Abstract:

The construction of ecological civilization is a critical issue in the current era, and research on the spatiotemporal variations of ecological-economic value and its driving factors is essential for achieving coordinated regional economic growth and ecological protection. Using land-use remote sensing monitoring data from 1983 to 2023, this study applies the equivalent factor method to quantitatively assess ecological-economic value at the county scale in Inner Mongolia, China and to analyze its spatial and temporal evolution. Geodetector and geographically weighted regression models are employed to explore the determinants of spatial differentiation in ecological-economic value. The results indicate that: (1) Land-use types in Inner Mongolia changed significantly between 1983 and 2023, with grassland occupying the largest area and serving as the main source of cultivated land conversion. (2) Ecological economic value declined from 66.34 billion yuan in 1983 to 65.04 billion yuan in 2023, representing a total loss of 1.3 billion yuan. Spatially, ecological economic value exhibited a “high in the north and low in the south” and “high in the east and low in the west” distribution pattern. (3) Average annual temperature and the normalized difference vegetation index (NDVI) were the dominant factors influencing ecological-economic value. Temperature showed a negative correlation, while NDVI was positively correlated, increasing from west to east. These findings provide a scientific reference for developing ecological protection policies in Inner Mongolia. Future efforts should emphasize balancing the transformation among different land-use types to promote the synergistic advancement of economic development and ecological protection.
