摘要:
 以福建省2006年和2012年2期森林资源清查数据、气象数据、MODIS影像(2012)及DEM数据为基础,利用地面调查数据,对毛竹最大光能利用率参数进行测定,基于改进的CASA模型为基础,估算了2012年福建省毛竹NPP,并对其分布规律进行了分析。结果表明:毛竹最大光能利用率为2.399 6 gC·MJ-1,NPP平均值为1 169.10 gC·m-2·a-1,毛竹碳累积量为1.034 4×109tC,毛竹NPP季节性变化明显,秋季>夏季>冬季>春季,分别为45.51%、31.1%、13.8%、9.59%。不仅完善了国内主要植被类型(毛竹)的最大光能利用率参数的测定而且为区域尺度毛竹NPP估算及碳汇定量评价提供科学参考。
Abstract:
 Based on the data from forest inventories in 2006 and 2012,meteorological data,MODIS,DEM and ground survey,the maximum energy efficiency of Phyllostachys heterocycla cv.pubescens was calculated for the first time in this study in Fujian Province.The net primary production (NPP) of P.heterocycla cv.pubescens in Fujian,and its spatiotemporal distribution in 2012 were estimated based on improved CASA model.The results showed that the maximum energy efficiency of P.heterocycla cv.pubescens plantation was 2.399 6 gC·MJ-1,the amount of carbon accumulation was 1.034 4×109 tC,in 2012,the average of P.heterocycla cv.pubescens NPP was 1 169.10 gC·m-2·a-1,and the NPP of P.heterocycla cv.pubescens showed an obvious seasonal pattern of spring > summer > winter > spring,accounting for 45.51%,31.1%,13.8%,9.59% of the province’s total carbon accumulation,respectively.The determination of the maximum energy efficiency of P.heterocycla cv.pubescens would provide a scientific reference for the estimation of NPP and the quantitative evaluation of carbon sink in regional scale.
