| 英文摘要 | The ecological impacts of roads in permafrost regions remain poorly understood, particularly at small and medium scale, limiting effective conservation and road management strategies. We propose a multi-scale remote sensing-based paradigm to quantify these impacts throughout road construction and operation. Using spatial deviation (D), change rate (I), and Road Ecological Impact Index (REII), we assessed the Gongyu Expressway, the first expressway on the Tibetan Plateau. Results show that surface water and vegetation impacts extended up to 100 m, with seasonal variations: rainy season effects were 4-6 times stronger, and construction impacts exceeded operation impacts by 1.1-1.4 times. Monthly impact amplitudes surpassed annual values, highlighting intensified short-term variations. Our paradigm enables rapid, high-precision monitoring of road-induced ecosystem stresses, reducing time lags in ecological assessment. Given the sensitivity of permafrost environments, this approach is crucial for predicting and mitigating the long-term ecological effects of expanding expressway networks. |
