摘要: 基于2000、2008、2016年3个时相的Landsat影像,采用线性光谱混合分解模型提取了三期的青海湖流域植被覆盖度。结果表明,2000-2008年植被覆盖度有小幅度上升;而2008-2016年则表现出植被覆盖度极明显增加,这一变化与2008年启动的青海湖流域综合治理项目密切相关。

关键词: 青海湖流域, 线性光谱混合分解模型, 植被覆盖变化

Abstract: Based on Landsat images from three phases in 2000,2008 and 2016,the linear spectral mixture model(LSMM) was used to extract the vegetation coverage of the Qinghai Lake Basin in the three phases. The results showed that there was a slight increase in vegetation coverage between 2000 and 2008,while the vegetation coverage indicated a very significant increase during 2008 to 2016,and the increase between 2008 and 2016 was closely related to the Qinghai Lake Basin Comprehensive Restoration Project initiated in 2008.

Key words: Qinghai Lake Basin, linear spectral mixture model, vegetation coverage change
