and Its Impact on Carbon Storage Based on the Coupled GMOP-PLUS-InVEST Model in the Hexi Corridor, China
The results demonstrate that LUCC significantly influences carbon storage values. Utilizing the “GMOP-PLUS-InVEST” integrated approach effectively refines the structure of LUCC, achieving optimization targets for quantity and spatial arrangement. This enhancement boosts both ecosystem value and economic returns, promoting their balanced progress. In the 2035 land use simulation for the Hexi Corridor, the estimated carbon storage under both scenarios exceeded the 2020 levels. Additionally, the ECS, facilitated by the “GMOP-PLUS-InVEST” framework, successfully maximized both ecological and economic benefits, further exemplifying the capacity of the framework to optimize land use and enhance these benefits.
4.1. Analysis of the Response of Carbon Storage to LUCC in Hexi Corridor from 2000 to 2020
4.3. Limitations, Prospects, and Policy Recommendations
The Hexi Corridor region, selected for this study, is, to some extent, representative of arid and semi-arid areas in China. Future studies can extend the “GMOP-PLUS-InVEST” framework to encompass all arid and semi-arid regions, including the Loess Plateau. For a more precise simulation of carbon storage, land use categories should be further refined and more accurate carbon density data should be employed in actual sampling. Additionally, the objective functions, constraints, and optimization scenarios within the GMOP framework can be adapted based on the specific circumstances of the study area to enhance the accuracy of simulations.
The Hexi Corridor is an important ecological security barrier in China, as well as an important dry farming production area and advanced manufacturing base in Gansu Province; in this light, this study proposes the following four policy recommendations:
(2) In the ECS, arable land emerges as a significant potential carbon storage type. Recognizing its dual role in food production and ecological protection, strategies should involve expanding arable land and implementing effective farmland management. This can include establishing multifunctional farmlands (e.g., farmland with interspersed trees) and employing ecological agricultural practices like straw returning to enhance carbon storage and soil water retention.
(3) The study from 2000 to 2035 indicates that although construction land contributes minimally to regional carbon storage, its uncontrolled expansion (often encroaching on arable land) can lead to significant carbon loss. Thus, promoting urban blue–green networks and optimizing urban space buildings are critical. These measures will not only increase the happiness of residents but also augment the carbon storage level in urban spaces and reduce carbon emissions.
(4) The water area of the Hexi Corridor is small, but because the Hexi Corridor is located in an arid and semi-arid region, regional water resource management is of great significance for agricultural cultivation and urban development, and the significance of the water area to the Hexi Corridor is not limited to its direct carbon storage capacity. Therefore, it is necessary to further strengthen the protection of lake and wetland water resources and carry out water quality testing to strengthen the role of water areas in maintaining regional ecological stability.
