摘要
长江三峡工程建成后,广泛而深远地影响了周围生态环境。本文基于长时序Landsat TM/ETM/OLI影像,对三峡库区近25年来(1998—2017)的植被指数、植被覆盖度、地表温度、不透水层覆盖度指数进行遥感提取反演,制作专题地图,对其时空演化、分布规律和影响机制进行分析。
After the completion of the Three Gorges Project on the Yangtze River,it has extensively and profoundly affected the surrounding ecological environment.Based on the long-time series Landsat TM/ETM/OLI images,this paper extracts and retrieves the vegetation index,vegetation coverage,surface temperature,and impervious layer coverage index of the Three Gorges Reservoir in the past 25 years(1998-2017),produces thematic maps,and analyzes its temporal and spatial evolution,distribution law and influence mechanism.
