Abstract:

This research integrates the Flus-Markov model and the equivalent factor method to analyze dynamic changes in the land use patterns in the Tarim River Basin from 2012 to 2032, evaluate the spatiotemporal characteristics of ecosystem service value (ESV), and predict its future trends, based on Landsat remote sensing images and socioeconomic data. The results show that: (1) From 2012 to 2032, the area of unused land and water first decreased and then increased, while the cultivated land area expanded and grassland degraded significantly continuously, resulting in a decrease of 2093.72×108 yuan in the total ESV. The contributions of grassland and water decreased by 2984.17×108 yuan and 38.44×108 yuan, respectively. (2) The spatial distribution of ESV shows a significant gradient, decreasing from high values in the northwest to low values in the southeast. Hydrological regulation, climate regulation, and gas regulation are key service functions. (3) Sensitivity analysis shows that changes in water bodies and grasslands have the greatest impact on ESV. A low value of the elasticity of coefficient correction indicates that the estimation results are robust. Model validation reveals a Kappa coefficient of 0.95, indicating reliable prediction accuracy. (4) Land use and normalized difference vegetation index are the main factors influencing the ESV of the Tarim River Basin. This study reveals the correlation between the degradation of ecological service functions and increased land use in the Tarim River Basin. ESV could be improved by optimizing land use structure, strengthening grassland and water conservation, and providing a scientific basis for ecological security and sustainable development in arid areas.
