摘要:

环塔里木经济带作为我国西北关键生态功能区,其生态系统服务功能对区域可持续发展至关重要。基于2000—2023年气象、地形与遥感数据,综合运用修正风蚀方程(RWEQ)模型与InVEST模型,定量评估了该地区防风固沙量、土壤保持量、碳储量、产水量及生境质量5项生态系统服务的时空演变规律,并借助空间叠置分析与双变量空间自相关方法深入探究了服务间权衡协同关系的空间格局。结果表明:(1) 2000—2023年研究区土壤保持量和碳储量总体呈上升趋势,防风固沙量和产水量总体呈下降趋势,生境质量基本稳定;空间上,各项服务均表现出显著异质性,增长区主要集中于西部和南部。(2) 基于1 km×1 km栅格尺度的空间叠置分析显示,生态系统服务间关系以低协同与强权衡为主导,且该主导格局在2005年发生根本性逆转,由强权衡绝对优势转变为低协同主导。(3) 在10 km×10 km栅格尺度上,双变量空间自相关分析揭示两两服务间关系以协同为主,仅防风固沙量与产水量之间以权衡关系为主导。

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 heterogeneity, with notable improvements concentrated in the western and southern regions. (2) Spatial overlay analysis 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 revealed that most pairwise service correlations were synergistic, except for windbreak and sand fixation versus water yield, which exhibited a dominant trade-off.
