摘　　要：以RS和GIS为技术支撑,基于改进的CASA模型为基础,利用MODIS数据、森林资源清查毛竹样地数据、气象数据及DEM数据等,估算了2012年福建省毛竹林NPP。结果表明,毛竹林最大光能利用率为2.399 6g C/MJ,2012年福建省毛竹林NPP平均值为1 169.10 g C/(m2!a),毛竹林碳积累总量为1.034 4×109t C。Based on improved CASA mode and technology of RS and GIS, by using data from MODIS, Phyl- lostachys edulis samples of National Forest Resources Inventory, meteorology and DEM, Phyllostachys edulis net primary production （NPP） of Fujian province in 2012 was estimated in this study. The results showed that the maximum energy efficiency of Phyllostachys edulis forest was 2. 399 6gC/MJ, the amount of carbon accumulation of Phyllostachys edulis forest in Fujian province was 1. 034 4×10^9tC, the average NPP was 1 169. 10 gC/ （m2.a） in 2012.
