利用多时相中分辨率卫星影像监测-福建省植被覆盖变化

植被指数能定量地反映植被的变化信息，利用2001～2005年的EOS/MODIS卫星遥感资料，通过基于增强型植被指数的植被覆盖度计算模式，得到2001～2005年福建省植被覆盖度的年际动态变化情况，分析结果表明：福建省植被覆盖存在有不同程度的退化现象，退化最明显的地区出现在居民点、河流两岸、海岸带和岛屿等区域，植被覆盖变化在整体上呈现出内陆普遍小于沿海地区的特征，而远离沿海特别是内陆海拔较高的山区，植被覆盖变化很小，反映出研究区内植被覆盖受人类活动影响相对较大的事实。

Monitoring Vegetation Coverage Change of Fujian Using Multi-temporal Remote Sensing Image

It has being more and more noticed that vegetation coverage change impact on ecological environment protection. The vegetation index which can quantificationally indicate vegetation coverage change are researched. Taking Fujian province as demonstration, the vegetation coverage index which based on model of enhance vegetation index are calculated every year by using EOS/MODIS data during 2001～2005, and the interannual dynamic change of vegetation coverage index in Fujian province are analysed. The results show that there are different degradation phenomena of vegetation coverage in different regions,and that the vegetation coverage degradation in residential area, sides of river, coastal region and island are most apparent. The change of vegetation coverage away from ocean is less apparent than that near ocean, especially in mountainous area. This shows the fact that the changes of vegetation coverage in Fujian province are mainly affected by human activities.
