Abstract:

The Shanxi central urban agglomeration is the region with the best economic development in that province. However, this economic growth is accompanied by varying degrees of damage to the ecosystem. Based on the evolution of land use patterns, methods such as the InVEST model, ArcGIS, pixel statistical analysis and the four-quadrant model to assess the spatiotemporal patterns and trade-offs/synergies of water yield, food provision, soil conservation, and carbon storage services from 2000 to 2020, and to analyze in depth the impact of land use patterns on ecosystem services. The results showed that (1) Shanxi central urban agglomeration services of water yield, food supply, and soil retention elevated over the years, while carbon storage diminished marginally, with significant discrepancies in the ecosystem service capacities across various land types and administrative regions. (2) Ecosystem services overall are primarily characterized by synergistic relationships; food supply, water yield, and soil conservation are synergistic, whereas all maintain a trade-off relationship with carbon storage. (3) Expansion of built-up land positively impacts water yield, increased forest land promotes soil conservation, while reduction of forest and grassland negatively impacts carbon storage. Land use intensity was positively correlated with water yield, food supply, and soil retention, yet adversely affected carbon storage. These findings provide critical reference points for the ecological security and sustainable development of Shanxi central urban agglomeration and other similar regions.
