【摘要】 利用1990—2010年宁夏森林资源清查资料,结合文献中的参数,初步估算宁夏灌木碳储量,并在此基础上,利用市场价值法估算灌木碳储量价值.结果表明,随着宁夏灌木面积的增加,宁夏灌木碳储量从1990年的76.25万t增加到2010年的272.69万t,年均增长9.8万t.1990,2000,2010年宁夏灌木吸收的CO2价值分别为0.53,1.21,1.89亿元,释放的O2价值分别为12.2,27.87,43.63亿元.如果在增加灌木资源面积的同时,加强集约经营,提高灌木单位面积生物量,灌木碳汇潜力会更加明显.更多还原

【Abstract】 Using Ningxia Forest Inventory Data from 1990 to 2010, and shrub biomass data in literature, carbon storage of Ningxia’s shrub was estimated. On this basis, the value of carbon storage was estimated by using the market value method.Results show that with the increase of shrub area in Ningxia, carbon storage of shrub increased from 76.25×104 t in 1990 to272.69×104 t in 2010, an average annual increase was 9.8×104 t. The shrub absorption value of CO2 was 0.53,1.21,1.89billion yuan, and the shrub release value of O2 were 12.2,27.87,43.63 billion yuan in 1990, 2000, 2010 respectively. If an increase in the resources area of shrubs, and strengthening intensive management, improving shrub biomass per unit area,shrubs carbon sequestration potential will be more apparent.更多还原
