| 摘 要： | 利用FIAASH对中山陵风景区的ETM+影像进行大气校正,然后利用ETM+原始DN值、大气表观反射率、地面反射率计算归一化植被指数,并分别建立不同方法计算的归一化植被指数与单位蓄积量的函数关系。研究结果表明,地面反射率计算的归一化植被指数更能反映地面植被覆盖的真实情况,同蓄积量有更强的相关关系。

| Abstract: | By applying the FLAASH,ETM+ image of landscape district of Sun Yat-sen mausoleum was corrected for atmospheric effects to generate the apparent reflectance and the surface reflectance products.After applying the DN image,apparent reflectance image and surface reflectance image to cal- culate the NDVIs,the functional correlations were built between those NDVIs and forest volume with different functions.It was found that NDVI calculated from surface reflectance had the best correlation with forest volume and could truly show vegetation cover of surface. |
