基于遥感影像的植被覆盖度统计方法的分析(简报)

Calculation of Vegetation Coverage Based on Remote Sensing Image

采用归一化植被指数(NDVI)建立植被覆盖度的遥感定量模型,并以行政区界市县为单位,对不同区域的覆盖度进行统计分析,通过对海南岛ETM+遥感数据的实际应用,结果表明,利用该方法来定量提取区域内的植被覆盖度是可行的。

Normalized Difference Vegetation Index(NDVI) has been used to build remote sensing quantity models for vegetation coverage,and the way of calculation of mean vegetation coverage was at county level.The values of calculation were used to reflect the vegetation’s temporal situation.The results indicated that this method was feasible for calculation of mean vegetation coverage in Hainan Island.
