Spatiotemporal evolution and trade-off synergy of ecosystem service functions in the Tarim Basin Economic Belt
摘要
Abstract
As a crucial ecological functional zone in northwest China,the ecosystem service functions of the Tarim Basin Economic Belt are vital for regional sustainable development.Based on meteorological,topographic,and remote sensing data from 2000 to 2023,this study utilizes the revised wind erosion equation model and the InVEST model to quantitatively evaluate the spatiotemporal evolution patterns of five ecosystem services in the region,including windbreak and sand fixation,soil conservation,carbon storage,water yield,and habitat quality.Furthermore,spatial overlay analysis and bivariate spatial autocorrelation methods were employed to investigate the trade-offs and synergies among these services at multiple scales.The results indicate that(1)From 2000 to 2023,soil conservation and carbon storage generally increased,whereas windbreak and sand fixation and water yield decreased overall;habitat quality remained relatively stable.Spatially,all services exhibited significant het-erogeneity,with notable improvements concentrated in the western and southern regions.(2)Spatial overlay anal-ysis based at a 1 km×1 km grid scale reveals that the correlations among ecosystem services are predominantly characterized by low synergies and strong trade-offs,with a shift in 2005 from dominance of strong trade-offs to prevalence of low synergies.(3)At the 10 km×10 km grid scale,bivariate spatial autocorrelation analysis re-vealed that most pairwise service correlations were synergistic,except for windbreak and sand fixation versus wa-ter yield,which exhibited a dominant trade-off.关键词
