1996-2013年火灾对中国森林碳汇损失估算的研究

摘要

Based on the data of forest damage accumulation and affected forest area in Chinese provinces ( city) during 1996-2013, direct and indirect loss of carbon sinks were estimated by the forestry industry standard ( LY/Y 1721-2008) Estimation of direct and indirect carbon loss caused by forest fire was 67. 52 × 106 t during 1996-2013, the economic value was$10. 129 × 108 . Among all loss, direct carbon loss was 45. 63 × 106 t, the direct eco-nomic loss was$6. 845 × 108 , the indirect carbon loss was 21. 89 × 106 t, the indirect economic loss was$3. 284 × 106, the average annual loss was 3. 75 × 106 t, of total carbon. An annual economic loss was $563 × 108.%根据1996-2013年全国各省份(自治区、直辖市)森林受害蓄积和受害森林面积数据,采用LY/Y 1721-2008《森林生态系统服务功能评估规范》 植被年固碳量计算方法,估算我国森林火灾造成的直接和间接碳汇损失量.结果表明:我国1996-2013年森林火灾造成的直接和间接碳汇损失量共计为67.52×106 t,经济价值损失达101.29亿美元,其中直接碳损失量45.63×106 t,直接经济价值损失68.45亿美元,间接碳汇损失量21.89×106 t,间接经济价值损失32.84亿美元,年均碳汇损失总量3.75×106 t,年均经济价值损失5.63亿美元.
