摘　　要：温度、降水和地表覆盖是影响植被指数变化的主导因子,但在不同区域内不同因子对植被指数的影响程度有所不同。海南岛地处独特的热带区域,为弄清温度、降水和地表覆盖对海南岛植被指数的影响,根据MODIS遥感数据,提取了2004年海南岛的月平均植被指数集,采用了相关分析的方法,探讨了海南岛植被指数变化与其驱动因子(温度、降水和地表覆盖)的关系。结果发现海南岛植被指数的变化受温度的影响大于降水作用的影响,而降水作用的影响又大于地表覆盖的驱动作用。Temperature, precipitation, land-cove are the main factors which effect the change of vegetation index, but the effect to vegetation index is not same in different place. Hainan island locate in tropic , in order to know the relation of temperature, precipitation, land-cove with vegetation index, on the basis of research on vegetation index based on MODIS, the driving factors of temperature, precipitation, land-cover which effected the vegetation index change was analyzed by correlation analysis method. The conclusions are that the changes of vegetation index effected by temperature which higher than precipitation, and precipitation higher than land-cover in Hainan Island.
