摘　　要：本研究聚焦于中尼交通廊道建设对周边植被覆盖度(FVC)的影响,FVC是评估交通基础设施建设对植被生态环境影响的重要指标。采用GEE平台处理并分析1992-2022年的数据,利用地理探测器比较分析了自然因素和道路因素对植被的影响。结果显示,2005年前植被覆盖度下降约17%,之后呈上升趋势,2020年达峰值。植被覆盖度随到公路距离呈先减后增趋势,表明人类活动在受自然条件限制时对植被覆盖度有不同影响。地理探测器揭示自然因子是影响植被覆盖度的主要因素,公路距离的影响相对较小。研究结果强调了自然条件在植被生态变化中的主导作用,并为相应生态环境改善提供科学依据。This study examines the impact of China-Nepal transportation corridor construction on Fraction of Vegetation Cover(FVC),a key indicator for evaluating transportation infrastructure's ecological effects on vegetation.Data from 1992 to 2022 were analyzed using the GEE platform.Natural and road factors affecting vegetation were compared using geographic detectors.Findings show a 17%decrease in vegetation cover before 2005,followed by an upward trend peaking in 2020.Vegetation cover trended downward then upward with road distance,suggesting varied human impacts under natural constraints.Geographic detectors highlight natural factors as primary drivers of vegetation cover,with road distance having a minor influence.These results emphasize natural conditions'dominant role in vegetation ecology and offer a scientific basis for environmental improvements.
