中文摘要
      探究生态系统服务价值(ESV)的时空演变规律及其驱动机制,对于深入理解区域生态安全格局构建和人类福祉提升具有重要理论意义和实践价值. 以塔里木河干流为研究区,借助2000~2022年多源数据,在ESV时空变化规律分析的基础上,引入地理收敛交叉映射模型(GCCM)探讨了ESV与驱动因素间的复杂因果关系. 结果表明:①2000~2022年间,研究区ESV呈现波动上升趋势,多年平均ESV为221.5亿元;②研究区ESV空间分布格局呈现以河道为中心向两岸梯度递减的河流廊道效应,且ESV表现为正相关和空间聚集分布,并以高-高、低-低集聚为主;③敏感性分析表明草地生态系统对ESV变化的响应最为显著,是区域ESV增长的核心贡献因子;④GCCM模型验证表明,驱动因子对ESV的影响占主导地位,其中归一化植被指数(NDVI)和土地利用强度(LUI)构成ESV演变的关键驱动因素. 研究结果可为干旱区内陆河流域生态安全屏障建设和可持续发展决策提供科学依据.
英文摘要
      Exploring the spatial and temporal evolution of ecosystem service value (ESV) and its driving mechanism is of great theoretical significance and practical value for the in-depth understanding of the construction of regional ecological security patterns and the enhancement of human well-being. In this study, taking the Tarim River mainstem as the study area, with the help of multi-source data from 2000 to 2022, the complex causal relationship between ESV and drivers was explored by introducing the geographically convergent cross-mapping model (GCCM) based on the analysis of spatial and temporal patterns of changes in ESV. The results showed that: ① ESV in the study area showed a fluctuating upward trend during 2000-2022, with a multi-year average of 22.15 billion yuan. ② The spatial distribution pattern of ESV in the study area showed a river corridor effect centered on the river channel with a gradient decreasing to both banks, and ESV showed positive correlation and spatial aggregation distribution and was dominated by high-high and low-low agglomeration. ③ Sensitivity analysis showed that grassland ecosystems responded most significantly to the changes in ESV and were the core contributors to the regional ESV growth. ④ GCCM model validation showed that the influence of driving factors on ESV was dominant, with normalized difference vegetation index (NDVI) and land use intensity (LUI) constituting the key drivers of ESV evolution. This study provides a scientific basis for the construction of ecological security barriers and sustainable development decision-making in inland river basins in arid zones.
