| 摘 要： | 以福建省长汀县河田地区为研究区,在野外样方生物量调查和典型植被光谱测定基础上,对比分析SPOT5影像8种植被指数与马尾松林（Pinus massoniana）碳储量关系,估算区域尺度马尾松林碳储量。结果表明,马尾松林冠层与林下植被芒萁（Dicranopteris dichotoma）在短波红外波段（SWIR）反射率区分明显。加入SWIR的修正的归一化植被指数（MNDVI）与森林碳储量回归决定系数最高,并有较小的均方根误差,同时可减少林下植被覆盖对马尾松林碳储量估算影响。生态恢复驱动下研究区平均碳储量增加到30.37 t/hm2。 |

| Abstract: | The Hetian area of Changting County in Fujian Province was selected as a case to examine the quantitative relationship between eight remote sensing vegetation indices (VIs) and the forest carbon storage in the Hetian area by plot sampling and analysis of biomass allometric equations and SPOT-5 imagery. We then estimated the carbon storage of Pinus massoniana forest for the area. The results show that the spectral reflectance of Pinus massoniana canopy and its understory vegetation, Dicranopteris dichotoma could be clearly distinguished in SWIR(Short Wave Infrared) band. The degree of agreement between the VI and the carbon storage of the forest are different among the eight used indices, with the MNDVI (Modified Normalized Difference Vegetation Index) having the highest R2 value and second smallest RMSE value. The VI constructed with a SWIR band could reduce the overestimation in the forest’s carbon storage caused by the effects of understory vegetation. After 30 years’ effort of management to reduce soil loss in the area, particularly in the past 10 years, the ecologically restored carbon under the Pinus massoniana forest has reached to 30.37 t/hm2 on average. |
