【摘要】：在野外实地调查的基础上,利用地理信息系统(GIS)技术、地统计学方法及生态经济学价值量评估方法估算了广西斯道拉恩索公司两个原料林基地桉树人工林不同树种有机碳储量及其价值。研究结果表明:研究区3种树种单位面积土壤有机碳储量平均值由大到小排列为:桉树(36.38 t/hm~2)马尾松(35.02 t/hm~2)杉木(33.37 t/hm~2),结果与其他学者利用样地调查方法估算的结果相一致;研究区森林土壤有机碳总储量为7.03×10~5t,总固碳价值为842.61亿元;3种树种单位面积价值量由大到小排列为:桉树(436.52万元/hm~2)马尾松(420.28万元/hm~2)杉木(400.47万元/hm~2)。
[Abstract]:Based on field surveys, using geographic information system (GIS) technology, the evaluation method of statistical methods and ecological economics value estimates Guangxi Stora Enso two raw material forest base of Eucalyptus Plantations of different species of organic carbon storage and its value. The results show that: the study area of 3 tree species per unit area of soil organic carbon reserves the average value from big to small order: Eucalyptus (36.38 t/hm~2) of Pinus massoniana (35.02 t/hm~2) of Chinese fir (33.37 t/hm~2), consistent with the results of other scholars using the sample survey method to estimate the results of the study area; forest soil organic carbon total reserves of 7.03 * 10~5t, the total carbon sequestration value is 84 billion 261 million yuan; 3 trees a unit area value from large to small order: Eucalyptus (4 million 365 thousand and 200 yuan /hm~2) of Masson pine (4 million 202 thousand and 800 yuan /hm~2) Chinese fir (4 million 4 thousand and 700 yuan /hm~2).
