基于Landsat 的三江源区植被覆盖时空变化分析.

This paper analyzed the spatial and temporal variation characteristics of the vegetation coverage based on FVC inversed by dimidiate pixel model using Landsat data of 2001, 2010 and 2015 in Zeku County of Three-River Source Region. The results indicate that the high vegetation coverage distributes in east and south, and the low vegetation coverage distributes in northwest. The vegetation coverage had been significantly improved in 2001-2015 and has the trend to medium and high coverage. The uptrend is mainly distributed in mid-east and the downtrend is mainly distributed in mid-north and southwest. The higher vegetation coverage grade gradually becomes the superiority landscape and the ecological engineering and the human activities of Three-River source region has some influence to the improvement of vegetation coverage of the study area.
