| 中文摘要 |
| 塔里木河流域是我国生态环境较为脆弱的流域之一，明晰其生态环境变化趋势和驱动机制对塔里木河流域生态环境保护和可持续发展具有重要意义. 根据塔里木河流域沙漠化和盐碱化较为严重的生态环境特性，提出改进遥感生态指数（MRSEI）模型对塔里木河流域生态环境质量进行综合评价，并通过Sen+Mann-Kendall趋势分析和参数最优地理探测器探究研究区生态环境质量变化趋势以及主要驱动因子. 结果表明：①研究区2000年、2005年、2010年、2015年和2020年平均MRSEI为0.269、0.248、0.273、0.287和0.280，呈现波动上升趋势，空间分布上东北部沙漠地区生态环境质量较差，其他地区自中部随海拔的向外升高生态环境质量水平也逐渐提高；②2000~2020年研究区生态环境质量的空间变化趋势中，极显著下降、显著下降、轻微下降、极显著上升、显著上升和轻微上升面积占比分别为0.69%、2.5%、43.58%、0.93%、3.66%和48.65%，其中轻微上升和轻微下降面积占比最大，占研究区总面积92.23%，表明塔里木河流域从2000~2020年生态环境质量变化幅度并不明显，以轻微变化为主；③蒸散发、土地利用类型和海拔是塔里木河流域生态环境质量变化的主要单因素驱动力因素，土地利用类型∩蒸散发量是最强交互驱动因子，对流域生态环境质量变化起关键作用. 研究结果证明了2000~2020年间对塔里木河流域生态综合治理的有效性，同时为进一步流域可持续发展和生态环境监测提供了科学依据. |

| The Tarim River Basin is one of the most fragile ecological basins in China， and it is of great significance to clarify the trend and driving mechanism of its ecological changes for environmental protection and sustainable development. Based on the ecological characteristics of the Tarim River Basin， which has severe desertification and salinization problems， we proposed a modified remote sensing ecological index （MRSEI） model to comprehensively evaluate the ecological quality of the Tarim River Basin. Furthermore， we explored the trend of the ecological quality and the main driving factors in the study area through the Sen+Mann-Kendall trend analysis and the optimal parameters-based geographical detector. The results showed that： ① The average MRSEI of the study area in 2000， 2005， 2010， 2015， and 2020 was 0.269， 0.248， 0.273， 0.287， and 0.280， respectively， showing a fluctuating upward trend. The spatial distribution of the desert area in the northeast was poorer in terms of ecological quality， whereas the level of ecological quality in other areas from the central region increased gradually with the outward elevation. ② Within the spatial change trend of ecological environment quality in the study area from 2000 to 2020， the proportions of the area with a highly significant decrease， significant decrease， slight decrease， highly significant increase， a significant increase， and slight increase were 0.69%， 2.5%， 43.58%， 0.93%， 3.66%， and 48.65% respectively. The proportion of the area with a slight increase and slight decrease were the largest， accounting for 92.23% of the total area of the study area， indicating that the ecological environment quality of the Tarim River Basin did not change significantly from 2000 to 2020， with slight dominating changes. ③ Evapotranspiration， land use type with elevation was the main single-factor drivers of ecological and environmental quality changes in the Tarim River Basin. Moreover， the land use type with evapotranspiration was the strongest interactive driver， which played a crucial role in ecological and environmental quality changes in the basin. This study demonstrated the effectiveness of the comprehensive ecological management of the Tarim River Basin during the period of 2000-2020 and provides a scientific basis for further sustainable development of the basin and ecological environment monitoring. |
