摘　　要：以海南岛接收的2003-2005年接收的MODIS遥感数据为基础,通过提取归一化植被指数,分析了多年来海南岛植被指数变化的时空分布规律。由于海南岛植被指数空间变化特征与温度有着密切关系,借助NDVI-Ts空间特征分析了海南岛7个代表性区域的植被覆盖的情况,并与实际情况进行了对比,结果表明:通过遥感数据反演NDVI-Ts空间特征分析能适合海南岛地区植被覆盖范围的确定,为今后热带地区利用NDVI和地表温度(Ts)确定植被覆盖类型提供了一种有效的方法。The spatial distribution of NDVI in Hainan island was studied by analysis of the MODIS data from 2003 to 2005. For the NDVI spatial change characteristic was relative with temperature, so NDVI-Ts was applied to study the vegetation cover in seven representative areas of Hainan island by compared with the real data of these cities. The results indicated that NDVI- Ts was fit to study tropical area vegetation cover, at the same breath ,which will be a good way to study vegetation cover in tropical region by NDVI and surface temperature.
