植被指数变化与地表反照率的关系研究——以海南岛西部为例

Study on Relationship between Vegetation Index Change and Surface Albedo

利用ETM+遥感数据研究海南岛西部植被指数与地表反照率的关系。结果表明,在沙化严重区域地表反照率与植被指数存在负相关,而在高植被覆盖度区域两者存在幂函数关系。

The relationship between vegetation index and surface albedo in west of Hainan island was studied with ETM ＋ remote sensing data. The results showed that there was a negative correlation between surface albedo and vegetation index in desertification serious areas and there was a power function relationship between them in area with high vegetation coverage.
