风云三号气象卫星在海南橡胶林遥感监测中的应用

Application of FY-3 Meteorological Satellite in Monitoring Remote Sensing of Rubber Plantation in Hainan Island

基于近4 a的FY-3晴空遥感数据,采用Savitzky-Golay滤波方法计算海南橡胶林种植区逐旬的NDVI,建立橡胶林不同年份的橡胶周年生长植被指数变化曲线。在植被指数序列的基础上,通过NDVI值的变化值与此时段橡胶NDVI值的变化值的标准方差的比较,建立了海南橡胶气象灾害损失等级标准。实现了FY-3气象卫星数据在海南天然橡胶林遥感长势动态监测中的应用。

NDVI of ten days were calculated by the Savitzky-Golay filtering method and vegetation index change curve of rubber annual growth in different years were established based on the FY-3 remote sensing data in2009-2012.The loss grade standard of meteorological disasters of rubber plant was established by comparing with the changing the NDVI values and the standard variance of rubber NDVI values based on vegetation index time series.The research results would provide a technical support for the remote sensing dynamic monitoring of rubber growth changes in Hainan rubber plantation area by FY-3 meteorological satellite data.
