基于Landsat影像的楚雄市2002~2016年植被覆盖度变化研究

Study on the Change of Vegetation Coverage of Chuxiong City from 2002 to 2016 Based on Landsat Image

摘要: 本文基于Landsat卫星影像，提取了楚雄市2002至2016的植被覆盖度变化状况。结果表明：楚雄市植被覆盖大部分是高植被覆盖分布，2002、2005、2009、2013、2016年分别占比54.03%、52.76%、54.72%、54.66%、78.14%，其次为中、中低、低、裸地植被覆盖。十五年来，裸地、低植被覆盖、中低植被覆盖大幅度减少，中植被覆盖变化面积不大。

Abstract: Based on Landsat satellite images, this paper extracted the change of vegetation cover from 2002 to 2016 in Chuxiong City. The results showed that the vegetation cover of Chuxiong City was mostly covered by high vegetation coverage, accounting for 54.03%, 52.76%, 54.72%, 54.66%, and 78.14% respectively in 2002, 2005, 2009, 2013, and 2016, followed by medium vegetation coverage, medium and low vegetation coverage, low vegetation coverage and barren vegetation coverage. In the past fifteen years, barren vegetation coverage, low vegetation coverage and medium and low vegetation coverage have dramatically reduced after fluctuation, while the area of change in medium vegetation coverage was small.
