Abstract:

Objective: Carbon sequestration value (CSV) of (Phyllostachys edulis) forest were estimated and its spatiotemporal change was also examined,so as to exemplify an estimation method of CSV and contribute to a better understanding of the ecosystem service function of bamboo forest,thereby providing a theoretical and technical basis for carbon accounting and carbon trade. Method: Phyllostachys edulis forest in Fujian Province,accounting for 1/6 of the China's bamboo forest in area,was identified as a case study. We first fitted the biomass allometric equation and inverse models,then calculated the CSV of each bamboo component (including stand live culms,selectively cutting culms,bamboo shoot and soil) and also examined their changes from 2001 to 2014, using the data of stand increment,biomass,MODIS EVI and from questionnaires. Result: Over the past 14 years,the mean CSV of moso bamboo forest was estimated approximately RMB 553 million per time period (every two years),and a total CSV of the whole province was about RMB 38.71 billion. The CSV of bamboo stand and different stand components varied greatly; standing live culms,selective cutting culms,bamboo shoot and soil carbon accounted for 73.78%,16.11%,13.56%,and 3.65% of the total,respectively. During the study time,the CSV of moso bamboo forest showed an upward trend in fluctuation,with a increasing rate of RMB 157.69 per hectare per time period. Spatial distribution of the CSV showed a large variation; about 31.26% of the bamboo stands decreased in CSV,with an mean decrease of RMB 256.76 per hectare; about 68.74% of the bamboo stands increased,with a mean increase of RMB 640.80 per hectare. Conclusion: Moso bamboo forest in Fujian Province has shown an increasing carbon sink over the past 14 years. Compared with the three stand components,i.e.,standing live culms,bamboo shoot and soil,the selectively cutting culms has the largest contribution to CSV of moso bamboo forest ecosystem. Given that bamboo forests are at risk of degradation and very likely to be a carbon source without an intensive management,the selectively cutting culms is,therefore,an indispensable management measure to enhance the potential of carbon sequestration.
