| 中文摘要: |
| 基于谷歌地球引擎（GEE），采用太原市2001—2022年的Landsat遥感影像，建立遥感生态指数（RSEI），利用Theil-Sen median 趋势分析法、Mann-Kendall检验、空间转移矩阵和地理探测器分析该市生态环境的变化趋势和影响因素。结果表明：太原市2001—2022年RSEI平均值为055，生态质量水平表现为中等；研究期间太原市RSEI发生了“良好→中等”“优→良好”“中等→较差”“较差→差”的变化，其生态环境质量整体变差；归一化植被指数、净生态系统生产力、缨帽变换湿度分量、年总降水、高程、年总太阳辐射、年最高温与RSEI呈正相关关系，地表温度和干度与RSEI呈负相关关系；各因素对生态环境质量的定量影响尚不明确，改善太原市生态环境质量须结合地形、植被覆盖、气候等因素进行综合治理。 |

| Based on Google Earth Engine and Landsat remote sensing images of Taiyuan from 2001 to 2022， the remote sensing ecological index（RSEI） was establish. The changing trends and influencing factors of the citys ecological environment were analyzed by Theil Sen median trend analysis， Mann Kendall test， spatial transition matrix and geographic detectors. The results indicated that the average RSEI of Taiyuan from 2001 to 2022 was 055， and the ecological quality level was medium. During the research period， the RSEI in Taiyuan underwent changes from “good to medium” “excellent to good” “medium to poor” and “poor to poor”， and the overall ecological environment quality deteriorated. The RSEI was positively correlated with normalized difference vegetation index（NDVI）， net ecosystem productivity（NEP）， wetness component of tasseled cap transform， annual total precipitation， elevation， annual total solar radiation， annual highest temperature， and negatively correlated with surface temperature（LST） and dryness（NDBSI）. The quantitative impact of various factors on the ecological environment quality was still unclear. To improve 〖GK!86mm〗the ecological environment quality of Taiyuan， comprehensive management must be carried out in combination with factors such as terrain， vegetation coverage and climate. |
